I was wondering if "portal bumping" was considered a OoB trick because I thought it was not but someone tells me it is, technicaly both portals and Chell all stay in the map so it is not OoB, but if it is considered out of bounds that makes my entire speed run time worthless to me, I was proud to say that I was #1 in non-OoB consel run but if my portal bumping is considered OoB I would be lieing to people (even though it only saves me 30 seconds and I would still be #1 in non-OoB the leaderboard time will stay and that would not be my correct non-OoB time) so if any portal speed runner can tell me, is portal bumping considered OoB?

Portal bumping is perfectly fine if you say within the map. It is only when the player bounces outside the map and is no longer in the valid play area. Just like in sports and other games that have boundaries, if the player goes outside of them, the player is no longer in the field of play.

When inside the map, pretty much anything you can do is acceptable except using performance enhancing scripts, utilities, or hacking the game itself. Even leveraging other interesting glitches, or suspected glitches, are fair to use as long as you remain within the map\boundaries. The game overall is about being creative, thinking outside the box, and solving problems in unique ways, therefore there practically are no rules about what you can't do or use.

Thank you for the reply, I thought so but the other guy was content on saying it was an OoB trick. ;)

What about if you went through one of the offices that you technically aren't supposed to get into? Specifically, the one in Chamber 15. It has a small leak in the corner where the two windows meet and you can shoot a portal through, then use portal bumping to get back out in the next hallway. Personally I don't feel that it is OoB since the room is fully textured and such, but it wasn't an intended play area so it may be considered OoB by the general population.

I can never seem to get that bump to work correctly on the xbox so I don't use it but I don't think it is OoB because you are still technicaly in the map and not out in the blackness, but that is just my oppinion. ;)

As long as you stay in the map, it is perfectly fine. You're still, more-or-less, inside the virtual world.

Just a question nrnobel, I was wondering what your speed-run record is? (and I am assuming it is a non-OoB record)

Well, speed runs aren't my particular specialty, but the last time I did one it was around 35 minutes. During that run I died a couple of times in chamber 11 attempting to use the shortest\risky path (Chamber 11 run (http://www.youtube.com/watch?v=nX0EnZqb-eA)) and I ended up in the toxic waste both times... lol. Figured I lost 1-2 minutes in chamber 11. I will give it another shot and see how I do. I figure if do well, my time would be around 30 minutes.

On youtube there are some very amazing runs, and a few of them are questionable. Clearly some are using script and other sorts of performance enhancing tools that give them the ability to do amazing things. I suspect that Valve intentionally broke .dem files because pre 2009, .dem files were used to create fake speed runs and other sorts of superhuman feets that now are nolonger possible since .dem files nolong work with Portal (Thank you, to whom ever decided to break .dem file recording... ;) )

When I do my single segment runs I do not use that trick I do that chamber the normal way, but I usualy do multi-segmated runs so if I mess up I don't have to restart the entire game. ;)

Well that is impressive. I can't even imagine how that might be possible if you are staying within the map. If I were to break 30, or 25 with a hell of a lot of practice, that would be pretty good. I'm wondering if there is some differences between the PC version and the 360. I've have the 360 version too (and PS3), so I'll have to fire it up again.

Are there any youtube videos that are similar, or come close to, your speed run times (non-oob)? I want understand what being done to get such fast times. All the speed times I have seen are OOB runs, and those don't interest me at all because they are OOB. Personally I hope with Portal 2, OOB play becomes instant death like many other games, but that might tick off a lot people who love that type of play (which is why I think the Portal team didn't make OOB instant death).

There is only one difference between the versions, the level after you get the full gun you can shoot the wall through the door from the switch. What I did to get all my shortcuts was watch alot of videos and use the shortest way at each part and I also added a bit myself to get it even faster the only thing is that I can't seem to get all the computer bumps to work on the xbox like the one in 15 and a few others, I also can't speed backjump like in some of the videos (well you can't anymore either) so because of that I had to improvise sometimes in my runs to make it work for me. ;)

That has nothing to do with this topic, but I do like how you take the broken turret to the cake room. (You should have had both the cube and the turret in the picture, and you should have also put some more live turrets in) ;)

With a bit of focus, I got time down a little bit. For chambers 00-18, my time is 17m:17s. which is better than I thought, and there is still room for improvement because its still far from being perfect. Like most people I've spend very little time replaying chambers 00-10, so I suspect I could improve my times earlier in the game, but those chambers are where the player has only one Portal active with the Portal gun, thus limited options to improve speed times.

Chamber 19 is long and will add a lot more time to my 17 minutes. I've played it a lot so know most of the short cuts already. However, I've never spent much time replaying the final GLaDOS battle and I don't use any of the tricks I've seen on youtube where people get all the modules before the timer even starts. I've always handled it the standard way which means it takes me at least 3-4 minutes after door slams shut to destroy GLaDOS.

I'll post a segmented youtube video once I get something respectable.

