Hi,
I thought I'd share these tweaks to improve 3D game performance for RadeonHD cards. Maybe it's of some use to others.

My xorg.conf:
      Code:
Section "Device"
    Identifier "Radeon"
    Driver     "radeon"
    Option     "ColorTiling"     "True" # not sure if this does anything
    Option     "ColorTiling2D"   "True" # this is currently turned off by default
    Option     "SwapBuffersWait" "False" # this might cause some tearing though I don't see any
EndSection


Add the boot parameter radeon.pcie_gen2=1
Start your game with
      Code:
vblank_mode=0 ./name_of_the_game


For me it changes the frame rate from well below 60 fps to well above 60 fps in Nexuiz.

Cheers,
hrs
