Default Bad performance on GeForce 8600M GT with lateset driver and recomended tweaks

Hi,


I'm running Gentoo x86 on a 2.6.25 kernel with nvidia driver version 177.70 and a GeForce 8600M GT (+ Gnome and Compiz Fusion). When I apply all the performance tweaks (http://www.nvnews.net/vbulletin/showthread.php?t=118088) for xorg.conf and then use
Code:
nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1
I experience several things:

Some things like re-sizing gnome terms and using the window switcher are _greatly_ improved.

Some animations like simple Avant Window Navigator dock re-size are _really_ slow, like a 1 second animations takes nearly 20 seconds.

If I revert to
Code:
nvidia-settings -a InitialPixmapPlacement=1 -a GlyphCache=0
then the situation is reversed (back to the norm). Animations are generally fine, and re-sizing gnome terms is once again very slow.


I notice that when I use
Code:
nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1
the thing that seems to be slowing some of the animations down is very high X cpu usage.


I have attached a bug report. I would very much like to see this fixed, so if I can provide any further info or help in any way please let me know



Cheers,