Krogglidor
03-21-2010, 01:01 AM
I use the glados turret way because you are right it saves about 3 minutes, and from the top of my head my records for 13-18 are 12, 8, 36 (not sure about this one), 31, 56, and 57, I will update this post tomorrow when I check my records for the chambers. ;)

Can someone tell me what portal bumping is?

nrnoble
03-21-2010, 03:56 AM
Here is simple example: Chamber-15 Portal bump (http://www.youtube.com/watch?v=XgEwAOSc4U8)

It is where you "bump" a portal to the other side of a wall or barrier of some kind. Often it results in a short cut through the game. In some cases you will find yourself outside of the map, often referred to OoB (Out of Bounds).

There are only a handle of locations in the game where you can do it. Some are easy to find, others are found through experimenting and analyzing the the game. The one is the video is an easy one to spot because the floor both sides of the barrier is a portal friendly surface. If the surface on either side is resistance to portals, then you can not portal bump.

Krogglidor, what route do you use in chamber-16? Do you use the 13-20 second speed run route as seen on you tube, or do you use a different route. Not all of the ones I've seen on youtube are real, some are faked runs recorded at a very slow frame rate, speeded up to look real. The route that takes between 13-20 seconds does appear doable, but I question how repeatable it is. If a person can only repeat it a small percentage of the time, then its not a realistic speed route.

This is the route (Chamber 16 speed run (http://www.youtube.com/watch?v=6KqgXaE8LQA)) that I've been using because my times are constistantly between between 40-45 seconds depending on mistakes make; practically no chance of death. I suspect I could break 35 seconds on this route with a bit more practice and refinement. The runs in the video are just random (flawed) practrice runs.

Krogglidor
03-21-2010, 08:47 AM
I could never do the second bump on the 12 second run, that bump that you do in he video I have never seen before and I should try it out, I have been going all the way around to get my 31 seconds and that bump could save me a good 15 seconds. ;)

nrnoble
03-21-2010, 09:29 AM
A lot of of how I do things were figured out before I started watching youtube, so while a lot of what I do is similar to what others have discovered, most is not just copy\paste from what I have seen. The advantage of doing without too much outside influence is that I think about how the game works and consider the many possible options. Those who just mimic what is on youtube, don't find anything new themselves because they really don't understand how the game ticks. In the case of the path I take in Chamber-16, when doing the achievement runs, I looked at all the possible locations within the map where portal bumping was feasible (two portal friendly walls\ceiling separated by a single wall) and I found the one that led into the room with all of the cubes, which of course eliminates having to go the longer way around.

It has been debated if portal bumping was intentional by the dev team. Only they know the for certain. I personally don't think they designed the game with portal bumping, but I suspect they found it before it release and left it in the game. There are many places throughout the maps where it appears they have intentionally block portal bumping (ie third chamber of Chamber-15 where the player does a fling), so it leads me to believe they wanted to make sure at certain locations in the game players couldn't use it as short-cut.

Krogglidor
03-21-2010, 11:35 AM
well I did the same thing and tried to figure out a route for myself then I looked at youtube and pretty much every chamber had a better route than mine the only place I can think that I had a better route was the escape I had a couple routes that saved me only a few seconds. One of the reasons that youtube had better runs was I did not know how to bump before youtube so therefore had to do all the chambers normaly, I did get gold on every chamber before I looked at youtube though. ;)

Edit: I looked at my times and they were all right except for 15 (12, 8, 38, 31, 56, 57) and I will post some video's that use some of the same routes I do give me a second.

Chamber 00, 04, 05, 08, 11, 12, 13, 14, 15, 16, 17, 18, 19

http://www.youtube.com/watch?v=Zwnfky3FH30
http://www.youtube.com/watch?v=fWt_cq1IHhY
I use almost the same route as this guy but without backjumping, and adding my own stuff in a few places to make it faster in Chambers 00, 01 (not much different you can do in the first 2), 02, 03, 05, 06, 07, 09, 10, 11, 12 (in this chamber on the xbox you can shoot the wall through the door from the switch), 13, 15 (I use a bump for the first force field instead of jumping through, and I can't get that one bump to work so I put the orb in and do the rest the same), 17, the second part of 19 (escape 00 I think), the last part of 19 (escape 02? the one with glados)

Chamber 08 I use the way where you jump off the block

http://www.youtube.com/watch?v=mSvrp_bQ7Bc
I do 14 sort of like this (I can never get the 4 second way to work)

http://www.youtube.com/watch?v=LGIQA6J1uhU
for chamber 16 I use a way kind of like this (but using the 1st bump and clearing the room with the 3 turrets, will probably switch to your way ;))

http://www.youtube.com/watch?v=W6qWWUa6GXA
for chamber 18 I use this way

nrnoble
03-21-2010, 10:26 PM
http://www.youtube.com/watch?v=W6qWWUa6GXA
for chamber 18 I use this way

Do you do it exactly this way from start to finish. If not what do you differently? I have seen this video before and I can't even come close to doing a couple of the moves. The first hard move I have not been able to do even once at full speed; one portal in the ceiling and the other in the wall. The only way I have been successful at doing that move is slowing down the game 500%, and even then the percentage of being able to hit the platform with a downward shot is extremely low, so low it is more random luck than skill even when slowed down to 500% of normal game speed. If it is doable, then I am missing something I had not considered doing.

To be specific, here is part that I asking about. http://www.youtube.com/watch?v=XvyzJJ890qs This video is played back at the same rate it was recorded at, and painfully slow, but it is the only way I have ever been able to do it.

