If I run Crysis 2 in DX11 mode, I get constant stuttering issues when I run around, or move the camera with my mouse. The issue is not present when I set the game in DX9 mode. The issue still occurs, even if I use DX11 but set all graphics options to Extreme. My fps is 100+ average. Vsync does not clear up the stuttering. It makes it worse. It is not a CF issue, because the issue still happens when I test each card on it's own. I've tried replacing drivers to 12.7 and 12.6, from 12.8 and the issue is still present. Please help.
