Re: Integrated Geforce 8200 woes: high X CPU on video playback
To get tear-free video in mythtv I need either the sync-to-vblank on in nvidia-settings or in mythtv (or both, I suppose), but then I get this Xorg CPU hogging issue. It appears after a while watching a recording or live TV - regardless of the broadcast resolution. Despite the CPU use I don't get any stuttering or lost frames. I'm quite happy with the smoothness of the playback, which is why I've chosen to ignore the problem and hope it goes away.
I haven't actually tried running without either sync-to-vblank option (and trying to ignore the tearing) to see if the Xorg CPU issue goes away. I also haven't tried mplayer on a recording to see if it produces the same issue.
Given that there doesn't seem to be anyone else around that shares this problem I'd be equally interested to hear from someone that DOESN'T have this problem to see what the differences are between a working system and the setup that jafar and I have.
