Windows 7 vs Windows XP performance in Black Ops. What the heck?

[pyide]

I saw some people saying the game ran better under Windows XP and since I still had an old install on a spare drive I booted it up, installed Steam to the same drive as my W7 Steam install, renamed of course.

First of all, this comparison was done on the same exact system with the same settings, both operating systems were thoroughly cleaned and installed with the latest and greatest drivers.

System Info:

Windows 7 64bit
Windows XP 32bit
Q8200 (Core 2 Quad 2.33Ghz)
4 GB RAM
GTX 260 (260.99 drivers)
Realtek HD Sound (R254 drivers)
DirectX up to date

Game Settings:

Black Ops MP
9v9 TDM botmatch on Grid
1680x1050
vsync off
com_maxfps 0
fov 80
4xAA
8xAF
Every other setting default, auto, or on.

Yes, that's a 34 FPS difference. Now in Windows 7 it will drop that low (or lower/higher) depending on the map and the amount of players. Even on an empty server it will reach the high ~40s on a map that's drawing more on screen and into the distance, like the view down the center here on Grid. The SP is another story and I haven't tested it yet, but I'm expecting similar results as it can get down to the 30s at times. I did experience some stuttering on XP initially until I cleaned out the drivers and reinstalled them, but that's gone.

This is the first PC game out of dozens where I felt the performance was poor enough that I booted into a different operating system to compare. When I first upgraded to 7 I did a few benchmarks and performance in most games was around the same, sometimes a tiny bit less, but nothing as drastic as this. Eventually as the drivers got better performance improved too, sometimes to the point where the same game would run better in 7, but generally it was comparable.

So what gives? Will I be forced to boot into XP every time I want a nice, fluid 60FPS BLOPS match? Has anyone else had similar results? Is there anything Treyarch or I can do about this?

Again, not saying this is the same for everyone or anyone out there. In fact I'd be surprised if there were many out there who are experiencing the same issues. A few replies say they had similar issues and it did help them, but that's not guaranteed. I am not suggesting this info will help anyone anyway, just sharing what problems I am currently having in the hopes they get fixed by the developers or the community can find a solution.

So to you Windows 7 guys who get angry after seeing the headline & post and end up skipping the rest of the thread: I am not saying XP is a better OS or anything like that, nor am I saying that it will fix yours or anyone elses problems in Black Ops. In fact I'm not a fan of XP at all and wish I didn't have to use it to play the game at a consistent clip. So there! I'm on your side. And yes, we all know you can expect a small loss in performance on Windows 7 with some games, maybe 1-5%, but not 40%. That's ridiculous. That's also ignoring the rare few that actually run better in W7 too.

Been thinking about this. Some games run better on Xp. Bleh, such a hassle to change. Maybe i try Go dual boot.

Wow.. Unexpected results.. I have windows 7 64bit and I got fixed >60fps(v sync)

Might make since if the Xbox code is based off of XP. Seems like they just through the Xbox code on a PC and expected it to run.

What kind of CPU do you have?
From the few benchmarks (http://nofrag.com/images/00564c/) I've seen it looks like Core i5s & i7s have the power to brute force through any performance issues those with lesser systems might experience.

It's possible if I overclocked my Q8200 I would get a solid 60 in Windows 7 with vsync too. I'm not going to attempt that with stock cooling though.

[Bob Zombie]

Maybe dx10 is forced when available, and they just never mentioned whether they updated the engine that far. I know a lot of games run worse in dx10 for some reason.

[dnottis]

Maybe but you cannot argue with his results. Clearly gay pwned.

interesting.... i use win7 64 bit and i'm not impressed by the performance of this game.

[pengu1NZ]

on win7 64bit and really not looking forward to going to XP but i would because I like it anyways and this gives me an excuse to

[pyide]

From my understanding it's still a DX9 game and engine. If it was DX10 there would be some parallels to the issues many people were having with performance in New Vegas, but I'm pretty sure it's DX9 all the way.

If anyone could tweet the original post to pcdev (http://twitter.com/pcdev), you would have my thanks. I don't want to create an account!

Have you tried running the game in compatibility mode for Windows XP while using Windows 7? Maybe you'll get the same result?

[pyide]

Yeah, I've already tried XP compatibility mode plus the options that disable visual themes and desktop composition. Absolutely no difference. Have tried changing the process priority and a bunch of other stuff already, too.

[TWal]

Wow... that is surprising. Let's keep this thread going guys... maybe we can get the attention of someone who can do something about this.
WE CAN ONLY HOPE!
I'm not setting up XP just to play this game. I'll just play arguably the best FPS game ever... CSS. ;-)

[Zwan]

Xbox360's have IBM PowerPC processors. The code for a RISC machine will be COMPLETELY different for x86 platform.

And no most of the code isn't anything like XP, for starters XP doesnt use a hypervisor. API calls are deliberately made similar and that's it.

Take your wrong statements somewhere else. Like Parliament... or church.

[masterthehero]

My theory is that Black Ops is utilizing DirectX 10 or 11, meanwhile if you run in XP the maximum DirectX you can use is 9.

I have noticed SIGNIFICANT performance differences between DirectX 10 and 9, namely that the later versions of the DirectX actually makes game run slower!

If any of you have Civilization V, you will see a MASSIVE performance decrease if you use the newer directX. However, if you use 9 everything rums very smoothly.

I think this FPS problem will be fixed if BlackOps is given the option to use DX9 instead of the later versions.

[Vaari]

Black Ops runs on an engine that uses DirectX9. It does not utilize 10 or 11 in any way. Windows Vista and 7 will use DX9 when the game is DX9. Please get that through your head...

[Majesty of War]

The amount of factually incorrect and disinformation in this thread is astonishing until you realize that most PC gamers now days have absolutely no clue what so ever.

I'm amazed often how the same users can use internet forums sometimes.

Steam Call of Duty: Black Ops forums is literally king of incorrect technological information.

I'll make a quick ball and say maybe windows 7 is using Dx10/Dx11 and XP is using Dx9? Or maybe because ones 64bit and the others 32? :confused:

Also, god knows how much rubbish is running in the background with your win7 boot and 4gigs of ram isn't a lot for win7.

Try running it under win7 under compatibility mode see what happens. and check out any commands to set it to use the Dx9 API

can this be done?
and if so...how?

[Vaari]

It can't be done. I don't care how many times I have to say this, Black Ops runs on DX9. Why the performance boost? One reason could be that XP uses less resources, meaning more can be used by the game.

[LuciferInTears]

hmmm...thats weird. I guess i'll install my old xp onto a new partition and dual boot; i'm kinda desperate at this point...

Quick question though: will i be able to run BO/Steam from within the windows 7 partition while still running xp? Or will i need to reinstall BO/Steam into the new xp partition?

[pyide]

One reason could be that XP uses less resources, meaning more can be used by the game.

Yet this is the only game in recent history that has severe performance problems for me in Windows 7 though. There's no logic to it. Resources alone wouldn't account for a 30+ fps difference when everything else I've played runs flawlessly on the same machine and Windows 7 OS.

I'm just looking for answers and help here, the only system / framerate comparisons I've had so far have been elsewhere from people with much better CPUs & video cards and thus much higher framerates. If someone with similar specs is experiencing similar performance that would be good to know.

We know it's DX9 but I still appreciate those posters are attempting to help, maybe those posts will stop now that people have resorted to name calling.

Not suggesting this will help anyone having issues by the way. This is only what I've experienced.

If you are desperate enough to try dual booting you can do it a few ways.
If you have enough space just make a copy of your steam directory and name it something else, then in XP download steam and install it to that directory. Your games should all show up. You'll probably want to delete your config files for Black Ops though, maybe verify the cache as well.

If you don't have a lot of space you can do the same thing but only copy the game files for Black Ops.

Or if you have the disc like I do, just install it from the disc and it will create a new steam install where you specify.

