It will be working fine, smooth as silk in Chrome (does it in Internet Explorer, too)... and then just decide to start looking more like 30fps than 120. Have vsync and all that working fine, it works sometimes for 5 minutes or so, and then splat. The weird part is... the screen is still at 120Hz when it happens and ufotest is valid and stable and looks smooth going across the screen horizontal. But scrolling vertical looks horrible. Sometimes it will just randomly go back to looking smooth... too. No clue what's going on.

Is this with Windows 8.1? I haven't used Windows 8.1 much, but it seems to throttle the UI frame rate when GPU utilization is low, which can make scrolling and moving windows around choppy. That shouldn't affect games though. If it's not that, then I'm not sure what you're seeing.
