No, my card is an PCI-Express one, not integrated. And altougth the GS
is less powerful than the GT, it's only for a little (it's basically a
6800 overclocked to almost the clock speed of the GT). And it has 256
mb of memory.
I don't buy the texture-from-pixmap explanation; I remember that with
Beryl it was *orders* of magnitude more smooth than my i915. The
problem is Compiz Fusion and/or the version of X.org. It *could* be
the Nvidia drivers, but I doubt it.
Thanks for the comment, anyway.
