"I loaded a 3DS model with about
2800 faces (~1800 rendered at any given time) and when I try to move
it at all (rotate in the render event) the frame rate drops into the
single digits.  I was hoping a different format would help. "

I was hoping someone could comment on this.  I was under the
impression that away3d should be able to reasonably handle up to about
10K faces.  I would think 2800, and only 1800 rendered, should be no
problem and not drive my FPS below 10.  I can post my full code later,
but for reference now, it is a very basic example with stage quality
set to low, no lighting, no background, and the only motion/object in
the scene is the model being rotated in the render loop.

Would a different model format other than 3DS potentially operate
faster?  Are there other things I can do to increase performance?
Please don't say "decrease polycount" because I thought that this
polycount should be easy for away3d.
