"Other thing that occurs to me is that this is rendering camera views directly to a texture (or if not directly it's shifting it a lot faster than CopyRect() ).
Actually if you look at the castle demo source, it's up to YOU to render each of the views and then you copy it to the cube map texture with copyrect.
So it's not any faster than copyrect. DirectX 7 and 8, and maybe 9 have no way to render directly to a texture.
