[FIX] Call of Duty: Black Ops - Game Freeze / LAG FIX!

[Rugaal]

1. Open Console (`)
Type cl_maxpackets 100
Close Game.


2. Right click on Black Ops Multi in steam games
Go Properties -> Updates -> Untick Enable steam cloud sync.

If the above doesn't work try the following..

3. Steam > Settings > In Game > uncheck “Enable Steam Community In-Game”

*** Also could try another methods, like one of these:

Console Commands:
Draw your FPS on screen:
/cg_drawfps 1
Draw your Lagometer on screen:
/cg_drawlagometer 1
Max FPS command:
/com_maxfps 0

Others:
/cg_fov "80" (GAMEPLAY)*
/com_maxfps "125" (FPS)*
/snaps "30" (REGISTRY)*
/cl_maxpackets "100" (REGISTRY)*
/cl_packetdup "2" (REGISTRY)
/rate "25000" (REGISTRY)
/sm_enable 0 (FPS)*
/r_drawdecals 0 (FPS)*
/cg_drawFPS "Simple" (FPS)
/cg_brass "0" (FPS)
/r_multigpu "1" (FPS)
/r_cachemodellighting "1" (FPS)
/r_cacheSmodellighting "1" (FPS)
/cl_mouseaccel "0" (MOUSE)

Untested:
/r_rendererPreference "Shader model 2.0" (FPS)
/r_vsync "0" (FPS)
/r_smc_enable "0" (FPS)
/r_rendererPreference "0" (FPS)
/r_skincache "1" (FPS)
/cg_blood "0" (FPS)
/com_hunkmegs "512" (FPS)
/r_drawsun "0" (FPS)

Now Type In Console:
/vid_restart

Notes:
*CG FOV :: Field of view, where the value is the angle of the circular arc that is displayed
on your screen. High values will make the game appear "fisheyed".

*MAX FPS :: This command limits your maximum FPS. You may ask why you would want to do this,
and the answer is that it will help the server from having lag confusion when your frame rate
has a sudden rise or fall. Run a timedemo, collect your average FPS and use that as the limit
for when you play on-line.

*SNAPS :: This is possibly the most important setting for getting a good connection.
Snaps setting determines how many updates you recieve from the server. 20 to 30 for
56K connects in quake series 40 for high speed internet im sure the same for cod. (30 is fine).

*MAXPACKETS :: This setting puts a limit on the maximum amount of packets that can be sent to
the server via the client. This setting is useful for people with slower modems. Obviously we
all have high speed connects so set to at least 100. Lower maxpacket settings i.e 30 lowers ping
on screen but at the cost of registration.

*SM ENABLE :: Turns off unique Shadows ingame, it boosts FPS more than most commands.

*R DRAWDECALS :: Turns off details on walls and objects, however Punkbuster will kick you off for this at this time.

Other way is to change your config_mp.cfg in your C:\Program Files (x86)\Steam\SteamApps\common\call of duty black ops\players\config_mp.cfg and change values for these settings:

r_multiGpu

This should only be enabled if you have multiple graphics cards or a graphics card with multiple GPUs. If you don't have multiple GPUs, don't know what this means, or are having issues with your MultiGPU solution, please set this to "0".

r_multithreaded_device

This setting should be enabled for EVERYBODY as the minimum requirements for Black Ops clearly states that you need a multithreaded (multicore) CPU to run the game. However, some people have noticed that by setting this to "0" some of the skipping lag is relieved. Test this out only as a last resort.

r_vsync

VSync prevents screen tearing. If you don't know what that is, just set it to "0" because you probably don't care anyway. Otherwise, VSync usually doesn't have any negative performance issues with today's graphics cards. However, there may be a few performance issues linked to VSync with the current release of Black Ops. Try setting this to "0" for compatibility.

r_blur_allowed

This setting enables Blur shader effects. If you have a strong shader card, this setting may be negligible. Otherwise, just go ahead and set this to "0".

r_distortion

This setting enables Distortion shader effects. If you have a strong shader card, this setting may be negligible. Otherwise, just go ahead and set this to "0".

r_dof_enable

This setting enables Depth of Field shader effects. If you have a strong shader card, this setting may be negligible. Otherwise, just go ahead and set this to "0".

