A Guide To Help Eliminate Stutter!

This thread's purpose is to address the widespread stutter issues people are facing. Below is a list of steps to take, in order to ensure that your PC is prepared for S.T.A.L.K.E.R. and that S.T.A.L.K.E.R. is prepared for your PC. As well as improving S.T.A.L.K.E.R. performance, this guide should improve the general overall responsiveness of your system, and in doing so, should also improve performance in other games, not just S.T.A.L.K.E.R. If you spot any fallacious statements, and/or you have suggestions for improving this guide, please do not hesitate to contact me.


-------------------

Step #1.) Update all of your drivers to the latest version. By "all" of your drivers, I really do mean all of them: motheboard/chipset driver, graphics driver, audio driver, any necessary perhipial driver(s), etc.


-------------------

Step #2.) If running the game with Full Dynamic Lighting, install the latest official version of the Float32 mod. This mod is a miracle-worker, and can be found here:

[link]http://www.thefloatingpoint.org/main/download.php?list.4[/link]


-------------------

Step #3.) Update S.T.A.L.K.E.R.'s core OpenAL files for improved performance. Click on the link below, and download and install the file.

[link]http://developer.creative.com/articles/article.asp?cat=1&sbcat=31&top=38&aid=46&file=oalinst.exe[/link]

Once done, navigate to your C:/WINDOWS/system32 directory, and copy the files entitled "OpenAL32.dll" and "wrap_oal.dll". Then, paste the files to your desktop, and navigate to your C:/Program Files/THQ/S.T.A.L.K.E.R. - Shadow of Chernobyl/bin directory. Here you should see two files with identical names to those you just pasted to your desktop. Move them to a folder you can find them in later if something goes wrong, and then proceed to paste "OpenAL32.dll" and "wrap_oal.dll" from your desktop to your C:/Program Files/THQ/S.T.A.L.K.E.R. - Shadow of Chernobyl/bin directory. Congratulations, you have just updated S.T.A.L.K.E.R.'s core audio files.


-------------------

Step #4.) Disable prefetching of game data. Go to your S.T.A.L.K.E.R. launch icon, right-click on it and select Properties. Then in the Target box, one space after the last character, insert the switch "-noprefetch" (without the quotes).


-------------------

Step #5.) Disable all unnecessary 'automatic updating' services. This includes disabling Windows Automatic Updates, and instead manually checking for updates at the beginning of each month in this address:

[link]http://update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us[/link]

There are also numerous other programs responsible for hogging your PC's memory and CPU cycles with their updating agents. To observe a list of programs which have scheduled updates active, navigate to C:/WINDOWS/Tasks.


-------------------

Step #6.) Disable all unnecessary startup programs. Download and install CCleaner from the following link:

[link]http://www.filehippo.com/download/751ed68330a1fa7712035248d9aebaab/download/[/link]

Then, start the program and go to the 'Tools' section. Click on the "Startup" button and remove any items in the list which you think are unnecessary. These items can include (for example) Adobe Speed Start, Adobe Synchronizer, iTunesHelper, etc. etc. If you're not sure whether something is safe to delete, use your best friend: Google.


-------------------

Step #7.) Disable all unnecessary services. This is an important one. Go Start --> Run... and type "services.msc" into the box (without the quotes) and hit OK. Then start disabling/setting to "manual" all services which are unnecessary to have running all the time. For proper guidance on how to do this safely, see the following links:

[link]http://www.blackviper.com/WinXP/servicecfg.htm[/link]
[link]http://www.theeldergeek.com/services_guide.htm[/link]


-------------------

Step #8.) Consult TweakGuides.com for information on how to set up S.T.A.L.K.E.R., your graphics display driver and operating system for maximum performance and stability.

[link]http://www.tweakguides.com/[/link]
[link]http://www.tweakguides.com/TGTC.html[/link]
[link]http://www.tweakguides.com/STALKER_1.html[/link]


-------------------

Step #9.) Defragment your hard-drive:

(A.) Go Start --> Run... and type "rundll32.exe, advapi32.dll, ProcessIdleTasks" (without the quotes) into the box and hit OK. Monitor your CPU/memory usage from Task Manager, and once it returns back to normal, move on the next part.

