Indeed. I benchmarked a few popular games, comparing performance between Metacity, Compiz and Mutter. In some cases Mutter causes performance to drop by more than half.

Are there any open bug reports for those of us who want to follow development on this? 0. http://mail.gnome.org/archives/gnome-shell-list/2009-August/msg00045.html -- Cheers, Sven Arvidsson http://www.whiz.se PGP Key ID 760BDD22
