Setting all the view offsets to 0 I was able to prove that the position/rotation matrices generated on the model and the camera are numerically identical. Here's a sample from the dump:

If you look closely you'll see that the numbers in sync. This is only a couple of iterations, but the values don't diverge over time either. With no offsets what so ever to either the model or the camera the jitters are still there (I modified a model in order to observe the jitters at 0,0,0 offset). The jitters are also there in "Chase View" so it has nothing to do with rendering the cockpit in a seperate ssg root. This tells me the problem is most likely in plib, or at least plib is where we send these numbers.
