Does disk size not also come into it? The xbox textures and not as high a resolution as the blu-ray disked PS3 ones. 2gb of graphics mods, that's a lot a lot of memory if even the core game is only 3 times that. I only have the xbox version, I enjoy it immensely. Bethesda didn't do anything 'wrong', they did exactly what they wanted to do, and if modders can improve it great, but they can't exactly 'fix' it, as nothing was really broken.