(B.) Go Start --> Run... and type "defrag [drive letter] -b" (without the quotes) into the box and hit OK. So for example, if you only have one hard-drive which has a name "c:", you would write "defrag c: -b" into the box. A Command Prompt window entitled "Defrag.exe" should pop up. Once it disappears, move on to the next part.

(C.) Go Start --> Programs --> Accessories --> System Tools --> Disk Defragmenter, or alternatively, use third-party defragmenting software, and defragment your hard-drive.


-------------------

Step #10.) Make sure you have a contiguous pagefile, at least 1536mb in size. Right-click on My Computer, and select Properties. Then click the 'Advanced' tab and choose 'Settings' under 'Performance'. In 'Performance Options' choose the 'Advanced' tab and under 'Virtual Memory', click 'Change'. Then, choose "No paging file", click Set, then OK, and reboot your PC. Once done, navigate to the aforementioned window again and select "Custom size". Write whatever value corresponds to your RAM amount (from the list below) in both boxes (entitled 'Initial size' and 'Maximum size' respectively). Now choose "Set", and then OK to accept the changes. So, for example, if you have 1024MB (= 1Gb) of RAM, you should write "2048" (without the quotes) into both boxes.

NOTE: The recommended pagefile sizes in accordance to the amount of RAM one is in possession of are given below. These recommendations are my personal opinion, but should be quite reliable and work for most people.

RAM ...................... PF Size

512MB .................. 2560MB
1024MB ................ 2048MB
1536MB ................ 1536MB
2048MB/more ....... 1024MB

As you can see, all of these corresponding values add up to a grand total of 3Gb of allocatable memory. Since S.T.A.L.K.E.R. alone can use a tad over 2Gb in some cases, and background applications may exceed 500MB of memory usage (though they shouldn't if you use consult this guide), I feel that 3Gb of allocatable memory is the perfect amount. You may disagree, in which case you can of course use a different value than given on the list above. Your choice.


-------------------

Step #11.) Quit all other non-essential programs before playing S.T.A.L.K.E.R. This includes programs like X-Fire, MSN, Firefox/Internet Explorer, any music player(s) you have open, etc.


-------------------

Other potentially useful tips for improving S.T.A.L.K.E.R. performance:

* If in possession of 1Gb or more of RAM, allocate more memory to sound caching for reduced stutter. Navigate to your C:/Documents and Settings/All Users/Documents/STALKER-SHOC directory and open the file named "user.ltx" with a text editor. Give the snd_cache_size -variable a value of "32" (without the quotes).

* Restart explorer.exe prior to launching S.T.A.L.K.E.R., in order to free up precious memory. Explorer.exe is commonly known as "Windows Explorer", and manages the Windows Graphical Shell. Upon termination of explorer.exe, Windows's graphical interface will disappear. In layman's terms, this means that when you close explorer.exe, nothing besides your desktop wallpaper & any open third-party program windows (such as Firefox) will be visible to you. Your taskbar will disappear, as will your icons.

The reason we want to restart explorer.exe is simple: to free up any excess memory that the process has bound to itself upon being active. To do this, Press the keys "CTRL", "ALT" and "DEL" simultaneously. This should bring up Task Manager. Find explorer.exe in the list of processes under the appropriately labeled "Processes" tab. Then, right-click on it, and select "End Process". When Windows prompts you about losing data, etc. just answer "Yes", as there is no danger of losing data here. Now, you should witness your taskbar and desktop icons disappear. Once that happens, bring up Task Manager again, and go File --> New Task. Write "explorer.exe" (without the quotes) into the 'Open:' box, and once done, click OK. You should now witness your taskbar and icons reappear. You have just restarted explorer.exe, and unbound any valuable memory that the process had previously kept occupied to itself for no good reason.

