My two cents worth: Poser 5 can do well in producing a static picture, but animation with the raytrace renderer is a lost cause. With a very potent system, you may get 200 frames before lock-up....and there is no retrieval of rendered frames. It was a lesson learned, and that is never, never buy untested software. I've heard that a new patch is on its way, so I can only wait and hope that they will address this problem.
