A few minutes after I launch a game (like Skyrim) the performance starts to drop quickly, even tho my fps drop is little (like ~4 frames). If I pause the game and unpause after a few seconds the lag goes away, but not for long.
I've already measured the GPU temperatures throuh HWMonitor, never went above 75ºC.
Also I'm running on the uptaded driver, 306.97. Using these settings. Tho it doesnt matter if I run on medium/low.
Another curious thing is how the lag is: every half second it "mini freeze" and like "compensates" with some kind of FastFoward.
My specs are:
- MB Asus M5A88V-EVO
- Phenom II X4 955
- 3x 2048mb Corsair 1600MHz
- GTX560 TI
- PSU Seventeam ST-850Z-AF
Things I've tried:
Formating the HD and installing it all back again.
Limiting the fps rate with nvidia inspector and setting the v-sync to force on (lag seems to disapear, but with a high amount of fps drop).
Setting the power management to "maximum performance".
