Hi, I noticed recently that fullscreening flash video's from youtube on my 1920x1200 monitor leads to a less then optimal experience, looking at the video info right click menu (only available with some movies for some reason) shows many dropped frames. Switching back to 2.6.34.6-54.fc13.x86_64 (+ using upstart for the cgroup mountpoint thingie) makes the dropped frames go away. I also tried using upstart with the 2.6.35.4-12.fc14.x86_64 F-14 kernel, but the problem stays then proving this is not systemd, but a kernel issue. I suspect it is kms related. My system uses a ATI Technologies Inc RV570 [Radeon X1950 Pro], with a nVidia Corporation MCP55 PCI Express bridge. The frame drops seem to happen in bunches, for 2-3 seconds everything is fine and then 10-15 frames all get dropped, then 3 seconds good again, etc. Regards, Hans
That's perfectly normal, because we have a bunch of debugging options turned on in that kernel. (You're running what will be the -debug kernel for F14.)

Ooh, I just did a local build of the f14 kernel with the debug options disabled and you're right. Quite amazing, in some tests I saw xorg cpu usage go from 20% to 70%, I never would have guessed the debug options could make such a huge difference in certain circumstances. Regards, Hans
