what if u have a slope so that there is ground and sky in both halves of the screen???

Well if one is drawing the sky and one is drawing the ground then it makes sense to have one having 256MB of sky textures and one having 256MB of ground textures. If they both have 256MB of everything then this is very inefficient, so my assumption is that they have a 256MB framebuffer of what they are working on.

I'm not 100% on all this though it has to be said, good question posed.
