Tried installing these 3x with clean installs, but still having issues. RE5 in Dx10 was a complete slide show, but DX9 worked fine. AvP D3D11 Benchmark would stutter right after the loading screen ended, but the bench mark ran fine and was down a few FPS compare to 301.42. Had some strange artifacts in BF3 menu, and some flickering in game. Also, ConvertXtoDVD would stall or run errors. Went back to 301.42, all issues mentioned disappeared. BTW why is this a sticky?