r_glow_allowed

This setting enables Glow (HDR?) shader effects. Normally, this should have a negligible performance impact. HOWEVER, this setting seems to be buggy! Performance improved DRAMATICALLY when I set this option to "0".

rate

Rate is the rate at which the client sends packets to the server. If you set this too low, below 10000 or so, you run the risk of sending insufficient data to the server and lagging out. Set this too high, above 50000 or so, and you run the risk of flooding your connection to the server. This setting should be adjusted according to your connection speed and may take some fine tuning.

cl_maxpackets

This setting controls how many packets the client will hold to ensure packet transmission. If you set this setting to low, below 20 or so, then you run the risk of being disconnected prematurely. If you set this setting too high, above 150 or so, then you run the risk of continually resending redundant data and lowering your ping (or worse, getting choked). This setting is very hard to tune because it depends on so many factors beyond your own connection. Most people have found setting this to 100 is a good compromise for most servers.


Some further technical notes:

It seems that the issues plaguing PC Multiplayer are two fold.

First of all, poor CPU management is causing bottlenecks, especially with what seems to be thread context switching. This causes the system to hang intermentently as data is switched between the cores of your CPU.

Next is poor management of the netcode. The netcode must be shared with the game engine in such a way that when the CPU hangs, no data is being transmitted to or received from the server, causing packets to timeout in both directions and LOADS of redundant data being transferred between all players.

So fixing the lag on your computer should help to alleviate the load for everybody else on the server and give all around better game play.

Also note that the above is just observation and speculation from an experienced programmer. I have, obviously, not seen the source to Black Ops, but because of how the application behaves, these are my most educated guesses.

Try what I mentioned above and let me know if you find anything else that is of importance to the current state of multiplayer performance.

Good Luck and Good Fragging!

Rugaal i've played with the with config file alot and it's not going to help in multi.
The game is faulty when it comes to CPU usage.

[Rugaal]

UPDATED!

[Rugaal]

BUMP, so every1 can fix it faster!

[jakal1976]

Yeah we'll see a difference when it gets patched,let's hope soon enough

[o'dium]

This isn't a FIX. This is a work around. You don't fix a flat tyre on a car by just removing it...

[ownu00]

anyway you can make this some kind of auto config file so we don't have to write all of this every time.

[skjusto]

Is this working for anyone?

[Rugaal]

you dont have to write it everytime, if you configure it in your config_mp.cfg file, it will stay like that on next game startup ...

[EagleDM]

Did someone try to "FORCE" the full 3D speed profile on ATI catalyst drivers and NVIDIA?, because by the looks of the problem it seems to be that 3D rendering is hardly used and driver thinks it's in low power 3d mode, from that comes a very laggy experience.

I say this because on 4870 videocards lag is not present, but the card stays on it's low power 3D clock, which is 500 and is not too low, but for newer cards, low power is very low and maybe is creating the problem.

[lightbeats]

I've changed a few settings in game, in config, in nvidia control panel... all they have done is ease the issues and still I am only still playing because this is new and exciting. If this was a game i'd played before I would not be playing it, right now I am only trying to get my money's worth.

I am now (after tweaking a few setting's) experiencing stuttering especially when I come into close quarter combat with enemies, serious hit detection/lag issues, all with the graphics set low.. on a game running the same engine I could run MW2 on maxxed out with high fps.

[Ex0duS_5150]

Who ever is in charge of making a patch should get there azz in gear and get it out already.. We waited patiently for this and now its unplayable.. The way the consumer just gets f'ed over on a regular basis in the video game world is just depressing now a days..

Don't blame the developers; blame the user that does not know how to optimize their own systems. I have a very old system and it works flawlessly.

However if want a quick boost in FPS, disable aero & desktop composition inside vista / windows 7.

No no no. You do blame the developer, when there is something wrong with their app. There is something wrong with their app. No game should max out both of my CPU cores. That is the problem. We should be able to install any game on any system and have it just work. This game, however, requires the mother of all tweaking on most systems. No. Just no. Don't talk about things of which you do not know. My system runs anything I throw at it, I don't need to do any tweaking, I need to wait for a patch.

