Is all your code up in the thread? There are a decent group of people here, might be able to help, Dave will have to want to help, and recent events may not make him inclined to do so.
So, this works as designed if there are fewer than 150 objects in the scene (refresh my memory, is the scene defined in your mind as on screen)?
What kind of hardware are you on, out of curiousity?
Also, not that it matters much, but are you working from released code, code you have been personally working on, or the fs2_open build from the warpcore CVS?
Question for the group: Has anyone else tried this? A community project only works if we're working together
