Radeon ( "radeon" X11 driver )

Higher frame rate

Before applying this tip, make sure you are using the "radeon" X11 driver. As root, open the file ""xorg.conf"" with your favourite text editor ( Kate, Gedit or vi ...) which is located in ""/etc/X11/"". Now add four options to the Device section, without changing "BoardName", "BusID", "Identifier", "VendorName" so it will be like this :

Section "Device"
  BoardName    "Radeon VE"
  BusID        "1:0:0"
  Driver       "radeon"
  Identifier   "Device[0]"
  VendorName   "ATI"
  Option "AGPMode" "4"
  Option "AGPFastWrite" "1"
  Option "EnablePageFlip" "on"
  Option "BackingStore" "on"
EndSection

Now save the file and restart X either by pressing Ctrl+Alt+Backspace or by logining in and logining out. With Radeon VE, glxgears frame rate improved of about 35% (from 273 fps to 367 fps)

Please report the improvement you noticed here. To calculate your frame rate, run "glxgears" from the command line, and note the frame rate without resizing the window.