You can always just do a new steam install and re-download all the game files too, but that will probably take the longest depending on your connection.

I would not suggest installing Steam on XP into the same directory as it is on Windows 7. There could be a conflict, though I don't think steam even needs to be installed properly to work. You can make a copy of it into a new OS and just run the steam.exe and it should update itself and work.

[Rustybobo]

Ive been saying this for a long time but there is alway idiot with no knowledge of what they talking about to put down my words. Win XP will alway give you more FPS no matter the system you got.

[Kritik]

Haha, this is OLD news. Every "real" gamer knows games perform way better in XP. No game will perform better in Win7. NONE!

[SuperChikan]

I dual boot and get the same results. Absolutely perfect gameplay in XP and horrendous FPS/Lag/Stutter issues in Win7 x64

Those of you with duals try this - disable your sound in Win7 and you will probably see that your performance increases to that of XP's. If you disable sound in XP, you will see that there is no performance difference. I still believe its an audio issue, but driver related.

I believe there are issues with the game having to use Vista/7's audio stack API, which is significantly different and more restrictive than XP's kernel mixer.

[pyide]

You should check out some benchmarks sometime. I've seen more than a few games get better numbers on Windows 7, including Far Cry 2 and Call of Duty 4. CRAZY.

Generally it's closer than it's not, maybe 1-5 fps difference max, but nothing like this. Windows 7 is actually quite awesome. I get depressed when I have to use XP for anything these days.

Didn't help me, unfortunately. Disabled the device, uninstalled the audio drivers, and even disabled the on board sound entirely from the BIOS. No change :/

It's DX9, there's no dx10 redist or dx10 dynamic link libraries.

[pyide]

So what's the proper way to notify Treyarch or Activision of these issues?

I saw another thread here where someone mentioned they had big framerate drops in open areas too, but when I came back to reply to it with this thread it was deleted / invalid. ( http://forums.steampowered.com/forums/showthread.php?t=1610110 )

Someone on another forum told me he's having similar issues with a Core i7 / 260 / 6GB ram on Windows 7 which is even worse because that system is clearly superior to mine.

Damn.

[Monga]

With my old laptop, 1.5ghz core 2 duo, integrated graphics I used to play CS:S, and with such low FPS you notice even a small difference, with a custom config on XP i could average around 30-40FPS, Vista was unplayable, around 20FPS, and 7 was around 25FPS with HEAVY lag whenever smoke grenades were used.

XP runs games better, not sure why as I ran the same directX on all operating systems, I think gfx drivers are just better optimized for XP systems.

[pyide]

I'm sorry but you can't really compare what you experienced with a system with integrated graphics and an older game like that.

Again, I would believe Windows 7 was the direct cause if every other freaking game I have experienced similar issues, except they don't. In fact, some run better on 7. Most are comparable as I've already said. So why is Black Ops the odd one out and seeing a ridiculous 30+ FPS difference? It's baffling.

Initially in the W7 RC1 days, when the drivers weren't all that great and still new or built for vista specifically, some games would see a difference of a few FPS lower (a few being 1-5) on my system - but not anything even close to this.

[spieslikeus]

Can you run the game in windows xp compatibility mode? Maybe that will improve performance?

My bad. Thnx for taking the time to point it out. I'm on Windows 7 Ultimate 64bit. I would hate to dual boot into xp just to get 30 frame increase. There has to be some other tweak to run it using Windows 7. Makes no sence to release new software that runs better on older software. No Sence what so ever..

[ThE_MarD]

Heyyo,

Yeah XP has always been better at running games due to less cpu and memory useage.. that's a given. I prefer Windows 7 for boot times since I do 64bit and I found that XP took longer with the same amount of applications I have installed and set on boot.. besides with high hardware specs I don't really notice any framerate issues... I should put XP on my Gateway lappy though since it's not super strong. :P

[denis_fdrv]

ALL freaking games run better on Windows XP than on Win7, let alone Vista. Because XP consumes much less of your system's resources, simple as that. Some games run a bit better, others - considerably better like in this case. If a game is well optimized, you might not see the difference. But with a garbage like BO, performance- and optimizationwise, the difference becomes obvious. This is one of the reasons I'm still on XP - the best OS for gaming! If XP had DirectX 10/11 support, Win7 would not even be in my dual boot...

[Vaselkov]

Almost in all games XP have more FPS than Win7. I get 57 FPS while sitting on the HAVANA balcony and looking without ADS into police car. And on XP I get 78FPS in the same spot. ;) I have Intel Quad 3.2GHz 4GB Ram & HD 4870. By the way Dual Boot FTW. :D

I agree for the most part, but with Windows 7 you can configure it to the point to where it doesn't take much more resources than XP (turn of all the aero eye-candy, disable non-essential services etc.) I have multiple boots of Vista, WIn7-32 and Win7-64. I had recently deleted my XP boot, thinking I didnt need it any more, because most games I play play just as good on Windows 7, but BLOPS showed me that was a mistake. Reinstalled XP, installed BLOPS on it, and now all is good with gameplay.


Even if they fix Windows 7, I'm going to keep my XP boot just in case this issue repeats itself in future games.:rolleyes:

[Dark_hunt3r]

Yhe results although initially impressive are somewhat devalued.

Your Win 7 installation is your main OS, and XP installed to a spare drive. The problem is as you use your computer you install uninstall lots of software, your registry becomes slower and slower. More things are going on in the background,

To give an accurate result you need to run the tests again, but with both XP and Win 7 as Fresh installs, it is the only way to get an accurate comparison, the average FPS for the game will be different in each OS but I doubt the difference will be more than 5 FPS over all

Lots of people are claiming it is so much better on XP, yet if you read through these forums you will find many posts from people running XP who are having a lot of problems.

If you have the time, and the inclination do a fresh instal of each, latest drivers, latest updates and service packs, nothing else running and then run side by side comparisons, don't forget each test must be exactly the same on each OS, and because BO can be so random with its FPS drops you will need to run each test 3 times and average your data

Personally I wouldn't be bothered, I have an e8400 and although it took some tweeking I get a smooth 60 FPS on Win 7 and a lag/hitch free game

[Thrymm]

Not enough testing time directed by Activision, so it isnt totally Treyarch's fault. Customers now pay for a semi workable beta, and if it is the PC version at console prices.

In my case, WinXP is the main OS, installed more than year and a half ago and has tons of software. WIn7 has been installed several months ago, barely used, with minimum software installed. And the performance, as expected, is at least 30 FPS higher in XP also much less stuttering there. You may get used to your runs-OK-for-me performance on Win7, but it does not make it better compared to so called "outdated" system. BTW having 80-125 FPS here. Also, on my "outdated" XP I can take advantage of hardware sound acceleration for my Creative SoundBlaster card, which simply does not work properly on "superior" Win7.

Please don't be defensive, I am not trying to troll you or devalue your post, I was just trying to point out where some of the results may be coming from. I am just saying that the few who have noticed increased FPS from reinstalling XP may well have also received a significant boost by reinstalling a fresh Win 7 also (highly likely too) though XP should run 5 - 10 frames faster anyway.

