I missed your original post, but recently I was floored to see what a
difference switching video drivers.  I have an nVidia based card that
was using whatever default ubuntu drivers ubuntu had selected, and
installing the nvidia drivers from the nvidia site made so much of a
difference, I still can't quite believe it. 

Dunno if this helps any.