* When playing, use perma-bodies to stash items. After some investigation, I have discovered that most stashes residing in S.T.A.L.K.E.R.'s game world create lag over time, when overloaded with items. This lag can add up to about 15-40 second pauses, and can be almost entirely avoided by using "perma-bodies" (= permanent corpses lying around the game world) to stash items instead. These perma-bodies do not cause severe lag, unlike most regular stashes. An example of a perma-body would be the lone stalker near the truck visible to you upon entry to Rostok from the Garbage. This particular stalker is dressed in a white leather jacket.

* When playing, try to stash your items in an area where few major battles take place/ an area which you seldom visit. We already know that stashes create lag when loaded with items, and we also know that lag/stutter is worst during a battle, because that is when it can really disrupt gameplay. The Bar is a great place to stash items in, because unless you are an enemy with duty, the area is quite calm. If all of your items were stashed in the bar, and you ventured off to another area, you should theoretically be able to avoid any lag caused by stashes in that area.

* Lower in-game texture detail. Video memory on-board your graphics card is a limited supply; higher texture detail renders more video memory (Vram) used, which in turn can lead to stutter if the amount of space occupied by this texture data exceeds your Vram amount. In this case, the only means of remedying the issue is by either purchasing a new graphics card with a higher amount of Vram, or to lower in-game texture quality.

* If using Full Dynamic Lighting and none of the previous works, switch to the DX8 renderer (Static Lighting). Not only does Full Dynamic Lighting introduce some very nice dynamic lights and shadows, it also introduces a great deal of techniques which enhance the appearance of textures, like for example parallax mapping, etc. With these techniques enabled, S.T.A.L.K.E.R.'s textures take up a great deal more space than they do with Static Lighting. So, if all else fails, switch to Static Lighting. Note that Static Lighting remedying stuttering issues is more than likely an issue with insufficient system RAM / Vram, in which case it would be more prudent to lower texture quality instead of switching to Static Lighting, of course assuming that you have a card capable of handling Full Dynamic Lighting framerate-wise to begin with.

* Purchase more RAM. I know, I know; This is not something you want to hear, but S.T.A.L.K.E.R. is a serious memory-hog. The game is playable on 1Gb, but it really requires at least 2Gb for smooth and enjoyable gameplay. Note that this step is a non-essential one, but a strongly recommended one nevertheless.

omg you just gave me a pointer to check on

Nicely Worded. Tons of good key points everyone with problems should be looking into instead of throwing up there hands in the air thrashing about the game and I'm sure the developer is working on important they don't just happen on a snap of the finger. My first problem I encountered when I got the game was the sky was all jacked up and extremely laggy >.> only took a $70 dollar upgrade -.- everything is working....

[bold]
I'm going to try the corpse stashing after reading it hit me that the second delay pauses have occurred after obtaining a bunch of loot >.<; [/bold] thank u

Keep up the tips and tricks forums posting. where theres a will theres a way.

p.s. those who can't open the trader door take a body stand 90 degree and slam the corpse to it the door will open

Something I missed in the guide...

... Was updating DirectX. Basically, if you have a DirectX 9.0 capable graphics card, you ought to make sure your DirectX version is up to date. Go to the link below, download the file and extract its contents to a location you find convenient. Then, double-click on the executable entitled "Setup.exe" and follow the on-screen instructions to install what you just extracted.

If you close down Explorer, why not just start Stalker from the command-line in stead of restarting Explorer??? Stalker runs fine without the Windows Graphical Shell (on XP sp2) and that'll save even more precious memory.

OpenAL is a cross-platform 3D audio API appropriate for use with gaming applications and many other types of audio applications. It's S.T.A.L.K.E.R.'s core audio files. Updating them from the original version that comes with the game to the newest should improve performance (ref Decane who started this thread).

I'm glad the guide worked for you. If it really did have the influence you claim it had, it's likely that you were running quite a lot of unnecessary stuff you didn't need hogging up your resources. I highly doubt that a no-CD crack would do anything for performance though...

By the way, here is the new DirectX November link. The one posted a few posts above is no longer up-to-date.

