Which is why I said *something* is chewing up CPU in the rendering
pipeline someplace.  It could very well be the driver, one thing that
might help would be running the demo in "flat texture" mode ... you can
turn that on from the console, but I don't know if it's possible in the
config.  If there is a significant jump in FPS then it's a driver/card
issue I would think.

Linux drivers are pretty new for ATI, so it's possible.  Another
possibility is to use Xig's drivers and see if there is a difference. 
They have demo drivers I seem to remember, it may be worth trying it
out.  Like I said nVidia card users seem to get by with similar systems
and have higher frame rates.