I dont know jack about scriptings or whatever you call these things. I dont know much about the OS nor anything alike it. I know how to play games and I enjoy playing games. Alot. I dont want to have to go in and type alot of stuff into some consol that I dont know what it means or what it does to my software. I dont think I should have to. Thus I am patiently gonna sit and wait for an update or patch. SP works without issues atm for me so I'll do that until "someone" fixes the MP.

I believe Aero is disabled by default as soon as you enter a full-screen DirectX-enabled application (i.e. Black Ops). But good advice nonetheless.

[osigurac]

disabling the steam cloud for the game and overlay removed most of teh lag for me.

[Exinjeru]

I ran comparison tests with Black Ops vs Modern Warfare 2.

The stupidity is apparent immediately

MW2: 1080p, high textures, medium effects detail, 2x AA, 45FPS

Dual Core CPU 75-90% usage
System RAM 1 gig allocated during play
ATI GPU 100% usage, 65 degrees C
VRAM 100% usage

Black Ops: changing settings has little to no effect on performance, 15-25 fps, sudden stuttering of 1 FPS even in menus.

Dual core CPU 100% at all times, even during menus or when the game is paused.
System RAM 300 megs allocated during play
ATI GPU 8-15% usage, 45 degrees C
VRAM 0% usage

It's pretty clear that the game is handling multicore CPUs poorly, and it's just ignoring GPUs completely.

[Rugaal]

I hear more and more about steam cloud doing alot of lag also, so possibly turning off steam cloud and ingame chat via steam>games>right mouse click on cod:bo>uncheck steam cloud and ingame chat would highly decrease your lag!

[Rugaal]

1. Open Console (`)
Type cl_maxpackets 100
Close Game.

3.Steam > Settings > In Game > uncheck “Enable Steam Community In-Game”

[b0sco]

Doesn't fix the 'Connection Interrupted' every few seconds into an MP game, changing maxpackets even made it lose connection faster.

[CatNoise]

Making the game look ugly don't fixes anything.

[dekeholden]

Instead of having to type that all in console, can't you make a file so it automatically loads?
Like autoexe.cfg in Tf2?

[Exinjeru]

Yeah you can put it in the .cfg file in the player directory. But tweaking isn't going to help when the game isn't even using your videocard at all, that's why people are getting such poor performance.

If the game just used your CPU and videocard properly it would run exactly like MW2, it's the same engine.

Havn't got problem like you mentioned, only sometimes it drops off server with message 'Server session no longer available' or something like that.

[explodingape]

i have most of the problems you guys have, but for some reason it runs zombies strangely well. i guess that can keep me busy until this ♥♥♥♥ gets fixed.

[Nick_000]

ATI 4850 1 GB

4GB ram

... runs all games maxxed out, no problems but black ops.. laggggg even in singleplayer and mutliplayer !!

This is normal right ? i mean it lags every 1.5 secs... and about every 5 mins it big lags it so it freezes COD BO for 1 min..

If by 'normal' you mean 'experienced by a pissload of the community' then yes,

It has to do with how Black Ops is using the resources available to it (read: poorly)

[Nick_000]

So i have lowered the piority of steam.exe and it makes it better.. what else can i do.

p.S. i disabled steam overlay + steam cloud.

the game runs like mw2 for me now :D MANY THANKS!!!

SURE???

Also try

/demo_enable 0

To my understanding this stops the "Theatre" recording

hey guys. i ive in hungary in eastern europe, and i want to play online, but i dont have enough money to buy the BLACK OPS due i'm a student in a poor family. :( please if u can gift me the game, (my steam id: doktorur87) i will be so happy, thanks guys and play fair! tamas

sorry for the off topic

[splodead]

I tried everything including /snd_restart and setting to a low resolution, low graphics, no brass, no glow no blur ect ect. maxpackets 100, everythign suggested.

My max fps went up, but it still drops frequently to below 30 or 20 or lower, making it unplayable.

so overall no change.

Also my single player worked at one point, but right now it likes to blur the screen when i aim down the sight (problem with depth of field maybe?) and it likes to explode the HDR to make it super annoying.

