True. But by the radeon(4) man page on the test system, the closest thing
would be NoAccel. Testing the radeon driver, with DRI disabled, the
fglrx-specific options commented out and "NoAccel" "on":
2D performance is a misnomer.
glxgears: ~683 FPS
If you, Chris or anyone can think of a set of options to make the radeon
driver more equivalent to the fglrx driver, post 'em and I'll grind the
gears.
