When I set pfPhase(PFPHASE_FLOAT), it seems to respond as if I've
set pfPhase(PFPHASE_LOCK).

I am nowhere near my target frame rate - I miss the frame boundary
every time. With PFPHASE_FLOAT, Performer should wait only until
the next video retrace to start CULL/DRAW. It doesn't. It waits until
the next frame boundary. (That's what PFPHASE_LOCK is supposed
to do).

I know the above from looking at the stats display. Along the very
top, it says "FLOAT". But the thin dotted horizontal line corresponding
to "app sleeping in pfSync" stretches to the next vertical green line
(frame boundary) even if it crosses red lines on the way (video
retraces). Also, I can _see_ it at very slow frame rates.

Is this a known bug?
Any advice?
thanks