I can confirm... this did not fix my FPS drop. I mostly average 80-120 FPS, but falls to 20-30 during stutter. Nice try though. Hope it worked for some.

Wow. First off. Stop trolling. Count yourself the lucky few if what you are saying is accurate. Second don't look down on people because they are having issues with the game. I have a very beastly machine because I want to play newer games without hiccups during multi. To sit there and logon to a forum just to be a ♥♥♥♥. ♥♥♥♥ you.

Hell. ♥♥♥♥ your parents for swapping fluids. You degenerate waste of an excuse of a human. If you are older than 18 I will be even further amazed.

[placebonation]

I'm not sure many people on this forum have reading skills. Or comprehension. CPU overload. Vid card not being used. Making changes to the *.ini does nothing. It may lower the load on the CPU but it's not a fix. and Ruggal/Rupal stop the 'bump!' your fix may help on some level but far from addressing the actually problem. Once the game is patched correctly yes your config will address systems that are under the sys requirement.

[Rugaal]

bump.

[MulkyBros]

Thanks for the help Rugaal, unfortunately it seems alot of servers are having lag spike issues as well. Plus I still get the router crash after I join the server. Hopes that the game gets patched or I'll just have to look to AS:brotherhood on the 360 and stick to my old steam library.

I don't know... i have tried all suggestions in these forums and although some slightly improved the issues, for the most part nothing is working.
I guess my computer just can't handle this game. Funny thing is that it looks beautiful on my son's Xbox 360 and the Xbox has much less in terms of hardware specs than my PC does. I thought this was a console port? It should look and play much better on my PC and it doesn't...

[Rroff]

snd_restart does help a bit - I find if I do it at the start of each map and about mid-way through each map then the really bad juddering doesn't happen that much tho overall performance is still far from ideal.

Testing demo_enabled 0 now

EDIT: demo_enabled makes no difference.

[lartmoney]

I guess my computer just can't handle this game.

ahh cmon, this game (?) is broken , don't you see it ?
i have a high end rig and it's unplayable since the release.
just waiting for patch 3....

[RoGalik]

game have more and more lags.. it's unreal..
Thing which is annoying, it is an eternal connection to the server..
in multiplayer, some freeze..
The game needs to be expanded - is the patch..
Still wait..

[god_og]

It is after all a router problem... I am checking on how to fix it, ... DMZ disabled, setting the right ports open for BO and Steam did not solve the issue and switching the UPnP on/off is useless as well.

The rig in the game is in the way it goes through the router and that it is not capable of doing so properly. Maybe they will fix it and Id be happy if they do, cos there are games which can manage to get the connection right (as MW2 for example)

I say this because on 4870 videocards lag is not present, but the card stays on it's low power 3D clock, which is 500 and is not too low, but for newer cards, low power is very low and maybe is creating the problem.

That's interesting. I have 4870x2 2Gb RAM and i use FORCE for overdrive, AA and AF since then it should bypass the default game settings. I checked and my GPU and memory frequency do not drop to 500, they stand at 750/900 MHz. However, in my case the problem is that even tho i have 60fps stable 90% of the time, on most maps there are areas where my fps drops to 50+ and on some even to 40+. The upcoming patch HAS to fix this cuz i don't wanna play like that.
If you meant something else by "Full 3D profile", by all means share it with me so that i see if there is anything more i can do remove those FPS drops.

*SNAPS :: This is possibly the most important setting for getting a good connection.
Snaps setting determines how many updates you recieve from the server. 20 to 30 for
56K connects in quake series 40 for high speed internet im sure the same for cod. (30 is fine).


r_multiGpu

This should only be enabled if you have multiple graphics cards or a graphics card with multiple GPUs. If you don't have multiple GPUs, don't know what this means, or are having issues with your MultiGPU solution, please set this to "0".

r_multithreaded_device

This setting should be enabled for EVERYBODY as the minimum requirements for Black Ops clearly states that you need a multithreaded (multicore) CPU to run the game. However, some people have noticed that by setting this to "0" some of the skipping lag is relieved. Test this out only as a last resort.



Good Luck and Good Fragging!