Here is how I do the first hard section; it is similar and takes a 3-4 seconds longer, but I can do it 80% of the time without dying: Chamber-18 Least time (71 seconds) (http://www.youtube.com/watch?v=fZ2VYXI6vXo)

Krogglidor
03-21-2010, 11:10 PM
You have to aim exactly at it before you start falling because it is near-immpossible to aim sidways while falling, I don't always use that way since it is quite hard, I usualy just fall the the platfor below the top portal then aim at the ceiling of the next platform and put two portals on the ground to fling up, but the way in the video saves a good 8-10 seconds from the way I usualy do it.

nrnoble
03-21-2010, 11:41 PM
Do you jam the door open with wall camera? I've yet to have much success with that even during non speed runs. Getting the camera to lean against the door just right is also something that appears to have a very low percentage of success (at least for me). I have done it a few times, but my success rate is no better than 5% for each attempt to lean it against the door at the right angle, so I take the longer route. No doubt if I spent a week just doing countless speed runs through 18, recording all of my attempts, I probably could come up with one speed run video where I accomplish both in the same run. :) Everything else in the chamber is pretty standard\easy stuff... However, with that said, at one time I thought all the Gold achievements were unrealistically hard until I spend the time\effort\practice figuring out how to do them all, and in all cases I eventually figured out ways to exceed the Gold achievements requirements.

Edit: I think the 4 second speed run in Chamber-08 is a bit of magic trick which is no longer possible since Valve patched the game over a year ago. At one time, those gaming magicians would record .dem files at a very slow frame rate, then play them back at regular speed, so instead of having 1 ms to perform an amazing move at regular speed, they slow the game down so they had 1 second to do the same super human feat. Played back a regular speed, the impossible is made to appear possible.... ;)

Krogglidor
03-22-2010, 01:32 AM
What I do for the camera is put the portal low enough to jump through and just high enough that the top of the portal hits and knocks the camera off the wall and I catch it while it falls to it is standing up properly I then run into the door with it just enough so the door pushes the top of it up so it is leaning on the door, I have gotton the 4 second chamber 14 run once or twice, but it is so hard to do and takes such a long time to do that I take the 4 second hit to my time. (hope what I said helps I am not that good at explaining things ;))

nrnoble
03-22-2010, 10:25 AM
LOL... I have no problem understanding your explanations. Hell, compared to some of 'texting' gibberish that gets posted, you're posts are extremely literate and easily understood. :)

Thanks for those other links. Not seen some of them. Clearly I have a lot of room for improvement. I'll never be quite that good because my eye\hand coordination is just a tad slower than those who are really really good.

Krogglidor
03-22-2010, 11:33 AM
I try to make my posts as gramaticaly correct as possible because of all of that "texting gibberish" that no one can read, I forgot to mention in my explination of my run that I do not use the portal edging routes because I don't like the idea of portal edging (if you are not in the portal then you should not be able to use it to get somewhere) and I just noticed that in you last post that you said the 4 second way of chamber 08, did you mean chamber 08 or 14 like I thought, if you meant chamber 08 are you talking about the way that you jump around the corner because that is not going to happen on the xbox and would still be realy hard on the computer.

nrnoble
03-22-2010, 06:39 PM
You're right, it was Chamber-14 not chamber-08. If you say you've actually done it in 4 second 1-2 times, then I'll beleive its possible. I can do it in about 10 seconds pretty consistantly. It has been a while since I tried the 4 second method, I'll try it again at a slow frame rate to see exacty what needs to happen to acheive 4 seconds. At the moment I am thinking it is a speed run that a person can do, but with a very low percentage of success. Maybe 1-2 times out of a hundred attempts.

Krogglidor
03-22-2010, 08:54 PM
I have managed to do it in 4 seconds twice in several thousand times I am on the xbox though so it is harder but it takes a long time for me to get it just once so I never even try that way anymore and take the 4 second hit.

nrnoble
03-24-2010, 12:38 AM
I'd think that doing Chamber-14 within 10 seconds would be impossible on Xbox\PS3...lol.

I have tweaked my time a bit on chamber-16. Got it down from 41 seconds to 35 seconds. Let me know what kind of times you can get using the route in my video. The route maybe technically shorter, but I am not certain that it can produce faster times than the route you have been using. I say that because technically your path is shorter in terms of steps that need to be taken. It is mostly shooting a lot of portals shots very very quickly. Mine takes less portals, but requires most steps which I believe and steps requires more time.

Chamber-16 speed run (http://www.youtube.com/watch?v=2LomF3S_LOk)

In the route I've tweaked, I think you'll easily be able to beat my 35 second time (right hand side of video). Even in the video I make a couple of mistakes that cost me at least 1-2 seconds. My overall problem is that I am past my prime in terms of eye\hand reaction time, about half as fast as I was in when I was at the top of my game (gaming in general). I still do OK, but all my videos are at a much slower pace than extremely fast speed runs. I need to take a slight pause often before shooting to make sure I'm on target, and that adds up to several extra seconds by the time I am finished with a speed run.

