I also see exactly the same behavior with Oneiric's Compiz and Radeon HD 3200 (AMD 780G chipset's integrated graphics). Compiz is a lot slower/laggier than it was in 11.04.
Testing with glxgears (leaving the glxgears window in its default size) on latest Ubuntu 11.10: Compiz is at around 33-42 FPS Mutter is at a stable 59.xxx FPS Ubuntu's 11.04 Compiz was also at 59.xxx FPS (the screen's refresh is at 60 fps). There is a chance that the fix in: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/763005 solves it, but i don't have a way to test it until a PPA of the fix for Oneiric is build. I think that this is a very important regression because for the systems that it affects, Compiz/Unity becomes unbearably stuttery/slow. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/861061 Title: compiz 3d performance regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/861061/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
