my rig is
Intel Core I7 5820K @ 4.3ghz
EVGA GTX 980 Classified
Corsair Vengeance LPX 16GB 4x(4GB) DDR4 @2666mhz
Windows 8.1 Pro 64-bit
have latest 347.52 nvidia driver installed.
game seems to run smooth then when moving around or sometime changing weapons. game framerate dips from 100 fps to like 10fps or even just just plain freezes for a good second. then continues. sometimes its so bad that game will just plain freeze for more than a second then crashes showing DXGI device hang error cryengine.
also noticed that even on high pre set (not very high) all 4GB’s of my VRAM is being used. not sure if this has anything to do with the stuttering. if i set game to medium quality. game still stutters but only uses 2.4GB of vram instead of all 4GB’s.
here is a picture of playing the game on high settings 1920x1080 gsync enabled with all 4 gb’s being used and huge frame drops happening.