My steady 60 FPS is not an indication of overall FPS, I have V-Sync on so it limits FPS to 60 anyway. If I remove V-Sync I get approx 120 FPS in some places, and normally ranges around 90 FPS but it doesn't play as smooth as when v-Sync is on

Interesting what you say about your creative sound card, I came across a fix that stops sound stutter for a lot of people , there is a command in the config file seta snd_khz "48" which sets the sound to 48 Khz (48000 Hz)altering this made no difference but matching your sound card to it fixed it, see here

http://forums.steampowered.com/forums/showthread.php?t=1606757

Would be interesting to see if your reinstated your Creative card and followed the instructions on that post to see if it would then work on Win 7

And again I am not trying to devalue your post, you're trying to help people which is great, I am just pointing out a counter argument because returning to an old OS is not always the best option just to play one single game, especially when some tweeking makes the game run ok (by that I mean perfectly fine and as smooth as CoD 4 (albeit without shadows)and a future patch will fix any issues

[denis_fdrv]

No problem, mate. We are all in the same boat here and all just want to make the game run as good as possible.
As for switching to Win7, I personally will not do it anyway even if the BO turns out to run there as good as or almost as good as on WinXP. There are several reasons for that in my personal case:
- No hardware acceleration in Win7 while I still use EAX in some older games. Also use EAX effects to emulate 5.1 on 2.1 system - works great in COD, but not audible in WIn7.
- The problem with monitor refresh rate - Win7 shows the correct/exact refresh rate of your monitor (in my case it's ~59.6 instead of 60 Hz), which causes problems with some games that require exact 60Hz. It can be overwritten by some utilities, but it's another unnecessarypain in the *ss.
- My UPS (Eaton Powerware 5110) has no drivers for Win7 and the software switches off the monitor on boot. Can be avoided if I don't use the software, but in this case the PC will not be able to turn off automatically in case of power failure. Not a big deal, but another unnecessary pain in the ♥♥♥.
- Simply with any game I tried to run on both WinXP and Win7 the performance is always better and smoother on XP, especially heavy resource-intensive 3D games.

The only con for Win7 IMO is DirectX 10/11 support, but it's just not implemented good enough in games so that I want to change the OS.
I'm not trying to incline anyone to switch to any of the both operating systems and not trying to be defensive. Just telling about my experience and about the primary reasons that still keep me on XP. As for the eye-candy of WIn7 - yes, it looks cool - but it's not really important for me.

OP, go to your multiplayer config and turn r_allow_intz from "1" to "0."

r_allow_intz enables your FPS to increase on specific maps, while on others, it will decrease.

I mean, it may not do anything for you, considering you took two pictures on two different OS under the same circumstances, but it's worth a shot considering the last paragraph you wrote.

Thanks for the tip but unfortunately it had no effect.

[Falkentyne]

I get 10+ higher FPS in windows 7, without any of the annoying menu pauses/freezes that I get in XP, and without that freeze after a map loads. The game is completely flawless on my W7 partition, and EVERYTHING is much faster. Alt tab takes mere seconds, instead of 30+seconds in XP. Map loads are snappy as pie. Note that I also dual boot.

Now, if I disable 2 cores in W7, then the game becomes basically unplayable. FPS doesn't really drop much at all, but it starts stuttering horribly. Zero problems with 4 cores....

Quick question. My computer currently has two hard drives, one that has my main OS Windows 7 64 while the other hard drive has Ubuntu installed on it. The computer boots and asks which OS to boot (if no option is selected it goes to windows 7 as I set it to my primary hard drive).

If I was to take off Ubuntu and install XP on that hard drive, would I just be able to stick the CD in there and select that hard drive to install XP on it, and then it would load the computer the same way? (asking me which one I want to boot?) Or would I have to install XP differently?

...and people are wondering why some prefer consoles... it's games like this that makes me wounder why I even bother with buying a gfx-card for games anymore...

The dual-boot is set up automatically during the installation of an OS only if the OS you're installing is later than the OS you want to keep. Thus, if you install XP, it'll load it as if there's only one OS installed. Though, it is possible to create the dual-boot manually by editing the required file or using special programs. But beware that manual dual-boot setup is a rather complex task and if you make a mistake you will not be able to load the OS at all. If you need details on how to set up the dual boot when you installed XP after Win7, google it. Good luck.

did you guys ever think about the fact that windows xp is capped at DX 9? and windows 7 can go all the way to 11.

that alone will take away a lot of your FPS.

This is relevant only for games that support directx10/11 and BLOPS is not one of them.

[analyst88]

Yet this is the only game in recent history that has severe performance problems for me in Windows 7 though. There's no logic to it. Resources alone wouldn't account for a 30+ fps difference when everything else I've played runs flawlessly on the same machine and Windows 7 OS.

I'm just looking for answers and help here, the only system / framerate comparisons I've had so far have been elsewhere from people with much better CPUs & video cards and thus much higher framerates. If someone with similar specs is experiencing similar performance that would be good to know.

We know it's DX9 but I still appreciate those posters are attempting to help, maybe those posts will stop now that people have resorted to name calling.
I don't want to bust your balls, but I don't have any problems running Black Ops maxed in Windows 7 64bit.

[mujahieed]

I only switched to Win7 last yaer from XP. So yeah XP is better for gaming generally but not am much anymore.

[Hi5_impala]

Screen shot on Win 7 has more going on in that frame... 4 or 5 other players in front of you, your own characters arm moving on screen reloading etc etc. I duno, My game runs great on Win7, dont have fraps dont know the command for the FPS in game but im willing to bet its over 75 FPS for me at all times.

[turtsmcgurts]

I can confirm this, after seeing the original post I gave XP a 50gb partition on my HD (dual booting) and I am absolutely 100% stutterfree with constant 100 FPS.


With Win7, Ultimate 64bit, it was unplayable with the stutter and 40-50 FPS.

[tet5uo]

Too bad I have such new hardware there aren't even XP drivers available for some of it.

I have a ridiculously powerful system, so I just brute-force my way to decent FPS, but even I notice some drops in FPS into the 50's when looking into the open area in Havana for example.

I couldn't use my 3 screen surround and three way SLI with winXP either.. it can only use 2 GPU's.

[__PraetoriaN__]

Okay guys, to be honest I did not read all the comments, so this might have been mentioned, but again:

It's been said on like day 4-5, here, on the STEAM forum by someone, that after he called the support they said it's a DX10-11 issue, CoDBO is DX9 based, which itself wouldn't be a problem, but it uses DX9 commands which DX10-11 somehow can't handle correctly, so that's why the game is smooth as butter on XP.

For me I simply could not play the game from W7 (well I could, but It was like a PowerPoint presentation), while on XP it's almost perfect, and I have a mediocre computer. (Core 2 Duo E7400 @ 2.8GHz, 2GB DDR2 RAM @ 1066MHz, and an ASUS 8800GT)

But even I reposted this 3-4 times already, and I saw other people do it also... Aren't you guys READING the forums, you're just posting your own things mindlessly, or what?

1) I was just reposting what that guy said almost 2 weeks ago.
2) If you're so smart, could you please explain me (and all of us who are wondering about this difference), why does the game runs miles better for EVERYONE, NO MATTER OF WHAT HARDWARE THEY HAVE on "pure" DX9 than on other DX versions which "includes" DX9?
3) And if you're at it, since you're so smart that you know it, why don't you send an email to Treyarch which includes the W7 fix, or atleast a "how to" description of it? Hm?

If you can't give a valid answer to question number 2, please just stfu, and don't troll people who are trying to help, kthxbai.

does anyone know how to setup dual boot with win7 64 bit and xp 32 bit?

[turtsmcgurts]

does anyone know how to setup dual boot with win7 64 bit and xp 32 bit?

How to dual boot XP and 7. (http://lmgtfy.com/?q=How+to+dual+boot+xp+and+7)

I found it's far easier to do it if you install XP first. Just make a 100gb partition for it (depending on your HD size) and put your \steam\ folder in it.

Then install Win7 in all the unused space. There's something like symlink or syslink (something like that) and you can link your 7 hard drive to XP, so you can play your steam games from XP on your Win7.

[__PraetoriaN__]

does anyone know how to setup dual boot with win7 64 bit and xp 32 bit?

Well if you did not partition your HDD into 2 (or more), the only solution is format C: , or if you have a spare HDD you can use that one as an XP runner.

That's why I always partition it... There are a few things for which I need XP unfortunately by default, the current BO status just added one more... :S

[stevenxowens792]

The weird thing is the way that Windows 7 handles dx9. To compare other games, (ie Bfbc2), dx9 you get much higher frame rates in win7 with dx9 (unless you have a weak cpu with strong gpu).

