Running Ubuntu Jaunty, the prerelease fglrx (8.6) on a Vaio VGN-FW21M (2.4GHz Core Duo, 4GB RAM) and a Radeon HD Mobility 3470 (256MB VRAM).
2D performance is abysmal! I can actually see window redraws when switching between applications. Using compositing in metacity is not an option, as basic operations become unbearably slow.
Should I not expect better performance from this driver, or may there be a bug or issue I'm running into?
xorg.conf is a clean one generated by aticonfig --force --initial.

Performance when using "ati" is just as bad, or a bit worse.
Clues?