This is the only solution for stutter, especially for 1.04 patch. With 1GB of RAM under Windows XP it takes me five minutes to load any level and next five minutes to load the rest of the level and stop stutter. My hard drive LED is continuously flashing all the time. I thought at first that CPU or video card are not up to the task but then I remembered playing Amiga games 15 years ago when similar wild non-stop floppy drive access happened. Doubling RAM then solved the problem so I decided to do the same thing. Adding 1GB of RAM to total of 2GB of RAM solved the problem. Levels load in less than a minute and stutter is gone for good.

My suggestion is that you people at GSC stop pretending that STALKER can run properly on 1GB of RAM and admit that 2GB of RAM is mandatory, at least for patch 1.04 that severely aggravated stuttering problem and increased loading times. For your next game STALKER: Clear Skies I suggest better optimization of textures because if you do not address this problem now not even 4GB of RAM under Vista will be enough to run the game smoothly.

Further notes on killing explorer.exe...

The process should be "killed" in a manner different to what I described in the main post. Here is a clean way of disabling the service:

1) Go to the Start menu and select “Shut Down”.

2) Hold down CTRL, ALT, and SHIFT, and then click the Cancel button on the window. YOU MUST BE HOLDING DOWN CTRL, ALT, SHIFT WHEN CLICKING THE BUTTON! This will cleanly terminate exploer.exe.

3) When you need to start S.T.A.L.K.E.R., you will do so from a shortcut. Just bring up Task Manager by pressing CTRL, ALT and DEL, and navigate to "File" --> "New Task (Run...)", then click "Browse..." and navigate to your S.T.A.L.K.E.R. shortcut. Then click OK and the game should run.

4) When you quit the game, bring up Task Manager again and write "explorer.exe" (without the quotes) into "New Task (Run...)", and click OK. That should do it.

Nice that someones taken the time to clue people up onto how to maintain their pc's but im confused on one part.

rundll32.exe advapi32.dll,ProcessIdleTasks

Usually you enter that into the command prompt when you want to fix your prefetch folder if youve damaged it due to deleting everything inside that folder (it will rebuild 2 files).

You should probably call it part 10 (after the defrag part) and teach people how to prefetch boot only, its definately not a command i would recommend using for a normal defrag.

Regarding rundll32.exe advapi32.dll,ProcessIdleTasks...

Idle Task Scheduling: The ProcessIdleTask API

The file placement optimization, which is done no more often than once every three days, is an example of a task that is carried out when the system is deemed to be idle. System Restore and other features of Windows XP also attempt to defer some work until the system is deemed to be idle. There are also some done-once-after-setup work items that also operate under the Idle Task Scheduling mechanisms.

All of these "idle tasks" are controllable by a system API in advapi32.dll, ProcessIdleTasks. The APIs sole purpose is to allow benchmarks a simple way to force any pending idle tasks to be executed immediately, without having to wait a lengthy period of time.

The API ProcessIdleTasks can be called in one of two ways, from the command line or synchronously from a program. To call ProcessIdleTasks from the command line, use this syntax:

Rundll32.exe advapi32.dll,ProcessIdleTasks

When called from the command line, the ProcessIdleTasks work is done in the background asynchronously. It can take 10 to 15 minutes for idle tasks to complete. Task Manager will report processes running, and the disk will likely be active during this time.


Source: http://www.microsoft.com/whdc/archive/benchmark.mspx#EFF

In short, the command will immediately execute idle tasks, and force an automated file placement optimization to occur spontaneously (rather than after each three-day interval), which *theoretically* should improve performance. This will also ensure that failure to deem the PC idle will not account for reduced performance when the user is for example playing S.T.A.L.K.E.R., since the disk optimization mechanism described above automatically takes place every three days. That is, the next time it will occur will be three days after you have executed it manually via the command prompt parameter above. Unless there's something I don't quite understand, that is...

"Float32 for Clear Sky" available from floatingpoint.org...

Is it ok to use for "Shadow of Chernobyl" too, or are they incompatible?
I'm hoping to improve a bit on the stutter-thing.

