"However, it seems to me that performance is still a little better when *not* using twinview."
This is not surprising. Regretfully compiz does have to use the detected frame rate for some (very few) things even with the fix. And if the frame rate reported by the driver is still wrong (TwinView enabled) then some things might still be slightly worse performing than with TwinView disabled. The solution should simply be setting the correct refresh rate in CCSM (Composite Section): Detect Refresh Rate = OFF Refresh Rate = the correct refresh rate of your monitor -- 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/92599 Title: Incorrect (low/stuttering) refresh rate with NVIDIA driver To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/92599/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
