Posted this in the 340.43 thread, but will duplicate it here since you're asking: "I have the same issue in 3D content with both 337.88 and 340.43 beta drivers. Any movement or scene change causes weird flickering/choppiness. It also makes eyes sore, similar to when you have your left/right-eye-first setting set up incorrectly, but this problem is not affected by that setting. Only downgrade to a driver earlier than 337.88 solves the problem. If you pause the movie where movement with that effect is present, it looks OK. Thus, it is only visible in motion. My setup: The PC is hooked up to a Panasonic VT50 HDTV via HDMI (also with DVI-HDMI adapter since GTX 690 does not have HDMI). The effect is present in any movie I tried, e.g. "Rio 2". The display resolution: 1920x1080.