I changed just these three settings and my game is running like butter now. Thanks so much. and FTR, I had to change multithreaded to 1. For whatever reason, it was set to 0.
Either way, thanks a ton. Game looks and runs like it should have out of the box!

See if Punkbuster A svc is running. If it is kill it.

That fixed it for me.

Black Ops uses VAC.

[wisertime]

I reset rate to 3000 for some reason (one of these other fix threads) thinking the server side must have been the 25000...I'm going to try swapping it back. I think that is what caused me to lag again. Thanks.

I can attest multi GPU makes things worse if you only have one. Again conflicting theories.

Black Ops uses VAC.

YES BUT THE PROCESS IS STILL RUNNING ON ANY SYSTEM THAT HAS A GAME INSTALLED THAT USES PUNKBUSTER!!!!!!!

I have verified this on my system. Start Punkbuster....lag....stop punkbuster no lag!!!

This worked 100% for me. MP use to freeze within 5min from starting play. I tried what others suggested in the forums but they did not solve the problem.

I completely removed the GPU drivers and all its supporting software, restarted my PC and then installed the new version, restarted and tested.

The PC has not frozen up once since that, and that was 36 Hrs ago.

PC Spec: AMD Phenom 2 - 3.2Ghz, 4Gig DDR2 Dominators, Asus ATI 5850 1Gig DDR5 running Win 7 x64bit. ATI drivers 10.11.

same problem here, i m goin' crazy >.<

Not yet patched glitch with freezes ?

[M I C R O]

lol I didnt believe the whole multigpu and core command for a month, but i tried it 2 weeks ago and i havent crashed since.

[dade_kash_xD]

1. Open Console (`)
Type cl_maxpackets 100
Close Game.

2. Right click on Black Ops Multi in steam games
Go Properties -> Updates -> Untick Enable steam cloud sync.

If the above doesn't work try the following..

3. Steam > Settings > In Game > uncheck “Enable Steam Community In-Game”

*** Also could try another methods, like one of these:

Console Commands:
Draw your FPS on screen:
/cg_drawfps 1
Draw your Lagometer on screen:
/cg_drawlagometer 1
Max FPS command:
/com_maxfps 0

Others:
/cg_fov "80" (GAMEPLAY)*
/com_maxfps "125" (FPS)*
/snaps "30" (REGISTRY)*
/cl_maxpackets "100" (REGISTRY)*
/cl_packetdup "2" (REGISTRY)
/rate "25000" (REGISTRY)
/sm_enable 0 (FPS)*
/r_drawdecals 0 (FPS)*
/cg_drawFPS "Simple" (FPS)
/cg_brass "0" (FPS)
/r_multigpu "1" (FPS)
/r_cachemodellighting "1" (FPS)
/r_cacheSmodellighting "1" (FPS)
/cl_mouseaccel "0" (MOUSE)

Untested:
/r_rendererPreference "Shader model 2.0" (FPS)
/r_vsync "0" (FPS)
/r_smc_enable "0" (FPS)
/r_rendererPreference "0" (FPS)
/r_skincache "1" (FPS)
/cg_blood "0" (FPS)
/com_hunkmegs "512" (FPS)
/r_drawsun "0" (FPS)

Now Type In Console:
/vid_restart

Notes:
*CG FOV :: Field of view, where the value is the angle of the circular arc that is displayed
on your screen. High values will make the game appear "fisheyed".

*MAX FPS :: This command limits your maximum FPS. You may ask why you would want to do this,
and the answer is that it will help the server from having lag confusion when your frame rate
has a sudden rise or fall. Run a timedemo, collect your average FPS and use that as the limit
for when you play on-line.

*SNAPS :: This is possibly the most important setting for getting a good connection.
Snaps setting determines how many updates you recieve from the server. 20 to 30 for
56K connects in quake series 40 for high speed internet im sure the same for cod. (30 is fine).

*MAXPACKETS :: This setting puts a limit on the maximum amount of packets that can be sent to
the server via the client. This setting is useful for people with slower modems. Obviously we
all have high speed connects so set to at least 100. Lower maxpacket settings i.e 30 lowers ping
on screen but at the cost of registration.

*SM ENABLE :: Turns off unique Shadows ingame, it boosts FPS more than most commands.