Krogglidor
03-24-2010, 09:09 PM
I could not get that bump to work, no matter how much I try, I do not think that, that bump works on the xbox either :(, but I would estimate that I would save 6 or 7 seconds which would bring my time on 16 down to 24 or 25 seconds, but that is just a guess because it does not seem to work. ;)

I am thinking about buying a recording device to record my xbox game, if so you should expect a video of my run in a week or two. ;)

nrnoble
03-24-2010, 09:23 PM
OK.... I'm going to fire up my 360 and see if I can get it work. I'm not sure I've even gotten as far as Chamber 16 on either the 360 or the PS3...LOL.

What recording devices can be bought? I take it some kind of box that records the video signal and makes it easy to transfer to a PC.

03-24-2010, 10:16 PM
http://hubpages.com/hub/Guides-to-Recording-Xbox-360-Gameplay-to-Desktop-or-Laptop this is what you can use for recording xbox, and if you do get it to work, tell me so I can try it out some more, I did not try for to long because I had to go to work.

nrnoble
03-24-2010, 11:54 PM
I am not having any success either on the 360. If it is doable, it is going to require a different sequence of events\moves\angles than the PC. On the PC, it is very straight forward\easy. Just run over into the corner and be pressing up against both walls, look straight up into the middle of the first square directly above, shoot Orange portal, without adjusting\changing aim then shot blue portal. Sometimes slight aiming adjustments need to be done before shooting the blue portal, but 90% of the time the both Orange\Blue portals can be shot to exactly the same spot.


It is very likely not doable simply because of the subtle technical differences between PC version and the 360, and could as simple as the screen resolution makes the difference, but who really knows. I did hook up the gamepad controller to my PC and was able to get to get it to work fine, so it is not likely related to the gamepad somehow.

One odd\interesting difference between the PC and 360 version is that the on the 360 the cross-hair has the portal color indicators reversed. On the PC, Blue is on upper left, on the 360, Orange is on the upper left, with blue at the lower right. A bit confusing\frustrating and throws off my timing significantly because I shoot portals in a very specific pattern without thinking. If this was a design decision, and I'm guessing it was, one logical reason behind reversing them would be to make it visually different from the PC, thus very difficult to make PC videos (ie speed runs)then claim it is a 360 video.

I am going to keep trying to see if I can get it to work.

Krogglidor
03-25-2010, 07:19 AM
The colours are reversed because on the xbox the default "shoot" button is the right trigger while on the computer it is the left click therefore reversing the colours because the blue goes to that default button.

nrnoble
03-26-2010, 12:33 AM
I did see that I can reverse the colors through the "controller" menu on the 360, so that fixes my problem. Doesn't help all that much, I am still pretty bad...lol.

Checked on the PS3 and I can't get the game portal bump either in that one location in the second room. Might be because it is in the ceiling.

Look forward to seeing some of your speedrun videos when you get it captured. The 360 really should have screen capture functionality built-into it.

Do you know if there anyway to activate the dev console on the 360?

Krogglidor
03-26-2010, 06:39 PM
there is no way to activate the dev console on a console, you can only activate it on the computer.

Krogglidor, on the xbox what is considered to be the start and end points for speed runs?

Krogglidor
03-29-2010, 06:00 AM
I just take the time from the last check point which is when you are flying into oblivion, as the end so the start is when you start the first chamber as you get out of the tube.

nrnoble
03-29-2010, 06:41 AM
Looks like my start to finish speedrun is currently just under 28 minutes. Not too bad for me

What is your best time for Chamber 19? Any good chamber-19 speedruns on youtube worth watching; runs that have actual game audio? The ones without game audio are highly suspect because they can be recorded at very slow frame rates, then speeded back up to look real.

There are several chambers I know I can trimmed down by several seconds. Chamber 19 I might be able to be dropped it by 1 minute if I do a few things differently\faster. But if I really wanted to get a significantly better end-to-end time, I'd think I would have to do some chamber runs using shortcuts that have a very low percentage of success. Type of tricks that work 1-2 times out every 100 attempts because there is no room for error and the timing required in down to just a few ms.

Krogglidor
03-29-2010, 08:38 AM
I do chamber 19 in, I think 4 minutes, I have ordered a capture card to record my runs on xbox, I expect it to arrive on Thursday or Friday so hopefully I can have the video up by Saturday or my run so you can see how I do it.

nrnoble
03-29-2010, 08:47 AM
WOW! 4 minutes. I'm doing Chamber 19 in about 10 minutes, which I know is a bit slow. In my last post I was curious\asking if anybody on youtube had posted speed runs that are impressive. Based on what you have posted previously, I understand that you have not made any videos because of the lack of capture hardware.

Krogglidor
03-29-2010, 08:53 AM
Edit: I just read your post all the way through and realized what you were saying, my computer is not working right now so I cannot post a link to a YouTube video but I can tell you the one I was going to post, it has sound but it still looks a little fishy to me but It was "runescapepking" that posted it and I found it when searching "portal chamber 19 speedrun" I hope that is enough info for you to find it.

Here is what I have for my final battle run. This 2 minute video covers the preceeding turret chamber.

