[Bug 861061] Re: compiz 3d performance regression

 

I tried turning detect frame rate off and setting the frame rate
manually to 120 (my monitors both report 59.9 or 60 Hz refresh), but it
hasn't helped. Sync to VBlank doesn't help the glxspheres framerate
either. It really is most odd, because up until yesterday it would quite
happily run at 59.x fps, whereas now it struggles to get 29-34 fps. If I
detach the external monitor I can get 40-45fps, but it still isn't
anywhere near 60.

I also run ironhide and if I run glxspheres through the nvidia card back
into compiz running through the intel card, I only get 50-60fps, whereas
before I could get 100-120 fps. And in metacity I can get over 200 fps.
