The fglrx driver is not known for its speedy 2D or 3D performance, but there are ways to improve it.


If you suffer from slow 2D speed it might help to set

Option		"XaaNoOffscreenPixmaps"

in the fglrx device section of /etc/X11/xorg.conf


If you plan to run Wine, you will need to tell fglrx to not corrupt the fs register. To do this, add the line:

Option "UseFastTLS" "2"

to the "Device" section in /etc/X11/xorg.conf. This supposedly causes about a 10% hit in opengl benchmark scores, but at least things don't crash. See also and
