Radeon Performance Enhancement

Place these settings in your xorg.conf:

The RADEON driver (man radeon) supports the following options for the RV280 chip (which is found on RADEON 9200 boards). The default values are in red:

• Option "AGPMode" "1"
  (driver currently supports up to x4)
  
• Option "AGPFastWrite" "off"
  (only used when DRI is enabled)
  
• Option "BusType" "AGP"
  (if driver's bus type detection is wrong)
  
• Option "DisplayPriority" "AUTO"
  (set to "BIOS" or "HIGH" to fix tearing)
  
• Option "EnablePageFlip" "off"
  (turn "on" 3D page flipping for better performance)

The biggest wins would come from APGMode and EnablePageFlip. APGFastWrite may help DRI. DisplayPriority may help KDE. Don't use BusType unless the log shows the driver has selected a PCI bus for the card...

Note:- when playing with Xorg 6.5 I got X crashes with EnablePageFlip turned on.
