For a check you can save the scene graph of your loaded flt file with the example program
complex.C with the option -w.
I think the scene graph will contain a pfSequence node that the flight loader uses to
make the animation. At load time it sets the animation rate of this pfSequence based on the
PFFLT_FRAMERATE settings.
If you want to change the rate you have to find the pfSequence node and change the settings
yourself. Find the node name or the node type.

P.S. Is it possible to remove the 'strange characters' in your email 'From:' line.
I use a plain text based mail tool.
Maybe you can do it for the performer mailing list only.
