Uh, yeah, that's too what normal maps are used for. Silly me. But you could have said that it's the weapon of choice for DX9 then. ^_^
I don't know too much about the technology itself, just that it can be used to bring some really nice depth to textures. Much much better than any normal map could do.
Not sure how well it works on a full-scale with DX 9. Probably not too well, would be my guess.
Hasn't it been clarified that all screens are from the xbox version? Didn't OXM say that? Otherwise I'm 100% sure that all screens are from the xbox versions as the pictures are rather low quality hi-res (as someone mentioned).
Well, yes. I hope you're right that the PC will do this better. Both in term of "depth" of textures, anti-aliasing and more hi-res textures.
