I own a pc with 2 Nvidia Geforce GTX 680's in SLI + 32gb ram + i7 3770k processor. All games used to play perfectly smoothly, until today. Battlefield 3 FPS started to drop to 40-50 FPS, when it used to play in 140FPS. Farcry 3 , Sniper elite, and all other games also started to play really slow too. I already updated all drivers, defragged the HD, but the issue wasnt solved. Any ideas or suggestions?
