steven: hi,
i installed the fglrx driver on a shared-memory system, with a 64-bit processor. xine was so unusable it was unreal: the framerate was measured in seconds per frame.
it looked absolutely great, though, with the anti-aliased fonts.
when i switched to the xorg ati driver, performance immediately went through the roof: xine was down to 17% cpu.
fglrx uses far too much memory, and uses it very badly.
it would be fine on a system with dedicated ram for the graphics.
