We don't need to force fullscreen to cause us to loose vblank interrupts whilst the processor is asleep (and so render very slowly). -- You received this bug notification because you are a member of Desktop Packages, 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 Status in X.org xf86-video-intel: Incomplete Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: I have an Acer AOD250(KAV60) netbook. On Ubuntu 12.10 with glxgears I get 50-60 fps, while on Lubuntu I get half that and sometimes worse. The odd thing about this is that when I start moving my mouse around it straightens up and goes back to roughly 55-60 fps, and once I stop moving the mouse, the performance drops again. I know the chipset and GPU isn't the best out there, but it shouldn't be acting like this(before, I was able to use Celestia with ease but now I get below 5 fps).
