https://bugs.freedesktop.org/show_bug.cgi?id=39202 --- Comment #28 from Siganderson <dj_def@xxxxxxxxxx> 2011-08-18 04:09:57 PDT --- I just booted a 2.6.38 kernel before that commit with these results: cat /var/log/Xorg.0.log | grep Pageflipping [ 12.197] (II) RADEON(0): KMS Pageflipping: disabled cat /var/log/Xorg.0.log | grep SwapBuffers [ 12.197] (II) RADEON(0): SwapBuffers wait for vsync: disabled vsync in kde desktop effetcts settings is unticked (disabled) glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 9872 frames in 5.0 seconds = 1974.097 FPS 10436 frames in 5.0 seconds = 2087.059 FPS vblank_mode=0 glxgears ATTENTION: default value of option vblank_mode overridden by environment. ATTENTION: default value of option vblank_mode overridden by environment. 10005 frames in 5.0 seconds = 1999.635 FPS 10654 frames in 5.0 seconds = 2130.778 FPS the max fps is 60!!! but if I enable vsync in kde desktop effects settings or doing "vblank_mode=1 kwin --replace" the fps goes to 100!!! In these conditions vblank_mode=0 glxgears and vblank_mode=1 glxgears have the same output (2000 FPS). This has no sense. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
