(Get the code!)
Note that overlays with only triple buffers will drop to half frame rate more easily. Because overlays/bypass requires the compositor holds two of the buffers much of the time. So performance is more like double buffering -- you either hit 60Hz or drop all the way to 30Hz.
But I thought NBS had switched to quad-buffering already? That would solve the smoothness problem at least (at the expense of higher latency).
I know all of this is unrelated to fencing issues, but definitely something to keep in mind.