Each game is different. I appreciate everyone who tested both xp and win7. Very interesting results.

TO THOSE WHO GOT MUCH BETTER RESULTS IN XP VS WIN7, DO YOU HAVE DUAL CORE PROCESSORS? Anyone try this with an I series cpu? Do the I series respond the same way as the dual cores?

Thanks again to everyone. StevenX

[turtsmcgurts]

TO THOSE WHO GOT MUCH BETTER RESULTS IN XP VS WIN7, DO YOU HAVE DUAL CORE PROCESSORS?

Yes, I do. I also noticed most/if not all people in the original thread who said installing XP helped also had dual cores.

[lodidodi]

hmmm...thats weird. I guess i'll install my old xp onto a new partition and dual boot; i'm kinda desperate at this point...

Quick question though: will i be able to run BO/Steam from within the windows 7 partition while still running xp? Or will i need to reinstall BO/Steam into the new xp partition?

Yes it will work. Just go into correct partition/harddrive,find steam. Doubleclick.
I rarely reinstall steam. Got it on a seperate hd at all times

[lostatsea]

The game runs beautifully on windows 7 64-bit on my PC. Maybe its the 8gb ram:P

[Timmeh317]

If it is a Direct X issue, wouldn't forcing DX9 fix it? Is that even possible in Windows 7?

[pyide]

Understand, (for me) the map could be empty of all players on Windows 7 and the framerate would still suffer greatly. It would be faster overall on both operating systems obviously - because there are no players at all, but it is not that much lower than XP because there are a couple more players on the screen and the arm is being drawn. I purposely did a 9v9 botmatch so the strain on the CPU would be the same from the amount of AI players, even though they seem as dumb as bricks and probably have minimal impact. And because it's easier to get to the same spot for comparison shots without dying than with humans.

I'll do a timedemo when I have time in the future if the game supports that and post the results if you need to see a precise frame by frame comparison to believe this.

It's hard to get 9v9 players in MP or even dumb bots like this to line up exactly how you want but I did the best I could.

[tet5uo]

If only they'd included some kind of benchmark or timedemo.

Since those have no use to console users, they're definitely not in the game :)

I get perfect frames in Black Ops under win xp but the stuttering is NOT fixed, single player stutters almost every 5-10 seconds, and sometimes severe stutters are experienced which cackle the sound and stop guns from shooting. This is a serious issue that needs to be fixed asap, I can sprint across every map in Crysis 4x as fast as normal throwing grenades and firing rockets and not stutter even ONCE.

This game is extremely unimpressive graphically, there is no reason for stuttering other than a bug.

It looks like there is a timedemo command if you pull down the console and type it in. I tried running a quick demo I recorded for this purpose last night and it works, but there's no way to see the results / data as far as I can tell. ARghghdf.

The console doesn't display the numbers like normal games would and I don't see a text file with the info or anything.

I was getting terrible stuttering in XP as well before I removed and installed the most recent drivers for my onboard sound. Maybe that will help you, maybe not. Both W7 and XP are as smooth as can be for me, it's just the overall framerate is way lower in one.

[VistaSStoned69]

sorry but i need more then 1 pic

Yeah. Maybe someone else can help out but I'm not normally a dual boot guy. I tried messing around with dual boot loaders back in the Win7 beta days with poor results.

Basically what I have is 4 separate hard drives. 2 of those have their own operating system and I "dual boot" by switching the boot priority for the drive I want to boot with in the BIOS. About the only thing I had to do initially is switch around some drive letters in disk management so my 3 data partitions on the other 2 of 4 hard drives were in the same order on both operating systems.

Going into the BIOS and switching the boot order of the drives around takes slightly longer than simply choosing which OS you want to boot into with a loader, but it's much simpler for me.

As for Steam, I did a separate install on each so there would be no conflicts, not that I know there would be any, was just being safe I suppose. I know the program doesn't even need to be "installed" as it were and you can just copy the main files and the games you want over and it should update itself and work when you launch the steam.exe (https://support.steampowered.com/kb_article.php?ref=7418-YUBN-8129). I personally have Black Ops on disc from amazon so I just installed it and a new steam to a different directory on the other OS.

I love Windows 7 and wish I wasn't having this issue. I really, really hate going back to XP as I think I already mentioned in this thread somewhere.

I'm not saying this is the way it is for everyone, just that it is this way for me.

Like I said a few replies above too, I will do a timedemo and post the results for those that want an exact comparison of the two. If someone can figure out how to see the data when it's done, I'd really appreciate it.

If you really aren't satisfied and actually want me to I'll take a lot more screenshots, on every map if necessary, but I don't have time for this right now. I'm on my way out the door to have thanksgiving.

[joshmans_90]

What kind of CPU do you have?
From the few benchmarks (http://nofrag.com/images/00564c/) I've seen it looks like Core i5s & i7s have the power to brute force through any performance issues those with lesser systems might experience.

It's possible if I overclocked my Q8200 I would get a solid 60 in Windows 7 with vsync too. I'm not going to attempt that with stock cooling though.

Lol. BRUTE FORCE CPU, FORM I7TRON.

[Shadow11792]

Maybe dx10 is forced when available, and they just never mentioned whether they updated the engine that far. I know a lot of games run worse in dx10 for some reason.

They didn't upgrade the engine thought its the same one as in MW2

Obviously something is wrong in your Win7 setup, since u have such bad performance. I think the problem is the graphic driver.
Uninstall the driver, reboot in safe mode, use driver sweeper to make sure u get rid of all the junk from the old driver, reboot again and install the same driver, then reboot again. Then tell me if that helped any..

Why is everyone missing the most obvious.

Yes you are standing at the same place but look right a head and also at your minimap.

There are more players in view on your win7 shot and there are more players being clipped out on your win7 shot behind walls (Look at minimap there is atleast 8 players right infront of you as seen on minimap, incl whoemver might have ghost. On winXP shot you have 2 inc whomever have ghost).

[kuddo]

This game is the same DX9 engine, because it has the same engine as MW2 which has the same engine as MW1 (with a few modifications here and there) WHICH MW1 has and old stuffed Quake3 engine (modded and ultra-modded).

So it seems like a game that should run on medium details on a P4 @3ghz and a 8500gt video card with 1gb ram now needs a tank PC.

I took these both on empty servers after doing some benchmarks with a recorded demo using FRAPS since I can't find a way to see the timedemo data in the game itself. Yes, the framerate is much higher on both because of the missing 17 bots bringing both down to real gameplay type conditions, but the difference is even larger between the two if you had not noticed.

Windows XP

Frames: 4956
Time (ms): 60000
Min FPS: 59
Max FPS: 104
Avg FPS: 82.600


demo file used for both (http://www.filedropper.com/fpstest3)

It's on Cracked with 9v9 bots. If you didn't already know, to record a demo you type \record and the name of the demo. \stopdemo stops the demo recording. \demo demoname plays back the demo. \timedemo demoname runs a timedemo.

So I had recorded a demo in game for a little more than a minute. Using FRAPS' benchmarking settings I chose to save the min/max/avg stats and stop it automatically after 60 seconds. I started the benchmarks on both right after match start countdown, which you will see if you play back this demo.

If you have a very similar system and want to benchmark this demo to compare, download and place the fpstest3.dm_7 file into your call of duty black ops\demos folder. You may need to create the demos folder if it's not already there. Then in game you can playback the demo by typing \demo fpstest3 and hitting enter. If you want to benchmark it get FRAPS and set it up the same way I did. Then start the benchmark with your benchmarking hotkey after the match start countdown hits 1. It will stop automatically and save the results in a .csv file in your FRAPS\benchmarks folder. You can view the data in notepad.

edit: As ScaryStuff mentioned, you can see the timedemo results in game if you use shift+~ to open the console and scroll up a bit with the page up key. It's not as detailed as FRAPS as it won't give you the min/max fps, just the average and the number of seconds it takes to run.

