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?
