Re: Integrated Geforce 8200 woes: high X CPU on video playback
I have a hunch that this issue comes up when you play a video using a refresh rate that is a multiple of the video frame rate and have vsync enabled. I cannot play 24 fps material on my tv while having 24 Hz enabled without getting random, irritating video stuttering. I have a feeling that I once tried 72 Hz on my CRT to see what the video looked like (I normally use 85 Hz, which doesn't match any common framerate) and got the same problem. I can't confirm now, though, since twinview doesn't list that refresh rate with my current config for some reason.
The only difference UseEvents makes for me is that the cpu usage stays normal, video still twitches randomly.
