Ah, that's broken - we are not using vsync. Presumably it failed to get permission to open /dev/dri/card0 and so is using indirect rendering (which does not respect vsync). Try "LIBGL_DEBUG=1 glxinfo" and see if (a) reports indirect rendering and (b) why. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1087582 Title: [gen3] Bad GPU performance whilst CPU is in deep sleep To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1087582/+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