Final GLaDOS Battle speedrun (http://www.youtube.com/watch?v=643spidgkd0)

It should reduce my chamber-19 run about 3 minute. When battling GLaDOS I had been doing it the typical slow way that takes 3-5 minutes. For this run I have not watched more than couple GLaDOS battles on youtube, so I don't know how it compares to other speed runs. I try to solve these things first before looking at how others have solved it. However, I did adopt the killing GLaDOS with a turret from a youtube video I saw, but the rest I came up pretty much on my own.

Here is my complete Chamber-19 run. It is was recorded in real time and the video is unedited: Chamber-19 run (http://www.youtube.com/watch?v=hnnItt5FdiU)

There are plenty of mistakes made throughout, but overall it is a decent timed run. The last two minutes is close to being mistake free. When putting this run together, I recorded over 50 previous attempts, but aborted them because I got jammed up somewhere and lost a lot of time.

That is a creative way to get back into the "impossible chamber" 06 I think, I am not sure though, i have never seen anyone do that portal bump before, I did not even know that you could bump portals like that. :/

Are you referring to the sequence between 00:44 - 00:45? If so, that is where 'noclip' comes in handy for analyzing maps for bump locations. :)

I keep waffling on whether or not portal bumping is something Valve intentionally left in the game. Not likely it was actually designed, but more like "wow that is kind of cool" glitch found during development, thus they decided to leave it in the game (saves money too, not having to fix it). If known in advance the design team might have made some map changes to allow for patterns to take advantage of it at specific points in the game, at least it appears that way. I could be over speculating, because some random things\events\glitches do turn out to well without actually having been designed that way.

I almost didn't post this run because of number of mistakes made. There are spots in the video that are hard for me to watch. The first 30 seconds is so slow, but every time I try to speed that part up, I over shoot somewhere and it ends up costing more time. Since I'd recorded that run, I've slowly walked through the entire chamber and discovered a few more angles that I not seen before that will make for a better speed run.

Krogglidor
04-06-2010, 10:34 PM
No, I was talking about the one at 1:00 it was not an edge glitch because of the fact that you were not at the edge of the portal (making it think you are half way through) so I assume it is a bump but I never knew that you could bump from wall to roof (givin the right angle and cercomstances) that was new to me. I bet with practice you can get the run down to atleast 6:00. They probably did realize that you can portal bump but found no way to fix it and adding black would make the look of it worse, or something like that.

That portal bump I saw in a youtube video at some time. I am not that obsessive to spend 100s of hours finding obscure cracks like that one. Those who are that obsessed have a future in game testing that I highly recommend that they pursue (seriously). :)

If I edited the video, I might get 15-20 seconds shaved off from the 'load' pauses. If I had a perfect run with this route I likely could gain maybe another 20-30 seconds. I no longer have the instant reflects I did many years ago, so even on a good day I am operating at 75% of what I could have done at my peek. :)

I've not spent much time experimenting with the various dev console commands that speed or slow things up\down. A few days ago I was watching some speed runs on youtube that were blazingly fast at speeds far faster than I could even come close to. Upon closer scrutiny, I noticed some\many of the videos appeared as if they were 'overclocked'; everything happened at a much faster pace, such as walking, falling, hopping, and shooting portals, but the sound was normal. Well, after some digging around I found out how some of the super duper incredible videos were faked using commands that require sv_cheats.

Here is a 60 second video I created that demonstrates one of the cheats frequently used to create faked speed runs on youtube:

Chamber-19: Speed run recorded at 120% normal speed (http://www.youtube.com/watch?v=wgmQpFzDuGI)

I find that if the speed is not jacked up more than 125% (normal speed + 25%), it is hard for the eye to detect the increase in speed over normal. At 25% that reduces the time about 10 seconds per minute in a speed run.

Here's a guy who has come clean.

Faked video: Chamber-15 in 28 seconds (http://www.youtube.com/watch?v=cR1P8Tm1fD8&feature=related)

This is the type of fake video that I believe caused Valve break demo playback completely (or caused them not to fix it). It ruins the Portal's overall credibility when anyone with just basic skills can create fake videos strictly using built-in dev commands.

Don't know what online store you bought it from. Through trial and error, I have discovered it is best to go with stores that have a well known track record (ie Amazon or ebay stores). If they don't have it in stock, they will list it as being on back order. Many shady stores will list 1000s of items, and not have a single item in stock. Once they get an order, then they go get it from the distributor. And I do recommend ebay sellers with high ratings.

It will be cool to see what you can do once you get it.

My end-to-end (00-19) speed run is down to 24-25 minutes from 28 minutes mainly by improving Chamber 19, which was 10 minutes and now is 7:22. I'm pretty sure I can get Chamber-19 under 7 minutes with a really good run. I've discovered a few more places where I can shave off a few seconds through a more direct path. Doing a slow walk through I saw angles I missed because I never fully studied certain parts of the chamber.

I am going to see how much I can improve on my Chamber-15 speed run. I like that chamber, it is well designed. Once I get a decent video, I'll post it.

