Hi,

The basic problem is - suppose I want to show a series of models,
so that each model is shown once per frame in order. I can do this by
putting my models under a pfSwitch and changing the value of the switch
once per frame in my app, or I can put the models under a pfSequence.
I understand that pfSequence is controlled by time intervals, so that asking
for "once-per-frame" is dependent on the frame rate.

    1) Will I get better performance by using pfSequence?
    2) What (if anything) is pfSequence doing behind the scenes which is
       different from my using pfSwitch (assuming that I changed the switch
       values in my app using the same time intervals which pfSequence does)?
    3) If I wanted to Is there a way to guarantee that each model will be
       shown once per frame, using pfSequence?

Thank you,
Erik Brisson
