Well, it does, sort of, if you are happy with one refresh every couple of 
seconds...

Are you sure? Mesa software fallbacks are quite slow. I tried playing kubrick 
on a remote session, and it was not playable at all.

On a local display, of course the animation is very smooth.

Actually, there is space for improvement with remote display performance for 
most games...

KGoldrunner is still slow, though it has improved, compared to the KDE 3 
version. Other games looked slower than KDE 3 version, last time I checked... 
If i recall correctly.
