It doesn't seem to be working for me, though I'm not certain. I know I hear no chime when it should load and the games still aren't seeming effected yet. My problem is on my HDTV with my GTX 670 when I move around it shows some tearing, I know many say this is due to drops in FPS but honestly it seems to happen no matter the FPS, it's just bad rendering. However in Windows 7 I use to have Triple Buffering forced on and this prevented that effect. Anyways does anyone know if it works in Windows 8?
