Default Re: Poor 2D Performance

Various reasons, possibly.
nouveau might have more efficient software fallbacks, avoiding most migration ping-pong.
Maybe nouveau can tile large pixmaps into multiple smaller ones (intel's driver does this in some cases, too).

I have to say I haven't experienced the ridiculously bad 2d performance some people are reporting. It's quite the contrary with recent drivers, in general they provide excellent XRender acceleration, so I'm not sure what's going wrong.
