I have been having one hell of a time playing games on my XFX GeForce 9600 GSO with 768mb.
Only when playing a game, the game freezes, then comes backs. After that, the game will run perfectly fine as long as I don't move the mouse. The second I do move the mouse it freezes for a second or two again...
I have tried a lot of the latest drivers and each one results the same. I am downloading the leaked 190 right now.
