The framerate should be approximately the same as the monitor refresh rate. 243 frames in 5.0 seconds =3D 48.124 FPS 157 frames in 5.0 seconds =3D 31.300 FPS 155 frames in 5.0 seconds =3D 30.864 FPS But I'm pretty sure that vertical refresh is 60 hz! And gears are jerky (no= t=20 smooth at all). If I move mouse cursor over glxgears window FPS goes up to = 60.=20 And main problem is that keyboard events are also jerky, i.e. I press key a= nd=20 system receives press event in 0.1-0.5 sec or so (tested via xev). There's no such problem when composition manager is running (i.e. effects a= re=20 enabled in KDE) Is there any solution for this problem? It really annoys me.