It is a different way than I do, I throw the cube, because atleast for that one button the cube kind of gravitates (I don't know if I spelled that right :/ ) towards the button, because if you try it is much easier to throw the cube to that button than most other buttons in the game, like the one with 2 cubes and only blue portals, is realy hard. I have managed to get my time down to 12 and can probably get it to 11 with practice. What did the guy say that you removed the comment, I kind of want to know. :D

For 15 for the second fizzler jump you can portal the wall in the hallway across from the fizzler walk halfway through and shoot a portal at the ground in front of the fizzler and jump and shoot a portal at the ground in front of you to fly over the fence instead of doing it the actual way. ;)

I will try throwing the cube and see if I can improve my time. I have done it that way in the past, but have not spent any time practicing.

I didn't remove his comments, he removed it himself. I did get an youtube auto-generated email and the deleted message was simply 'awesome'. In a followup post he said he can do it in 9 seconds. If he can do it in 9 seconds real time and no cheats, he has to be leveraging some kind of OoB glitch. On a good real time run it takes 6 seconds just to get into the main chambered, so that leaves only three seconds to get into the elevator, which is not enough time.

I can do perfect test runs when I slow down the game to 50%-75%. Later, using Adobe Premiere, I speed up the recording to normal speed to estimate the total time it would be if I managed to have a legitimate real time perfect run. Using this method of testing, as far as I've been able to determine, it would not be possible to do a 9 second perfect run in real time.

On chamber 15, at 17 seconds you can turn to the right and put a portal up there then at the ground of the fizzler and right below you. Also you can at the last area, put a portal on the floor and ceiling, then as you are falling you can out another on the floor.

Throwing the cube still does save some time because of the fact that the wall is to your left there it saves a second or so. ;)

Need to practice it a bit and then include it into the overall speedrun. It's more tricky thus a higher risk that I mess up when I get to that section of the speedrun. This short clip took at least 20 recorded attempts before I got one I was happy with.

Recorded in real time using Fraps with a timer overlay applied using Adobe Premiere.

I'm at 18 seconds (for the time challenge though, not within the full run of the game); and it didn't even take all that much practice. Hadn't done a timed run of it for awhile since I did the least-portals and least-steps first and it still only took a few tries to get to 18. So a run even as low as 15 seconds should definitely be feasible if you put more time into this type of thing than I do.


Last time I timed myself through the whole game I was at about 35 minutes. That was for the moment the radio music started in the relaxation vault up til the moment GLaDOS starts dying and the crosshair disappears. No portal-bumping or OoB or any of that crap, just abused re-using ball launcher #1 in 17 and of course the portal-through-portal thing to skip the slow platforms. Could definitely do it quicker though as I ended up dying somewhere once and also got killed at the spot in the escape where you gotta let one of the two crushers pop you through a portal on the ceiling (sometimes you'll get an extra boost there and land in front of the next crushers instead of on top of them). Plus I took extra time at the end of Chamber18 because either my portal to the second platform missed or I landed next to the one on the first platform instead of in it.


Any tips for Chamber 16? I can barely get the silver time and can't figure any way to optimize my route...it might just be a practice thing for that one.

The way I managed to get gold on 16 my first time was to take the first cube with me and use that to kill the turrets in most of the rooms after that, my time that I have gotten for a full (segmented) run has been 18 minutes and 8 seconds from the beginning to the final auto-save for a the single segment that I did recently I got 21 minutes and 18 seconds both of these are with portal bumping though, saving me about 60 seconds in all (I agree with OoB being dumb) I actually have the fastest time in the world for a non-OoB run on a console. ;)

cwsault, for chamber-13 I have since gotten my time down to 16 seconds (Chamber-13 speed run (http://www.youtube.com/watch?v=PKQzZbyR8Xk)), so 19 seconds now does seem a tad slow, and I likely could squeak out 14-15 if I had the perfect run.

I agree that OoB as being invalid play because it takes the player outside of the game\map. All games have boundaries lines, and Oob play is like a player in any type of game (ie sports) where they go beyond the boundaries of valid play. Portal bumping is a grey area, and I lean toward it being OK since the player stays inside the map.

Thanks.... Yeah that one is fake. 110% fake as are all of his videos. There is a hack that replaces the regular 'Cheated' image during timed runs with the normal non-cheated image. Then of course he can use several other cheats all he wants.

What percentage rate are you able to do the hallway one without using the fling as I did in my last video? Even when I slow the game down to 25% I am not able to get that stunt to work. I don't have enough momentum to get over the fizzler barrier. I'm not even getting remotely close. I am wondering how easy it is to duplicated. For me it needs to be roughly 50% or better at normal speed otherwise I spend hours trying to do speed runs that fail with low percentage maneuvers. :)

04-19-2010, 07:32 AM
I get that move like 95% of the time, just stand in the portal and aim as close to the fizzler as you can then jump up and out and as you are flying upwards you need to know what direction to move in and you should get over almost every time.

Chamber-15: The very long jump (http://www.youtube.com/watch?v=OmnAA-6HOyg)

This really is an advanced maneuver because it takes understanding of how you enter a portal dramatically effects the trajectory of how you exit. Seems logical of course, but applying the nuances takes a lot of skill\practice.

Well now I hit 52:) Ended up doing it slightly differently -- rather than fiddle with the aiming in that tiny slit at the start I just dumped the first turret through a portal and jumped/ran around the corner, which turned out to be quicker for me at least since the aiming in that spot was sucking up time.

