So after trying to tweak every possible setting in the game and the Nvidea Control Panel, i think i've found the solution for the constant stuttering people have with only 2gigs of vram. In the Nvidea control panel there's a setting called "virtual reality pre-rendered frames", by default it's set to 1 so i changed it to 2 and voila! All stuttering is gone now!! i'm running a gtx 680 2gb with i7 3770K oc'd to 4.2ghz and 8gb ram btw at high settings with fxaa, fps around 40 sometimes dropping to around 35.
