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.
