Hi,

so i have a dual 2687w cpu's with a gtx 690 with latest driver installed.

when i try a game like crysis 3 or metro last light on ultra/high and even medium (1920x1080) i get crazy frame drops to 1fps and 15fps in metro. and it bugs like hell i cant play normally even the intro in the menu of the games is buggy.. when i play less demanding game like crysis 2 its playable but shows less fps then other gtx 690 whould 40 fps less.

what could cause this? 

both cpu and gpu in sli are enabled.