The camera drop at the end is prolly what makes the difference because it made the flow of taking out the three turrets in the button room go much better. Previously, I'd been dumping the one with its back to door onto the second one, then popping through the wall above the third and chucking it somewhere while heading for the button.

nrnoble
04-20-2010, 04:35 PM
The bottom line is to do it a way that works for you. There are even faster to ways to do Chamber-16, but they also have higher risk for failure unless you got a lot better timing that I do. I am decent, but my reflexes are slower than they were when I was in my gaming prime (15 - 30).... :)

I use the turret #1 to take out the Turret #2 because the cubes are placed in such a way they jam a high percentage of the time before you can unjam them, wasting at least 2-3 seconds. In my speed run, you notice that I place the Turret halfway through the open portal, thus it falls through when I shoot Portal #2 into the ceiling above Turret #2. This works well after a bit of practice. There are several different ways to handle the room with the three turrets; the way I do it is not the fastest, but it is highly repeatable 95% of the time. This overall elevator-to-elevator route is very easy and highly repeatable by anyone with basic Portal skills; how fast it is done is a matter of skill\practice.

Edit: Have you completed the other gold acheivenents for least time?

04-20-2010, 09:39 PM
Aye I noticed the cube jamming thing before; didn't think to use another turret til I saw your video. Even when they don't really jam they still take longer to get through than a turret. Oh and it's turret 2 taking out 3, #1 is the guy at the start with its back to ya who has a tendency to fall over at the slightest brush.:)

I think the number of Rep points given is a very small percent of to how many rep points I have; I don't know what is the top secret algorithm is that determine how much is handed out. :)

I might have spoke to soon about the very long jump in Chamber-15. At the moment I am get less than 5% success. Even when I slow the game way down to 25% where I can control the jump every time, when I exit the portal next to the fizzler, I'm headed directly straight up rather than over the barrier through the fizzler.

Here is what it looks like 95% of the time: Chamber-15: Long jump Test (http://www.youtube.com/watch?v=3xqSgSBFzgE)

At this point I've thinking two things. 1) There is something I'm just not understanding about the jump, and when it does work, it's more luck than skill. Or 2) There is some differences between the PC and 360, and this specific maneuver is much easier than on the 360.

It automaticaly trys to centre you in portals on the ground so if you enter the middle of the portal you are going to go up you need to enter the bottom of the portal so you continue to go forward. If you are in the centre it trys to keep you there so you are not going forward any more. ;)

Thanks. That is what I was thinking too.

I finally figured it out. I've been placing the 1st portal (in the floor) to close to the fizzler barrier, so even when I did jump through the second Portal correctly, I was hitting the top edge of the barrier. To avoid hitting the barrier, the first Portal either needs to be in the middle of the floor or further away from the barrier. I discovered this by slowing the game way way way down, giving me enough time to spin around in mid air and see that I kept smacking the edge quite a bit of the time (ouch!!). This was a problem because I kept loading the same saved game where the portal was already in the wrong place in the floor, so that the 100+ practice attempts I had done all had less than 5% of being successful.

Edit: And... it is critical that the gun be yanked up so it is headed in an upward direction before entering the portal. Ideally the gun is pointed straight up. If the gun is downward facing as you enter the portal, then the maneuver fails because it sends you up toward the ceiling rather than over the barrier.

This truly is the most difficult\advanced maneuver I have seen\done in Portal. Very very cool!

nrnoble
04-23-2010, 04:39 AM
There is a reasonable chance you will get your wish for the 360 because XBL already supports that kind of tracking if Valve decides they want to support leader boards. I think it is a great idea, and would love to have it for the PC version too, but think its doubtful at the moment because there is no existing infrastructure yet in Steam (Achievements yes, Leader board no). I would imagine that having leader boards means they would need take anti-cheat checking to another level because you know damn well game hackers will spend 1000s of hours trying to break any anti-cheat system that is in place. Nothing would be worse than have the top 100 on the leader boards be nothing by cheaters who's goal is take the fun and challenge away from legitimate players wanting to complete against each other.

Also, it is best, to encode youtube videos to H.264 because the files are small and youtube doesn't reprocess them quite as much. If not H.264, mpeg2 files is the second best choice, but the files are larger and take longer to upload.

This is how I compare chamber speedruns that are too close to call. What is interesting about this comparison is that two speed runs were recorded a few days apart, but they are nearly identical. The one on the right is about 5 frames faster (each frame is 1/60th of a second).

Just a couple tidbits I've found; dunno if they're relevant to your routes or not or if you're already using them--

--Chamber 11, after getting the orange portal and hitting the switch to open the door to the elevator room, I find the best spot to put the portal is on the ceiling. Seems to make it so the one you place by the acid pulls you in quicker once you're partially inside. Also aim as far to the back and right as you can, as that's right above the hallway to the emancipation grid

--Chamber 18, in the turret room, when you have your portal on the tilted wall you enter through, if you stand behind the tilted section (i.e. right where you were when coming into the room) and jump, you'll enter the portal even though its on the other side. So you can put the other portal on the wall above the floor platform and hop through rather than running the several paces over and jumping through.

