Hi, I have noticed on all nvidia drivers I have tried 17x.xx to 19x.xx when I play for long periods of time my performance slowly degrades. For example. I start crysis on high at 1280x1024 with 45-60fps. Once I reach the 3rd to 4th level im getting single digit frames. None of my components are overclocked. Does anyone have an idea of what might cause this. Also its not just crysis its every game. I run windows 7 X64. And my specs should be listed under my name.
