Default FC6 Compiz NVidia 9626 CPU Usage HIGH

Hi all,

I just wanted to get a feel for cpu usage. At the moment my cpu usage is rather high with Compiz on.

Athlon X2 3800+

Note these are reported by TOP, not sure where the second core is though
Dragging windows, 10%-50%
Resizing 10%-50%
Playing Video on XV (xine,mlpayer) 40%-60%
Playing Video on opengl (xine) 10%-40%
Playing Video on opengl (mplayer) 40%-60%
Rolling the Cube Desktop 10-30%
Firefox Playing YouTube Video's 10-50%
FireFox with anytype of animations 10-50%

I just wanted to ask what are you's getting? I've heard a few say that compiz doesn't use any extra CPU.

The values I have seems rather high for what my machine is capable of....

You'll need to do a comparison to be fair - just reporting the "perceived percentages" by looking at top in one configuration doesn't allow us to come to any conclusions.

How about installing a lower rev driver and comparing - ahh but you're running compiz on aiglx. What about dropping aiglx and comparing against a lower rev driver without compiz?

Just to add another pin-point statistic: I run FC4, 8774 on a dual opteron 252 (2.6 GHz) in 64 bit mode. Dragging around a full screen thunderbird window loads the machine from 53-64% - this is running standard xorg 6.8 ( no compiz ).
