It took me about 3min to render. The face counts are pretty low in this scene. I have scenes that have taken me about 8min to render. I'll probably just use the raytracer in blender for now on since it takes me about 30seconds to render the same scene in that engine.
I used to use it ages ago. It's very cool, although 8 minutes is a lot shorter a rendering time than I got! I was working with an Atari ST, and scenes were taking 24hrs or so to render.