Now i can play smooth, no stuttering at all, i didn't touch the settings at all (video settings all default), i've got Vsync on stuck at 60 fps, in W7 32bit i never got past 30 fps in open areas and cpu always at 100% both cores. In xp both cores hardly go past 75% and they can touch a minimum of 35% cpu use in a full server.

I tried everything to make cod work in w7, and i always had audio loops, stuttering and really bad bad performances. This is the only thing that really fixed completely my game, you should all really consider trying. It's worth it.

This makes me sad =/

[ScaryStuff]

Anyway, as u all probably already know, Windows 7 handle sound a lot differently from windows XP. Those of u that get better performance when testing under XP, could u please repeat your test but this time disable all sound sources under both Win7 and WinXP, so we can pinpoint if it is the sound that is causing it. I think it is, but I don't have any XP installed to test with..

How do you scroll the console up in Black Ops? I tried the standard page up / down and arrow keys, mousewheel too. All I see is the same one line of the console (http://img541.imageshack.us/img541/5760/consoleq.jpg) and the settings I previously typed.

Same constant stuttering issue here, and I'm on Windows 7 x64 Ulti

[pyide]

Anyway, as u all probably already know, Windows 7 handle sound a lot differently from windows XP. Those of u that get better performance when testing under XP, could u please repeat your test but this time disable all sound sources under both Win7 and WinXP, so we can pinpoint if it is the sound that is causing it. I think it is, but I don't have any XP installed to test with..

That's just me though. It may very well help someone else!

How do you scroll the console up in Black Ops? I tried the standard page up / down and arrow keys, mousewheel too. All I see is the same one line of the console (http://img541.imageshack.us/img541/5760/consoleq.jpg) and the settings I previously typed. It would have saved me a lot of hassle if I didn't have to use FRAPS.

Remember to hold down SHIFT when u press the console open key, so u get a full screen console. Then use page up/down. u have to scroll up quite a bit to see it..

Are u saying u get identical performance in win7 with and without sound sources? Realtek?

[BlazingNova]

Windows 7 64 bit here.

I always have more than 60fps (Phenom II 955 Quad core ftw)

[pyide]

Not identical, but there was no perceptible improvement. It was still running ~30fps lower. Yes, Realtek. I'll benchmark that too if you want but it's not going to help anything. Right now I'd like to do the in game timedemos since you told me how to access the full console (Thanks btw!). I've gotten so used to just pressing ~ in source engine games.

Game runs great for me on Win 7

Xp is old. I want it to die already.

Point is, its great that it runs BO better for you on XP, but theres so many hardware/driver combinations and this is probably where this difference in performance is coming from. Win 7 has so much more to offer. But if your happy with an outdated and terrible looking OS then who am i to tear you away from it...

Oh and Win7 is more resource intensive. Q8200 aint so hot

[imhigh]

of course that win xp will perform any game better, there is no need for win7 just because of better looking interface and some small changes, my xp runs like a beast i have only 11 processes running while playing the game and its FLAWLESSSSSSSS

everybody install the old good xp, disable unnecessary services and there you goooo, nothing bad about xp

[BzzRain]

To Be Honest i don't get it..

Since when are we going to be forced to boot on a 9 year old Operating System to play a 2010 game fluently?

Am i the only one missing the point here ?

[imhigh]

OMFG so what if its 9 YEAR OLD OS? tell me what do you have on your ♥♥♥♥ing win7 that i dont have on my xp?

nobody is forced to use the 9 YEAR OLD OS, everybody can use what they want, but then dont cry about poor performance on your win7 systems

[tehxman116]

Nothing bad? If you had a good enough system, theres no way xp can exploit its full potential

Over 4gig ram? oh wait it cant do that. 64bit? oh wait, cant do that either (dont even bother mentioning that xp 64 abomination)
Direct X11 anyone?

lol what win 7 has that xp doesnt eh...

[imhigh]

xp 64bit can without problems run more than 4gb ram dont talk what you dont and didnt tried
and wtf about dx11? tell me 2 worth playing games using dx11 TROLOLOLO

[lec666]

Of course it will run 10x better on xp,look at the system requirements to run that OS....
The difference in CPU speed is,for sake of argument just to run Win7 is 700MHZ more than XP
This is why C2D users who overclocked their chips to 3.4-3.8GHZ+ can run the game perfectly .

Here's What You Need to Use Windows XP Professional
•
PC with 300 megahertz or higher processor clock speed recommended; 233 MHz minimum required (single or dual processor system);* Intel Pentium/Celeron family, or AMD K6/Athlon/Duron family, or compatible processor recommended
•
128 megabytes (MB) of RAM or higher recommended (64 MB minimum supported; may limit performance and some features)
•
1.5 gigabytes (GB) of available hard disk space*
•
Super VGA (800 x 600) or higher-resolution video adapter and monitor
•
CD-ROM or DVD drive

Some of you guys are so ret@rded and will never get it.
Those of you who can't run it well on Windows 7 is because you
hardly even meet CPU requirements & run so much bloat in the
back ground. Installing on XP is like shutting your sound off

You really are missing the point here..

Windows XP is an OS that isn't in stores anymore.. How do you expect someone who buys a new PC, and has less understanding on "downloading" , to get Windows XP on his PC.. Since every new one is PREINSTALLED with 7.

Open Your eyes and don't look beyond your own nose mate..
This is not to flame you, but you just can't always choose between things if you don't have the knowledge.

[God!]

I refuse to do this stupid ♥♥♥♥ sucking 3arch should fix this ♥♥♥♥ not me i want my money back xp sucks they need to quit releasing those service packs for it and just let it diediedie!!!!!!

dude, those who just buy new pcs with preinstalled win, they dont care about any ♥♥♥♥ they just surf and rarely play games, if there are people who doesnt know to make a query in google "windows xp sp3 download torrent" they dont deserve to have a pc

and what does that have even to do with this theme, ive just wrote here that xp is running better

[tehxman116]

Pretty sure MOST (i stress that for a reason) people that have problems are probs people that...dont have a clue? run so much crap on their pcs, have outdated hardware etc.

Oh i love the ones that have an overclocked system and all they ever complain about is everything crashing, blue screens etc. Always overlooking their overclock and just blame developers, software or hardware strait out.

[Ataraxis]

Why are people saying to 'force' it to run on DX9?
All COD's since COD2 are using DX9, they don't utulize DX10 nor Dx11.
It's a shame realy, realising a game on a quite outdated engine which runs ONLY DX9 and still manage to get all these problems on all these up-to-date systems.

[The_Gump]

Haha, this is OLD news. Every "real" gamer knows games perform way better in XP. No game will perform better in Win7. NONE!

With my old laptop, 1.5ghz core 2 duo, integrated graphics I used to play CS:S, and with such low FPS you notice even a small difference, with a custom config on XP i could average around 30-40FPS, Vista was unplayable, around 20FPS, and 7 was around 25FPS with HEAVY lag whenever smoke grenades were used.

XP runs games better, not sure why as I ran the same directX on all operating systems, I think gfx drivers are just better optimized for XP systems.

ALL freaking games run better on Windows XP than on Win7, let alone Vista. Because XP consumes much less of your system's resources, simple as that. Some games run a bit better, others - considerably better like in this case. If a game is well optimized, you might not see the difference. But with a garbage like BO, performance- and optimizationwise, the difference becomes obvious. This is one of the reasons I'm still on XP - the best OS for gaming! If XP had DirectX 10/11 support, Win7 would not even be in my dual boot...

See Below (u saved me having to write the same thing bboy500)

did you guys ever think about the fact that windows xp is capped at DX 9? and windows 7 can go all the way to 11.

that alone will take away a lot of your FPS.

