Casey's Source Config & Tweak Guide

Last Updated: 12/18/05

Below is my expanded tweak guide for getting the best performance out of CS: Source.

Drivers

First and foremost, drivers are key to performance; but not all drivers are created equal, and no one driver is right for every card. It is up to you to research and test to find the best driver for your specific card. However, below are some generally recommended 3rd-party drivers for your brand of card. One thing to keep in mind: Just because a driver is newer doesn't mean it's better. You'll need to test different versions to find out which one best suits your card.

ATi Recommended Drivers:

OmegaDrivers
DNA-Drivers

nVidia Recommended Drivers:

DNA-Drivers
NGO Drivers

When removing previous driver installations, it's very important to make sure all files and registry entries have been removed before installing your new driver. Following these directions should help ensure your old drivers are properly uninstalled and new ones installed:

Download, install, and update Driver Cleaner
Download new driver
Uninstall previous driver via Add/Remove Programs in the Control Panel
Reboot in Safe Mode (F8)
Run Driver Cleaner
Reboot
Install new driver

Note: If you have discovered an optimal driver for a specific model of card, feel free to PM me and I'll compile a list of recommended drivers for different card models.

Launch Options

Source has many performance-friendly launch options built-in that you may find give you a significant performance gain.

Launch properties can be added by right-clicking Counter-Strike: Source in Steam's My Games menu, clicking Properties, then Launch Options.

-dxlevel: Sets the DirectX level Source runs in.

You may find that setting this value lower than what your card can actually support to yield a performance increase. For example, a DirectX 9 card may run significantly faster in DirectX 8. Below is the recommended usage:

-dxlevel 90 for DirectX 9
-dxlevel 81 for DirectX 8.1
-dxlevel 80 for DirectX 8
-dxlevel 70 for DirectX 7

-heapsize: Dedicates a specific amount of memory to Source.

Increasing the allotted memory can yield substantial performance gains. However, it is important that you dedicate the right amount of memory. Dedicating too much or too little could actually cause a performance decrease.

It is recommended you dedicate half of your system memory. Below is the recommended usage:

512MB System Memory: -heapsize 262144
1GB System Memory: -heapsize 524288
2GB System Memory: -heapsize 1048576

(I'll add more later.)

CVARs

The following is a list of CVAR tweaks I've compiled through experimenting and various research. These commands help to strike an appropriate balance between quality and performance. You can find other CFGs that basically destroy the look of the game. I tried to maintain the appeal of Source while making it playable. These commands are CAL / CSP compliant.

Simply paste the following into Notepad, and save the file as autoexec.cfg in your Steam\SteamApps\your@email.com\counter-strike source\cstrike\cfg folder.

Note: The comments will not interfere with the commands.

Casey's config actually has some illegal commands in it so I wouldn't suggest freely using it in cal matches.

my pc
Css Cal Config Client

Replying to x2crazy4shadyx


I have a nvidia 8600 gt XXX pentium 4 3.2 processor and 2 gigs of ram.

I CANT run counterstrike cz or 1.6 at 100 fps constant its really annoying and they are really old games. And I play a little cs:s too and I get about 40 average fps, and did I mention also I'm running on vista. I need to know what are some good drivers for my video card and if you can give me some other stuff thanks.

Short of getting any tweaks or cfg's id say dump windows vista and settle for xp. Vista needs a lot of resources to run and is only worthwhile on a very good computer. With a pc of your specs vista is not worth it and is holding you back ;).

Well, you should try using Windows 2000, press windows key + Page break, then go to advanced, then go to settings click adjust for perfomance.

You should use cevos config for fps it's the best out here Click Here For Cevo Fps Cfg

Some cards run better with trillinear and not bilinear. try lowering down the Resolution to 800x600 or lower.

Also try using refresh lock or something to lock you're Hz

f*** that

Keep vista... If it runs to many resources you need a damn upgrade... It takes about 1GB of ram to run vista.. So 2GB is garbage. Get minimum 3. I got 4GB and run css on a laptop. It runs great. About 60fps

Hmmmm....
Css Cal Config Client

I only have 2 gig of ddr 500 @ ddr 540 and easily surpass 140fps at all times ingame.

I am also using vista 64 ultimate. 2 gig is more than sufficient for css on vista. Your opinion is garbage, and its uneducated to think that 2 gig is worthless.
