How much of the subjective interactiveness-feel of the desktop is at the
mercy of the X server's scheduling and not the cpu scheduler?
I've noticed that video playback is significantly smoother and resistant
to other load, when using MPlayer's opengl output, especially if
"heavy" programs are running at the same time. Especially firefox and
ksysguard seem to have found a way to cause video through Xv to look
annoyingly jittery.
