Thats so weird, I have a friend who has a similar system, just with the 770 gtx and seems to run at 60 FPS in town consistantly (ive seen it at his place) SO I have no idea what it is. I know he has an asus 87z pro MB, i5-4670k @ 4.7ghz, 8gb of 1866 ram and the 770gtx. So I just dont understand it.