Won't work -- in CS, there's a folder entitled "R3" (abbreviation for "Renderer 3", or DX10 mode) inside the shaders\ folder, which is where Float32 0.5 for CS inserts a file. In SoC, no such folder exists, and hence, the game will not look for the file either.

i know this has been died for some time. but i now have been chasing this stuttering problem for some time now. and now it is at a all time high. and with this new gfx card i have there should be none at all.

the gtx285sc and i do know i have been trying out different gfx driver as well. since i do know that SoC is weird like that. but this driver i am on once again is great for all my games but now this.

i went and tried the openAL trick inwhich i lost all sound! i still do not under stand how or why that happens. good thing you keep the originals around to put back.

page file is set to 4096 since i do have 8gigs of ram. and i am in xp pro 32bit right now. since SoC is install on it. clear sky is on the vista ult 64bit

and all so all my driver and bios are up to date like normal. i am a hard core pc gamer BTW

even set snd_cache 32 as well, wonder if i could set it to 64 instead? since i do have a sound card.

but main reason why i am posting in this dead topic is why my sound is dead after doing the openAL trick when it shouldn't? that 1 is got me to be bad GSC couldn't do that in there patch so that way it will help us out so we are not trying to do it our self.

or messing something up when we should not have to either.

so can someone help me with this 3gb switch and xp 32bit sp3 since google is lost. since i have spent like 3 days searching and still have not found anything that comes even close to what is even in my boot ini file yet.

and since i do not want to take a chance and mess my xp system for some thing that should not have to be done by the customer. it should have done by the compnay they should have fix there game so a customer that paid there hard earn cash shouldnt have to.

so optimize the game for once and for all with 1 patch and forget all about the stupid multi player crap since that is what it is plain and simple.

there is no reason why a person has to take a chance and mess up there OS to make a game run better. there is no reason for it at all.

and no reason why a paying customer has to disable there system to play ! game at all either.

and if a moderator comes in and say this game is all ready been optimized i will go ballistic!! cause it is not even close to being so.

cause if it was optimized why would there be any stuttering or game pausing then? if it was? cause there wouldnt be thats why. and there wouldnt be no post in the bugs tech section either since that is what most of them are any way.

So I guess I'm having some pretty annoying stutters.

Running a quad Q660
4gigs of ram
ATI 4850 512mb

I usually can run the game at max with 60fps in most areas.

Didn't get much stuttering issues early on in the cordon area, just half second stops when you sprinted across the map. It's not until I reached the Army warehouses where it gets a little worse but more specifically the Red forest seems quite unplayable.

The game will freeze for up a minute before starting again yet sometimes the enemies have moved about or more have spawned. Thus it's made it very difficult to continue.

And I've tried No prefetch and it doesn't seem to affect it at all.

Is Clear sky any better?

Stutter/hangs in Vista 32 or 64?

This subject is mentioned elsewhere on these boards, but people looking for a stutter-fix might look in this thread for it. I discovered this fix when troubleshooting a troublesome mod, but has found it to have a positive effect in vanilla also.

( I posted this on another forum as well )

This mod ( Newsa+Simbeon 3.0 ) is the biggest mem-hog i have experienced yet. I never had frequent out of memory CTDs before playing NewSim on this (struggling?) laptop:
2.5 GHz Intelcore2 duo T9300, 4GB Ram 332.6 MHz ( 8.5 GB virtual memory ), Geforce 8600M GT 512MB, Vista Ult.64bit.

However, after some troubleshooting on this specific issue, i´ve discovered a possible solution, that just might kill your "out of memory" -errorserrors...and greatly reduce the hangshangs...

For Win Vista 32 & 64 bit.

If your system has more than 2GB of availiable ( virtual ) memory, you need to make the OS avare of this. It is wrongful to assume that the Vista 32 and 64 bit OS is not limited by the 2GB virtual mem-limit. It is most likely set at 2048MB per default, which is more than enough for most ( SP ) games released to this date, but Stalker SoC/CS are exceptions to this rule, as they´ll eat up 1.6 GB just to load the vanilla game.

As you are used to being warned, it is indeed a good idea to create a backup of things such as the BCDEdit.exe (Vistas boot.ini file) before making any changes to it. ( read: Make a backup before toying with stuff like this! Just do it! )

And remember that "DooMike" can and will NOT in any way be held reponsible for any damage YOU do to any PC!


