Intel here: Bug #763005 isn't a problem (the animation is fast and smooth whether or not glxspheres shows low frame rates) and Option "TripleBuffer" "false" (with or without sync to vblank) doesn't fix it.
The low frame rates aren't consistent. Often (well, usually) immediately after X starts, glxspheres can manage almost 60fps. Some time later it deteriorates. I've seen the frame rate go as low as 20fps. Sometimes it recovers by itself, other times not.
Right now, glxspheres is showing between 24 and 35 fps. The system isn't under heavy load or anything - I've only got firefox running. And as a comparison, alien arena is showing 8-15fps whereas normally it can manage closer to 30fps.
