Buffer size = width * height * colour depth
(could be a bit off with that, bit might kick start someone into posting a more accruate answer. how to calculate the size of the z-buffer, i'm not sure.
Texture size = (width * height /8)* bit depth
Everything, textures, meshes... etc etc, is loaded into RAM first, then transfered over to VRAM when it appears in the viewport, at least in blitz anyway. However, nothing is unloaded until VRAM is full and it starts swapping in and out. Must be a optimsation of some sort :o)
