Hi, I have 2 machines with ATi cards; my main machine with ATi X1900XT and my test machine with ATi 9500Pro. I have installed both cards as per these instructions: http://www.desktoplinux.com/articles/AT7527984757.html (which were very useful by the way) and now I have 3D working.

The only thing is when I run glxgears I am getting just over 300fps on my test machine and 700fps on my main machine. Does anyone know of any way to improve this to where it should be?

Main:
Asus M2N32 SLI Deluxe
2GB Kingston 667 DDR2 (2x1GB)
ATi Radeon X1900XT
AMD 4600+ Dual Core 64bit AM2
Viewsonic VP930 19"

Test:
Gigabyte GA (something or other)
Samsung 1GB DDR 400
ATi Radeon 9500Pro
AMD 3000+
Daytek 15"
