Get Maximum Fps On Windows 7 & Graphic Options for Best Gameplay.

First step you are going to do is:


Go to start menu, RUN and open regedit. (Registry)
Then Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Audiosrv
Then click on DependOnService and delete the line "MMCSS"
Save changes...
Now go to RUN again and type in services.msc
There you find a service named Multimedia Class Scheduler, in Startup Type from Automatic we change it to Disabled so we will never have to deal with it again during startup.


After you've done the above steps that I wrote above once in game open the console and adjust the game settings like that : 

rate 25000
cl_cmdrate 101
cl_updaterate 101
cl_cmdbackup 2 
ex_interp 0.01
hud_fastswitch 1 (when you press e.g. 3 to get knife on your hands you dont need to press left click to to hold it)
net_graph 3
net_graphpos 1


Now Second Step is for Graphic Settings:

Here's few settings you should chang related to your video driver [3D settings] so you can have the best gameplay.


Anistropic filtering - The maximal possible.
Conformant texture clamp - OpenGL.
CPU acceleration - Single display performance.
Texture filtering Quality - High Performance.
Vertical Sync [vsync] - Off.


Third Step and the last thing is how to start your game from your video card's DLL for the highest FPS possible.

All you need to do is go to C:\Windows\system32\ and find the file

nvoglnt.dll - If you are using nVidia video card.
atioglxx.dll - If you are using ATI video card.
openGL.dll - If you are using another video card and not the ones specified above.

Next you copy this file and paste it in the GLDRV folder located in your Counter Strike directory.
Once you have copied it there open the txt file located in the GLDRV folder and write there

for nVidia :

Default Default
gldrv/nvoglnt.dll

for ATI :

Default Default
gldrv/atioglxx.dll

for anything else :

Default Default
gldrv/opengl32.dll

Save the txt document start CS and feel the change :)
