I already have "unredirect fullscreen windows" checked (but I don't think should affect glxspheres in any case since it isn't a fullscreen window).
After a complete system reboot I can sometimes get ~60 fps in glxspheres. But it gradually (or some cases, suddenly) regresses. I have noticed that when it runs slower, both glxspheres and compiz take up less CPU time: 60 fps => glxspheres = 20% CPU / compiz = 14% 45 fps => 16% / 11% 40 fps => 11% / 8 % ie compiz has decided for some reason to work less hard, resulting in laggy 3d. It sometimes goes back to 60 fps all by itself without a reboot. For instance, just now I checked 'Detect Refresh Rate' in ccsm/General Options and it went from 40 back to 60. (I had tried setting the refresh rate to 60 Hz in case the detection code was faulty, but I can't say that it made any difference.) -- 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
