Dag, thanks for the reply!

I'm using a driver I got directly from Nvidia. Are you saying that some
of the re-packaged nvidia drivers are better (in other ways than that
they make use of the distro's packaging, I mean)?

I think I already did but I'll go check again in case I missed something.
I assume you mean the Centos wiki...

Sorry, no can do. It's a dedicated card with 64MB. I'm thinking of
picking up something less obsolete, though. I probably ought to do it
soon, as it looks like AGP cards are now being relegated to the low-end
and it's probably getting worse as time moves on. My display is "only"
1280x1024, so that 64 megs may not be too terrible a limitation.
performance isn't a big issue (except for resizing windows which sometimes
is fairly painful--I read somewhere else (possibly on compiz' own site)
that this is due to something other than compiz but right now I don't
remember the details.) I can rotate the cube quickly and easily, and
the jello windows jiggle nicely, assuming one likes jiggly windows.
