[compiz] Xorg eats lots of cpu power when compiz is active

[Julian Sikorski]

As stated in topic. Maybe I have misconfigured something, because cpu
usage sometimes rises to as much as 40%. I am running git compiz, fedora
 core 6, nvidia fx5700 with 128 MB vram using 1.0-9629 driver and a
pentium 4 3.0E prescott cpu. Isn't compiz supposed to be
hardware-accelerated, and thus not hogging the cpu so much? Thanks for
the response in advance.
