This is just a guess, but is your software calling drawFrame() between calls
to pfdLoadFile()? Because of Performer's multi-buffering mechanism, it has a
hard time dealing with big changes to the scene graph at run time (it seems to
get worse as the scene gets bigger, as well). We've seen the same behavior
deleting a lot of stuff from the scene between frames.
If you are loading things between drawFrame() calls, try loading everything
before the first drawFrame() call and see if that helps.
Hope this helps,