The part about only DX9 and outdated engine. Its annoying but hey Activision dont care anymore as we all know. Money money money. The game doesnt look terrible, it gets by. So they think its kl to use same old ♥♥♥♥ to increase their profit margins due to less development etc...

Yay again, and heres why OC'ing to over 3.0Ghz helps... Console's have mega powerful, multi-core CPU's that do 80-90% of the processing and this game, like BC2 when it first game out, suffers from horrible PC optimization.. lazy, cheap work by the Dev's in the rush to make money...

EDIT : Prolly being unfair to the Devs here... blame Bobby actually...

[p0rks0da]

I run Windows 7 64bit, the only thing that helped me was to change the default sound format to (16 Bits, 48000Hz) in the Realtek HD Audio Manger.

Its not a big deal changing it back when I'm not playing and it has drastically improved stuttering in multilayer.

[Herodotus07]

If it is a Direct X issue, wouldn't forcing DX9 fix it? Is that even possible in Windows 7?
Nope. It won't run on many, many XP systems with all drivers and software up to date. The freezes/crashes are still gamebreaking -dreadful.

I can't play at all on Windows XP 32-bit SP3.

Some of you need to read more of the thread I think because I've had to repeat myself far too often and I'm going to do it yet again. No, I do not like XP. This is not an anti-Windows 7 post. And I'm definitely not suggesting XP will make everyones or anyones problems go away.

The only reason I even dug out that old drive was because this is the only game that I have severe performance issues with in Windows 7. THE ONLY ONE. Do you guys all comprehend that? It's just so freaking bad, especially in single player. So bad it made me desperate enough to boot into XP again and try it after seeing a few people mention they had better results with that OS. Before I even thought about doing that I tried every 'fix' and 'tweak' posted here and elsewhere along with the usual stuff I know to try from dealing with PC games for more than a decade, with no real results. I honestly wasn't expecting any difference in XP and there would be never be a reason for me to do this with any other game in Windows 7 because they run just great, and some are much more resource intensive than Black Ops. It was a last ditch effort and it's baffling to me why it's the only game I own with this problem.

Obviously it's something wrong with my setup and the game itself, but there is nothing I can do to fix it which is why I am posting this stuff here, hopefully for the purpose of seeing if it's a widespread issue and something real that can be fixed by the developers or tweaked by us on our own. Other people have posted about having similar problems so I know I'm not alone in this. Understand this is pure performance loss. Neither OS is stuttering or hitching like many others are having problem with. Both run the game as smooth as can be, but one is roughly 30FPS faster.

If you guys don't have anything helpful to contribute, please stop bumping the thread. Or go ahead and keep on replying with the same BS that's already been said multiple times. We all know you can expect a small loss in performance on Windows 7 with some games, maybe 1-5%, but not 40%. That's ridiculous. That's also ignoring the rare few that actually run better in W7 too.

[d3stroyah]

for what i saw the issue is mostly dual core related and i also think it's something with the audio department (something really really wrong).

Also something i noticed: when you start a game in XP at the beginning the framerate is kinda ♥♥♥♥ty (30-40) for 3 seconds, then it raises up until 70-90. It's like Seven misses that part, starts at 30-40 but can't somehow manage to take it up to the right level (failing loading something and looping the operation continuously?).

That's what i know. XP rocks, for now (AT LEAST 30 fps gain vs w7 and ofc no freezes or lag)

Yeah, I noticed that too when running the benchmarks on XP, mine would even start out at like 8 then raise up to 30 in a second then 90. Perhaps it's worse at caching / loading the initial data?

Seems like 7 loads everything just fine though. I have no idea :(

[w0ooot]

thnx very much OP
atlast am able to play this game.
my fps:
125-avg
170-in rooms
70-in fights

before on win7 my fps was between 30-60
my spec:
E8400
4GB DDR3
HD 5850

[Garone]

Similiar performance to your W7 results on a similiar system, though I run Vista.

[mikemartin1200]

alot of stuff

its amazing how much better it is on xp. im even starting to question why i even went to win7 in the first place. in no way shape or form was this game meant to be played on win7.

[Rafadagaffer]

Bump.

I just installed xp and updated to the latest drivers etc and I can confirm that the game runs buttery smooth compared to it running on windows 7, now granted my rig is not the greatest but it is still above the minimum specs posted by Treyarch

E8500 @ stock
8800gts 512mb ,need an upgrade I know :(
Creative X-fi Xtreme Gamer
4GB Ram

before on 7 I was getting at the most 80 - 90 fps with drops to around 30 or 20 when I turned a corner, ran into somebody or a number of other things. I'm getting a constant 60 + now at all times.

[dnottis]

I've forwarded this information to nvidia. We need JD_2020 and PCDEV to get this information now. Obviously, its gotta be something with DirectX and Windows 7 OR its something with the way Windows 7 handles audio.

[Dabigbom]

So yeah, I did the unthinkable (as some mongrels here might think) and I dual-booted the game on XP.

The results? Works it's way like a Thai masseuse. Silky smooth, no stutters, no weird drops in FPS on the long hauls, no weird audio hitching. It just works.

And to think I was getting paranoid about my ancient PC specs.....guess I've been proven wrong.

Long story short, the biggest fix for this game is to install it on a dual-booted WindowsXP and let the magic flow. However, running it at high - ultra, I now see the abomination Treyarch calls an engine, especially the horrendous texturing. Design-wise, it certainly does the CoD franchise some justice. Not much, but suffices.

Many thanks go out to the OP and mikemartin for this final and best solution. + rep

[Tearitup]

This worked for me also. I made a new partition, installed XP Pro, and then moved over Black Ops.

Game runs buttery smooth except for random DX crashes, which may be worse than the stuttering.

Verdict? The game ♥♥♥♥ing sucks.

Thanks for the suggestion though! I got a few good rounds in which what seemed like an entirely different game.

[Darek]

XP is gay

You are pathetic

[Buer]

Yeah thanks OP. I just setup a dual boot so I can run XP on my machine without having to format Win 7. And sure enough after installation of Black Ops it runs like it should. No issues what so ever.

Not sure why everyone is shooting down XP. It just shows that there must be some kind of issue with Win 7 and most likely the drivers it needs for any of the hardware you have.

CPU E8400
OS Win 7 64 bit/ Win XP 32 bit dual boot
Ram 6 gigs in Win 7/ 3 gigs in Win XP
GPU 9800 GTX+
Sound Realtek Hd Audio onboard sound device.

No more hitching/stuttering/issues when this game is run on my XP boot.

Edit: When I said being an issue with win 7 and it's drivers. I meant, Black ops not being optomized for that OS and such. I'm not saying it's Win 7's fault..heh.. It's obviously an issue with the game itself.

[backie]

its not just windows 7 i have the same with vista but i really doubt its the os at fault and not the game :)

[Buer]

its not just windows 7 i have the same with vista but i really doubt its the os at fault and not the game :)

Well I was refering to the game being optomized for said OS and it's hardware drivers.....

[Spada]

Who the F still runs XP brah. Srsly it doesn't matter, this POS game should run flawless on Win 7 no questions asked.

[backie]

why would u use the word optomized i really doubt they tried to make it work better on xp that would be completely rediculous its more likely sloppy work on there part

[anthonyguecho]

So I was one of those people who decided to run a dual boot and install the game on Xp, with 100% improvement take note it was dx 9. Decided to experiment and upgrade the dx to 10 and guess what? A very big decrease in performance. Direct X issue? Treyarch come on......this is ridiculous. I know that thier coders are aware of this XP thing and...hello lets fix it.

[minime2k]

This is not good. Treyarch.

Your technical incompetence shocks me beyond my description.

Treyarch, get some decent software engineers there...seriously.

Technical faults of Black OPS give you a bad name.

Particularly, This OS stuff is not acceptable. It's 2010.

