Performance improvements on X600

[Marek Wawrzyczny]

Hi all,

I use the r300-driver (with xorg-server 1.3.0.0 branch) and xeffects overlays 
on Gentoo which appears to pull sources from the latest git masters branch 
(I'm a bit weak on git terminology).

As of 22/06/2007 21:00 AEST, compiz desktop seems to have received a 
significant performance boost. For example, the cube effect which usually 
taxed the CPU at nearly 90% (in performance mode) is now almost insignificant 
(8%-15% with CPU utilization in the powersave mode!) which leads me to 
believe that something must have changed in the radeon driver or drm in the 
last 48 hours to offset most of the work onto the GPU. Impressive.

I also have a quetion about the OpenGL depth feature for the r300 chipset. At 
present it's not supported. This causes any OpenGL window Is there anything 
users can do to help bring this feature for the r300 chipset?


Many thanks,

Marek Wawrzyczny
