Yeah, but it's a single quad representing how many polygons castin shadows? The sphere and the torus must be a lot. Anyway, it wouldn't run on my system (relief mapping) but it rendered at 985 fps ... ;) Anyway, I think bumpmaps have their place ... for now and will eventually be replaced with ultra high poly stuff, which will be replaced with some form of voxel system ... some sort of organic configuration for graphics.