[Ragonix]

I started off playing the game on XP 32bit and the game ran fairly decent on my 3.2ghz C2D, 4GB Ram, gtx260. The game stuttered every now and then, but it was pretty playable. When I upgraded to Win7 64 though, I stuttered almost constantly. I tried many config tweaks, but nothing helped. I bought a used q6600 and bumped it up to 3.4ghz, and tada, no more stuttering.

[rethxoth]

Has anyone tried (not sure if it's possible though) to force Windows 7 into using DirectX 9?

[FidelCastrol]

I'm not surprised at all. Quite a few games run way better under XP than Win7...but I've never seen that much of a difference in FPS, usually it's 3-5 more fps (using dx9, not talking about dx9-dx10 difference).

So I guess that's one more proof of Treyarch bad programming. How could they screw up a 10 years old engine like that ?! It's definitely beyond me.

[MIK3K]

Been talking about this Win 7 versus XP since Bad Company 2 came out and also Rise of Flight for flight sim fans. I don't know about the OP of this thread because I think he has a quad core, but definitely dual cores are having a harder time with Windows 7. Bad Company 2, Rise of Flight, Need for Speed Shift, Dirt 2 - unplayable for me on Windows 7 64 bit - BUT Win XP 32-bit on an AMD X2 4800+ and Nvidia 9600gt and these games run fantastic.

Read this from the developer of Rise of Flight (last paragraph on page) about how Windows 7 is not playing nice with dual cores on Rise of Flight - http://www.simhq.com/_air13/air_455a.html

Also, Black Ops ran choppy even on XP for me until the patches started rolling out. Now it runs as well as MW2 on XP (like they flipped a switch on my GPU and it started heating up finally and running smooth).

I really only use Windows 7 for Just Cause 2 (no XP support) - and work of course. XP for everything else.

[Euke]

Got XP and Win 7 in dual boot...unfortunately before loading a map in xp the game crashes to desktop. Same problem in single player. Any solutions to this or is this just another random bops problem?

[GamerofRage]

So, does it stutter on XP?

[spidypiet]

So, does it stutter on XP?
NO stutters
also me and a few friends reverted back to XP
and we experience major improvements
actualy the game is now FUN to play

- XP32 no stutters, no lagging 70 FPS

Go figure

[dnottis]

@Frostbite - what type of cpu (system specs) do you have? Thanks, StevenX

If it took him 3 hours to install XP, he's gotta have a low end machine... in that case nothing is going to fix poor hardware. Everyone else is reporting great gaming experience in XP with COD BO, so he needs to update his machine.

[dnottis]

The problem with this is that the xbox360 is so effing old that Windows XP would be the applicable generation during which these ports would've come over; so it makes sense that the game plays better on XP.

I'm wondering if the machines Treyarch was using for the PC port testing weren't running XP too.

We've gotta see these console die already. They are holding back gaming as a whole way too much.

[tet5uo]

I get LESS performance on XP then i do Windows 7. Not sure if it was related to my dual boot, but ive always had better gaming thru W7 then XP.

make sure to reinstall DX, you can find it at "steamapps\common\call of duty black ops\Redist\DirectX\DXSETUP.exe"

[reactioN]

also whats up with the "xp is too old and crap" stuff

if you dont need dx11, then xp is still the best os for gaming

[raptor]

WoW guys this thread is LEGIT

Im running gtx 470 q8200 3ghz and ive just installed winxp dual boot, tested them on both OS and yes Xp has never dropps below 60fps WITH shadows on, on win7 if i have shadows on it drops to 30fps. Also run 16 AA

GOOOD WORK !!!!!!!!!!!

[analyst88]

The fact that it has more security holes than a swiss cheese, looks horrible, needs reinstalling every 6 months to keep it from clogging itself up and SEVERELY lacks in funcionality doesn't mean anything to you?

The sooner microsoft drops support for that outdated OS the better.

[noodlesoup]

Just to point out, black ops is running on a game engine that was designed for DX9, which in turn, was designed for windows xp, aswell as the xbox runs DX9.

Basically, your getting crap performance because your hardware is afew years ahead of the game :<

By that logic I shouldn't be able to play COD1 anymore yet I get 1000's of FPS in that :)

[analyst88]

Windows XP slows down over time. That's a fact. Every WinXP PC I've had since XP's release (back in 2001) slowed down to a crawl after a while. Windows 7 doesn't. I can switch all the hardware I want (incl. motherboard), I don't need to reinstall it. Before XP I ran Windows Vista, before that win98, before that win95 and way before that windows 3.11. Believe me when I say that windows 7 is hands down the best iteration in the series.

I can't believe that people would still consider using a horribly outdated OS, let alone reinstall it, just to play a game.

I can't do without Win7's search function anymore, nor can I do without aero peek and other nice stuff windows XP doesn't have.

Different engine, thats more stable, which was actually designed for the PC, and not as a console port :D

[Ravenger]

Theres a significant difference between XP and Windows 7 - XP supports hardware sound acceleration, Windows 7 does not. Since lag seems to be at least partly caused by sound playback, perhaps that's why Black Ops performs better in XP.

[reactioN]

I can't believe that people would still consider using a horribly outdated OS, let alone reinstall it, just to play a game.



I never had slowdowns on xp or anything, and why is it horrible

i can still play the best mp fpses on good old xp without any problems

if you have slowdowns doesnt mean everyone has it , end of story

fun fact: most pc gamers still use xp

Not all "gamers" use XP.

XP has no support for my Triple-SLI. Can only use 2 GPU's in XP.

Thats not true.. with DX10/11 hardware mainstream more gamers are usin Win7. Check the steam survey reports. Windows 7 beat XP last year.

45% of gamers are using Windows 7 (32/64), 27% use XP (32 / 64). In fact more gamers are using Windows 7 x64 than using XP 32 and 64 combined now.

I play on windows 7.
My FPS isn't the problem. I don't know the exact numbers since i have never cared to check. Visually it feels ok to me and i have a system that is under two months old.

The issue is with stutters and hiccups every so often.

Shadows OFF makes things a bit better, but i still get stutters and random lockups. Usually at the start of a match or when i first shoot at someone.

So my question to you is do you still get the stutters under XP at all?

[Dabigbom]

So my question to you is do you still get the stutters under XP at all?

Minimum to none from what I have experienced.

I'm playing for almost a half a day now and I had no problems whatsoever apart from having a bit of stuttering when the match begins. But other than that it runs great.

As for the people with the whole "WINXP DIEDIEDIEDIE" bull♥♥♥♥, will you give it a rest? People are having major problems here with an outdated engine and have finally managed to get a part of their money's worth by doing this. Enjoy your game and we will enjoy ours.

I don't give a rats ♥♥♥, I don't have enough dough to fork up for some shiny new hardware and I have been playing games on this old bird for a long time now. Same with others here. So please, enough.

[GamerofRage]

Actually you don't need Windows 7 for modern games. All of those are just console ports, so they don't support DirectX 10 or 11.

Installing dirvers on a clean copy of XP right now... gonna see if the stutters are still present.

And btw, i prefer performance over the actual look of my system. So i don't really need the Win7's Areo to be happy.

[tet5uo]

Those of us who are surround-screen gamers with multi GPU setups and lots of system memory need win7 :)

XP supports up to 2 GPU's.
You don't really need more than 4GB of system memory, 32bit XP detects only 3,25 though. And X64 version is crap.

[Buer]

Yeah and everyone talking about how much better an OS Win 7 is. Do you realize that a dual boot takes little to no effort to obtain. Then you can play anything that runs better on XP on XP same goes for Win 7. When the time comes and you no longer need or want XP all you have to do is delete the partition it's on. And that is that.

I myself use Win 7 for most everything, except Black Ops and a select other few. Which I use XP specifically for, and nothing else. But THIS is the beauty of having a PC, versatility. To argue that Win 7 is supreme and that no one should be using anything else, just shows ignorance.

