"Xbox360 cannot run DX10, and confirmed what I said earlier about the extended functionality. The Xbox360 has unique features including memory export that can enable DX10-class functionality such as stream-out," said an ATI spokesperson. "From what we're hearing, Crysis will support DX9 with some sort of use for DX10 features. It's likely that those DX10 visuals can be replicated on the Xbox360, but it can't be properly called DX10."
