Dear mike-the-soon-to-be-enlightened

It sounds a lot like you are not doing a pfApplyTex on the textures.

Do a pfApplyTex for every texture in the database on the first time
through the DRAW process.

If they are all really sharing the same texture map then you ought to get
just one glitch on the first frame (when Performer does the pfApplyTex
on your behalf). So it looks like you are also failing to share the
textures between all those objects. You didn't say what you are using for
a loader.