Thanks, I shall consider your suggestions.

Currently I exit chamber-11 using either of these two methods:


Chamber-11 exit sequence #1 (http://www.youtube.com/watch?v=J6ANjhKJ4Cg)
Chamber-11 exit sequence #2 (http://www.youtube.com/watch?v=Ur6g_HoXKok)What I'm looking for right now how to do this one:

Ooh I've never even seen the actual exist hallway in 11 from the platform....must try that.

The cube throw annoys me to no end. I prolly chucked it a few dozen times with savepoints at various spots both before and after picking it up and it was still wildly inconsistent. It seemed to generally do better when aiming really high and jumping though; otherwise it just bounces off the front like in your video.

I think the best result I had was one fluke where it landed on the button and I fell into the gap -- if it was planned I prolly could've kept going straight down into the portal on the floor while the cube headed for the button....it's definitely doable to get the cube there but seems way more reproducible to not bother.

Managed to successfully hit the button with the cube. Took at least 25 attempts before I hit it. Not nearly as easy as throwing the cube in Chamber-13. Speculating, I've begun to wonder if the the original dev mappers tweaked the physics parameters for individual maps to some times make things easier\harder depending on the map\chamber. Clearly there is major difference between Chamber-12 and Chamber-13 in terms of throwing the cube to hit the button.

So far hitting that button appears to be practically impossible. I can do it about 1 in 25 attempts. I can hit the button about 25% of the time, but it bounces off like it is a rubber ball. Basically the throw has to be perfect or else the cube will bounce off the button.

Here is my segmented speedrun. Total time of 20:43. Recorded "live" using fraps. Just me, the keyboard, and the mouse... :)

It is not nearly as fast as other legitimate speedruns, but it is real. No scripts or game engine tweaks to enhance speedrun. And strictly within the boundaries of the map, no out of bounds play.
Part one: Chambers 00 - 10 (http://www.youtube.com/watch?v=po307IfqWPM)
Part two: Chambers 11 - 18 (http://www.youtube.com/watch?v=yk4-O1FrXJ0)
Part three: Chamber 19 - End (http://www.youtube.com/watch?v=9CCXYztgWUA)
About 85% is going to be very similar to other speedruns because there is very little new to be discovered after 3 years. However, here are a few segments of the speedrun that I like because I had not seen them before or I do them slightly different.
Chamber-05 (http://www.youtube.com/watch?v=po307IfqWPM#t=3m17s): This is the one of the quickest solutions I came up on my own.

Chamber-07 (http://www.youtube.com/watch?v=po307IfqWPM#t=4m30s): This solution is one of my favorites and one I had not seen on youtube. With a bit of practice, it is not too difficult to master.

Chamber-19: Last two minutes of speedrun (http://www.youtube.com/watch?v=9CCXYztgWUA#t=4m30s): How I deal with the Turret chamber is my own unique solution and it is extremely easy to replicate. The final battle is also unique, and I beleive it is the most efficient path to destroy GLaDOS; I take out GLaDOS under 40 seconds after entering the final chamber.

Nice run, you are probably #1 in your age group, hell you are probably in the top 1% out of everyone. ;)

LOL.... Thanks.

I am in the senior devision of over the age of 30. Sadly for everyone, in video gaming, most hit their peak in their mid 20s. After that there is a slow decline in reflexes. Thankfully muscle memory remains pretty good; I can play classic games with about 85% of the skill I did when I was 15.

As far as my speedrun, I figure I have room for about 30 seconds of improvements between 15-19, maybe 45 seconds if I really make some good improvements. Take Chamber-12 as example, I can shave 10-15 seconds if I could throw the cube so that it lands on button, but so far the best I can do is 1 out 50 attempts.

I have a question about speedruns: at what point is the game considered 'over'?

Is it when you are above ground? When the credit sequence thing starts (when the camera goes through the pipes and vents to the cake room)? When the credits are over?

For PC, it's done from when the timer starts in the first room until the last orb gets fizzled. Not sure about you xbox guys though :/.

Oh btw nr, my non-scripted run was 17:50 done around 1.5 years ago. No scripts, none of this player enhancement bs you accused me of with my latest run (still not sure why you think so, oh and I can live broadcast if you have xfire).

Good attempt though.

When the crosshair disappears. At the exact same time you will hear GLaDOS explode.

I always just timed it by the final auto save, which is when GLaDOS gets fully destroyed, right before your screen goes white. ;)

I think that is several seconds longer than what normally people end their time on the PC. I'll fire up the 360 and check.

Over at that SDA forum their is a big argument going on about Portal speedrun rules. Kind of fun to watch\read.

Here is my Chamber-04 speedrun (12 seconds) (http://www.youtube.com/watch?v=e8eDnjXeY6A) and the alternate version Chamber-04 speedrun (12 sec) v2 (http://www.youtube.com/watch?v=8dkc-I0jZzU)

The technique used here is to shoot the floor as the cube is falling. The momentum of the falling cube will reach the button. This one take a bit of skill\practice, and a bit of luck.

Something slightly easier to do consistantly with just a small amount of practice: Chamber-04 typical run (15 seconds) (http://www.youtube.com/watch?v=4n7cHRJ_YPc)
