Below is my expanded tweak guide for getting the best performance out of CS: Source.
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 to than what your card can actually support yields a performance increase. For example, a DirectX 9 card may run significantly faster in DirectX 8.1. Again, it is best to test various settings to find out what is right for you. Use the following:
-dxlevel 95 for DirectX 9c
-dxlevel 90 for DirectX 9
-dxlevel 81 for DirectX 8.1
-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
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