*R DRAWDECALS :: Turns off details on walls and objects, however Punkbuster will kick you off for this at this time.

Other way is to change your config_mp.cfg in your C:\Program Files (x86)\Steam\SteamApps\common\call of duty black ops\players\config_mp.cfg and change values for these settings:

r_multiGpu

This should only be enabled if you have multiple graphics cards or a graphics card with multiple GPUs. If you don't have multiple GPUs, don't know what this means, or are having issues with your MultiGPU solution, please set this to "0".

r_multithreaded_device

This setting should be enabled for EVERYBODY as the minimum requirements for Black Ops clearly states that you need a multithreaded (multicore) CPU to run the game. However, some people have noticed that by setting this to "0" some of the skipping lag is relieved. Test this out only as a last resort.

r_vsync

VSync prevents screen tearing. If you don't know what that is, just set it to "0" because you probably don't care anyway. Otherwise, VSync usually doesn't have any negative performance issues with today's graphics cards. However, there may be a few performance issues linked to VSync with the current release of Black Ops. Try setting this to "0" for compatibility.

r_blur_allowed

This setting enables Blur shader effects. If you have a strong shader card, this setting may be negligible. Otherwise, just go ahead and set this to "0".

r_distortion

This setting enables Distortion shader effects. If you have a strong shader card, this setting may be negligible. Otherwise, just go ahead and set this to "0".

r_dof_enable

This setting enables Depth of Field shader effects. If you have a strong shader card, this setting may be negligible. Otherwise, just go ahead and set this to "0".

r_glow_allowed

This setting enables Glow (HDR?) shader effects. Normally, this should have a negligible performance impact. HOWEVER, this setting seems to be buggy! Performance improved DRAMATICALLY when I set this option to "0".

rate

Rate is the rate at which the client sends packets to the server. If you set this too low, below 10000 or so, you run the risk of sending insufficient data to the server and lagging out. Set this too high, above 50000 or so, and you run the risk of flooding your connection to the server. This setting should be adjusted according to your connection speed and may take some fine tuning.

cl_maxpackets

This setting controls how many packets the client will hold to ensure packet transmission. If you set this setting to low, below 20 or so, then you run the risk of being disconnected prematurely. If you set this setting too high, above 150 or so, then you run the risk of continually resending redundant data and lowering your ping (or worse, getting choked). This setting is very hard to tune because it depends on so many factors beyond your own connection. Most people have found setting this to 100 is a good compromise for most servers.


Some further technical notes:

It seems that the issues plaguing PC Multiplayer are two fold.

First of all, poor CPU management is causing bottlenecks, especially with what seems to be thread context switching. This causes the system to hang intermentently as data is switched between the cores of your CPU.

Next is poor management of the netcode. The netcode must be shared with the game engine in such a way that when the CPU hangs, no data is being transmitted to or received from the server, causing packets to timeout in both directions and LOADS of redundant data being transferred between all players.

So fixing the lag on your computer should help to alleviate the load for everybody else on the server and give all around better game play.

Also note that the above is just observation and speculation from an experienced programmer. I have, obviously, not seen the source to Black Ops, but because of how the application behaves, these are my most educated guesses.

Try what I mentioned above and let me know if you find anything else that is of importance to the current state of multiplayer performance.

Good Luck and Good Fragging!

This is by far the most indepth and thought provoking 'help' thread for fixing lag/stutter in Black Ops PC. I appreciate you taking the time to not only post your results but for also shedding some insight as to what is actually causing this lag.

For me, the game ran fine from launch (11/09/10) up until the release of the 12/14 patch. The 12/14 patch was the one that removed 16xCSAA and was the first to truly optimize performance for dual core machines. After this patch, I started experiencing the lag/stutter.

It took me over 3 weeks to find the solution but for me, the right answer was in changing the mipmap settings in config_mp.cfg. I still do have some annoying graphical glitches in this game that I still deal with, however the stuttering is completely gone. Like on the map "Nuketown", the large patch of grass in the backyard of both houses has a black but opaque grid-like look with yellow flashing hues embedded. The only thing that helped was disabling AAA in ATi CCC. Do you know what this is?

Here's an example:
