"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.
