I too have this issue. Radeon HD 7970 and Ubuntu 12.10 with the latest fglrx at the time of this post. Only way to minimize the lag is to disable sync to v-blank and screen tearing in CCC.
It's a very serious performance issue. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/763005 Title: fglrx driver + compiz's "Sync to Vblank" makes display stutter/slow To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/763005/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
