I can confirm that CPU usage drops significally when vsync is disabled. To be
specific:
Vsync enabled: When computer is completely idle compiz cpu usage is 1-2 %
When dragging the terminal window gently compiz cpu
usage is approx. 30-35 %
Vsync disabled: When computer
Thanks Florian. It sounds like your graphics card and driver is so fast
that maybe compiz is rendering multiple frames per physical frame.
That's unusual but I can imagine it might be possible with fast graphics
and the new compiz rendering method in 12.04.
Can anyone else confirm the CPU usage dr
With the rhythmbox window open and rhythmbox playing a song (and the
slider slowly moving from left to right), but with the rhythmbox window
_NOT_ visible, compiz consumes ~10% CPU constantly (Firefox at full
screen, two gnome terminals [top & dstack] in front of it).
dstack seemed to indicate tha
Oh yeah, never been under 10% at idle.
With Gnome classic I got 2%, and that's way better when playing a video or
moving a window.
Please fix this asap, I think that unity in 12.04 is better than previous
versions, but this problem is ruining the user experience.

Same problem here.
Compiz don't use a lot of cpu idle (2% constantly), but the smallest action

A simple tab in chrome whith a notification animation takes 50% of the cpu
(because of compiz), a simple tab changing, a simple scroll, a simple dash
open...
In Ubuntu 11.10, compi
For me this seems to be a problem ~40% CPU while actively using browser,
and the same while away from the computer if I left the Facebook tab
open. Closing the Facebook tab reduces the compiz CPU significantly.

Hello,
i also have recognized the same behavior. My load-level at idle goes not under

With 11.04 and Gnome i has about 0,0x.
Also the fan runs now more frequently.
It runs on a Dell Vostro 1510.
