Hi,

The only way I have been able to increase the performance is to crank down 
various texture related options in the games. I was able to get ut2004 
playable framerate wise, but I still get severe texture and model tearing 
errors. I have seen these on any system with an ATI card using ati's own 
drivers. In the end I cannot play ut2004, which is a real shame, and very 
aggrivating (damn you ati, make good linux drivers!!)

I think that due to the X300's low texture memory of 64MB, turning down 
texture options helps a lot.
