This bug is not a duplicate of bug 988079. This is a compiz bug since it appears with compiz even if the unity plugin is deactivated. With Unity2D now dropped in 12.10, the only workaround is to temporary unredirect fullscreen windows when starting a game. (thank you Daniel for the hint)
I want to add, that I'm having these performance issues even if I don't start the game in fullscreen. There is a framedrop of around 20% but the gaming experience is actually much worse because of the tearing artifacts (no effect if VSync is activated) and also the framerate being very uneven. As mentioned before, this bug is a regression since it appeared with 12.04 and is still present in 12.10. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/964788 Title: bad gaming performance when running compiz (nvida gt-240) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/964788/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
