I just switched to windows 7 and now I have only 40-50 fps on some maps when I had constant 125 fps with winxp on all maps.
I installed the latest drivers and I'm using my ql config I used on windows xp.

Other than that I didnt do much, so I need some advice how to setup windows 7.

My System:
core2 duo 2 ghz
nvidia geforce 8800 gt