To create a backup: (from within the bcdedit.exe)
bcdedit /export "c:\temp\myBCDbackup"
To restore a saved backup:
bcdedit /import "c:\temp\myBCDbackup”

The fix:

[link] http://www.nvnews.net/vbulletin/showthread.php?t=89138 [/link]

[link] http://msdn.microsoft.com/en-us/library/aa906211.aspx [/link]

"Start --> All Programs --> Accessories --> ( Right click on ) Run ( As Administrator ) It's important it says "This task will be created with administritive privileges"
Now enter: bcdedit /set IncreaseUserVA 3072 ( anything above 2600 and below 3072 will do )

Simply paste :- bcdedit /set IncreaseUserVA 3072 and click run ( hit enter ), you'll see a black screen pop up and disappear again quickly... reboot and you should be set... it's kinda like using the /3GB switch in XP.

After that you have to restart Vista. This is important!


This has not only (apparently) cured my out of mem-CTDs, but has also greatly reduced the well known in-game stuttering/hangs in general. I have played New+Sim for 5-6 real-time hours straight without a single crash, where there would´ve been at least a handful before, and am currently testing other "troublesome" mods with the same positive result.

Hope this will prove to be useful to other Stalkers ... Lost in Oblivion.

Sound related stutter

Nobody here have been able to tell me why or how this works, but i am experiencing less hangs/stutter after reducing the "snd_targets" value to 16 instead of the default 32 in the user.ltx file. "snd_cache" should probably be set at 32.

Maybe my onboard sound ( laptop ) was struggling to keep up, but it sure works for me!

i havent tried your other post since i am on vista ultimate 64bit. but this sound setting got me thinking.

so i check mine and it was set to 16 so i set mine to 32 since i have a sound card. but it didnt help with the stuttering though.

this is the only game i have out of 40+ that has the stuttering and i cant even get rid of it.

really sucks since this is 1 of my most favorite games to play.

I downloaded that explorer and looked at my EXE file, but it already had checked the >2GB memory. I run Vista64 and have the Steam client. I'm also using the Complete 2009 mod, and was noticing some pretty bad choppiness in Army Warehouses. I have 8GB RAM and a 512M graphics card. Previously I had been running in High graphics with full dynamic, but I cranked it down to Medium and that seems to have jacked up the framerate quite a bit in that area and still looks pretty decent.

I *always* get stutter in areas with a full stashbox. I had a bunch of junk in the box in the trailer at the northern exit from Garbage to the Bar and it caused ~5-10 second lags every time when I got near the flea market. I moved that stuff to the Bar, and it still lags by the flea market but not so much. Now it lags near the bridge into the Bar area where the dogs all run up and munch on you while you are lagged out and you are dead when it un-freezes. Heh.

So I shoot all the dogs every time and never make a run for it now. Surely somebody has a solution for the stash box lag problem?

Weird - the guy that posted after you has deleted his post. Anyway, use perma-corpses instead of stashes.

Hi ,

a word of caution , had one that exploded , ....

use a stash that has been found before , i always leave a single bandage in a stash so i know where they are with the minimap.

to speed up the system use a usb stick of 8 gig , that way you get at least 4 gig extra boost on the older systems.

what else can you do ?

click the properties of a disk under * computer * > hardware > select the drive and click * properties * > tab * policies *

select ' enable write caching on the disk ' you can also flag ' enabel advanced performance ' but this is only recommended if you have a powersupply (!!) this will speed up your system but back up all in case you ever have a powerfailure.

you can also tweak the reg a bit but email for that with soft and hardware details.

close all programs you dont need whileplaying like the internet , mail , messenger , etc , ....

play in full screen instead of a window helps also

just some tips that i used this week for some older comps under vista and 7 to play better.

have a nice day

Yes - each corpse actually has a weight limit defined in the ltx files. If you go past that weight limit, you will find that the items end up exploding everywhere. I've had that happen to me on two occasions, and I posted a thread each time with some lovely pictures and videos of the event. It is an awesome sight...but it will bring your PC to its knees.

One of the threads is here:
