Questions:

So glxgears runs at 62fps, and I think I saw something about it's now
locked to vsync. So that's fine I guess. But that doesn't explain why
WoW runs like crap. OpenGL is non existent, either X doesn't update the
screen or it's renders tons of crap (this is with WoW). I have tried
every version of wine/WoW that I could confirm working (on ATI/Nvidia)
so I'm pretty sure that leaves the intel driver or X.

Other then that compositing and junk works fine, some stuttering but
nothing really annoying. Mind you mplayer hates it when I have
compositing on, but xv is the only video output driver that works well
with 720p and up. But I guess they don't need the horse power that games
do.