[MADDCENT]

i already have a dual boot but i dont really feel like having to shut down and boot up in XP every time to play black ops with normal fps :X

I roll with the times and like W7. XP is my past and so are those games I played with it. And since I run a i7 980x and 6GB running XP wouldn't benefit me. I don't have one PC in my home that runs XP anymore. And if in 2010 soon to be 2011 I need to run XP to play a game I don't want it. Like most I built my systems to take advantage of killer graphics and speed. If I wanted to stay in the old times I'd still be running my AMD X2 series CPU's.

Tryarch didn't disclose all the facts about this game. And as one poster was talking about a class action law suit well he now has grounds for it. I just want to see how many come and post about XP and how well it runs for them. If it's a large amount Tryarch then has some legal issues, and refunds should be given to those who want it.

Nicely written and completely understandable. The point I was trying to make is, it's not hard, time consuming and takes up very little space to run a dual boot setup with XP and Win 7. I like Win 7 too but I'm not going to throw out a game I payed good money for just because I'm biased against older operating systems. A class action lawsuit? Eh, I'm no lawyer by any means, but I'm sure the devs haven't given up and a patch will be out sooner or later. Plenty of games have come out over the years that take several, and I mean several, patches before they even start to look like a playable game. I've been PC gaming since the 80's and know from experience. Although there is a big difference in the times, as back then I could actually take the game back and get a refund or trade it in for something else. If the game somehow doesn't get patched up and a class action lawsuit goes through, then so be it. But I seriously doubt this game will stay as is and never recieve another patch.

Until then I'll just be playing without any problems by booting XP from startup rather than Win 7.

what ati driver do you ppls use, i have a dual boot system, so when i play in windows xp before the patch was released, it was infact even worse and it crashed ingame, not in menu, so i deleted it and boot back to windows 7 x64, and after the patch i didn't tested it on xp, now, yesterday i tested it and i saw an amazing increase in fps, but the thing is it still crashes,

[kai121]

Just posting to confirm this oddity, spent a couple of hours setting up a new partition and installing XP then updating to SP3, updated all my drivers for the XP boot and copied over my black ops, ran it and all the stutter was gone - even on a Domination Nuketown map (explosionville) I didn't even lag or stutter in the slightes (win 7 when it was explosion heavy it would lag slightly)

Setup:
Dual Boot Windows 7/XP
Duo Core E4500 2.2Ghz (OC'd to 3Ghz)
2GB RAM
GeForce 9800 GT
Realtrek HiFi Soundcard

For those of you who have issues setting up a dual boot I suggest a program called Easy BDC, as it sets up the boot options for you, sets out priorities ect...aswell, you just select what operating system you want when you start up (after 30 seconds defaults to primary OS)

(P.S. If you do install XP afterwards and can no longer access Win 7/Vista try this (enter everything inside comma's):
Start -> Run -> Diskpart
"List Disk" A list will show up showing Disks Find your main one

"Select Disk #" # being your disk number

"List Partition" Another lsit will come up, check your sizes and find the one with your main windows install.

"Select Partition #" # Being the number of your main disk

"Active" Will set that partition as the active partition

Restart and it should go abck to your main OS, had an issue the first time I did this where I didn't configure windows to allow me to select what I botted and these commands saved my ♥♥♥.

Wrong!!

The main cause of the problem is nvd3dum.dll(Nvidia WDDM D3D driver dynamic link library in Windows 7/Vista).Stutters arrive when this specific dll begin to use almost all of CPU resource(especial Dual Cores CPUs) while BO executable runs(U can check this by using Process Hacker freeware software and find the threads of BO executable).

The first and only member's thread of this forum that have mentioned also my findings is here (http://forums.steampowered.com/forums/showthread.php?t=1602160)!His thread is lying in the dust already:)

Why the game runs with zero problems on XP u ask?..bcs the driver architecture is totally different(there is no such DLL involved).Also U will ask why the hell other users with 2+ cores(minimum clocked @3GHZ) don't have stutter on Win 7?...bcs the executable threads(calls to WDDM D3D dll) are handled by all cores and the stutter is less to zero!

Here (http://img337.imageshack.us/img337/5511/codboidllethreadscomape.jpg) U can see illustrated my words ! ;)

This is applicable also for ATI users,bcs ATI also have sutch WDDM dll for Windows 7/Vista.

So bottom words:They must fix the way that executable calls this DLL in Windows 7/Vista!!!

Anyone that isn't agree with me can check by himself with opening BO exe and examine his threads on specific OS/CPU/GPU!!!

PS:About Audio stuttering!There are two threads that are responsible for the audio of the game - xaudio2_7.dll and wdmaud.drv,before the 2nd patch the priority of this threads was set to "-3" witch means below minimum.This was the game developers try to reduce the stutter but as all can see it was not enough.Also they also suffers from eaten CPU resource by WDDM dll witch leads to sound tearing/loop.

I'm thinking you're a troll, not sure if anyone can be as dumb as you..

I had to reformat because I initially installed the 260.99 drivers to see what FPS I get on a freshly installed 7.......... still ran as poor as your English.

So, I decided to install those Developer drivers people were claiming to fix the stutter.. well, I used Driver Sweeper (as per usual with getting rid of drivers) but as I was doing it, my power went out. I have no control over that, the joys of living on a US Air Force Base. Later on I tried to turn my computer on.. it bluescreened after the "Press any key to launch from CD", I literally had no control over what happened.

Again, a fresh 7 install (I did absolutely nothing wrong) still stuttered.

XP didn't.

I guess you didn't read all my posts. I'm not getting any stuttering in W7. The game is just running at a much lower framerate for me. It's still playable, no hitching or pauses or stutters, it's just a lot slower in the performance department. I did however experience the stuttering everyone talks about the first time I tried the game on XP but reinstalling the latest audio drivers fixed that completely.

[pyide]

Are you guys complaining about 40 fps? I get 18 at peak right now...

I prefer consistent framerates whenever possible. It drops below 30 in some maps and situations for me. If that's the max I got I would live with it, but depending on where I am on the map it will go from 60 (w/ vsync) to sometimes less than half that for no logical reason. It's hard for me to play with that kind of inconsistency and since I know I can get a solid 60 in XP it's obvious there is a problem there worth discussing and fixing, right?

If you are only getting 18 at the most you are either on an ancient PC well below the minimum requirements so you have no cause to complain so you complain about us complaining instead, or you are getting hit with the same problems we are and should want to see this fixed as much as we do.

I dont know why I would bother running this game in XP when it runs perfectly fine on my computer in windows7?I average between 90 and 130 fps,so how much more do I need?

I would assume this thread is for people who had problems running it in Win 7.

I guess you didn't read all my posts. I'm not getting any stuttering in W7. The game is just running at a much lower frame rate for me. It's still playable, no hitching or pauses or stutters, it's just a lot slower in the performance department. I did however experience the stuttering everyone talks about the first time I tried the game on XP but reinstalling the latest audio drivers fixed that completely.

I did read your post,U have Quad Core CPU as i see,I'm asking for Dual Core user here with W7,also U get performance (FPS) boost in XP bcs of same reason,that I have explained in my first post here.U can gain about the same performance like in XP i guess by clocking up your CPU above 3GHz,give it a try if U R familiar with such things;)

for what its worth,

I just set up a dual boot. first tried black ops on my Win 7 64bit install, stutter madness.

then i installed Win Xp...stutter free. smooth as silk.

Confirmed. Black Ops will run literally twice as good on a 7200 RPM under win XP versus a SSD running Win 7.

Confirmed!

Dual boot Windows XP 32bit yields slightly higher frame rates with two old 3870's Crossfired than Windows 7 64bit. With a fresh Windows 7 I had dips in maps as low as 30 FPS in XP it is never under 40's.
