     I am working on a closed-loop application that uses Performer on a
     Reality Station running IRIX 5.3. I have some questions relating to
     frame control on this single CPU platform:
      
     I am running at a 30 hz frame rate with a PFMP_DEFAULT processing
     model and would like to use PFPHASE_LOCK. Since APP, CULL and DRAW
     become a single process, it is not clear to me if I will get the phase
     type I want. Can I really get phase lock behavior out of a single
     process or do I need to force it to use an MP model?
      
     If I can, then I would like to initially control which vertical
     retrace Performer declares a frame boundary. Unfortunately, I have no
     idea on how Performer decides this. Does anyone know how this works
     or/and if this is possible ?
      
     Thanks,
