I'm working on an autonomous navigation system based on the optical
flow. (Onyx RE^2, Performer 1.2)

Until now the algorithm, which is computing the next heading
direction isn't a real-time algorithm.
I have the feeling that Performer gets in trouble with the
synchronisation, if the application lasts a lot longer (here ca. 2 seconds)
than the framerate.

Does anybody have experience whether Performer can handle those applications
which last longer than the FrameRate?
Or is it perhaps better to use Inventor for this problem?

Or the other way round: synchronisation starts with the call to
pfSync(). Does the synchronisation sleep after the call to pfFrame
until pfSync is called again?
If that is true, I could call the appliation before calling pfSync or
after calling pfFrame, and there wouldn't be any synchronisation
problems?

Thanks in advance
