Apparently the lack of render acceleration is the main culprit behind my Xorg (Fedora 7) 2D desktop (no beryl/compiz or compositing going on) just not being that "snappy" -- compared to an NVidia card or the same Radeon in Windows.

I have a 9800XT.

Does anyone know if the fglrx supports RENDER acceleration? ("RenderAccel")

The open source driver does not support it on the 9500/9700 cards and above unfortunately.
