Finally, in an unexpected move, Microsoft also used the blog to quickly address the subject of AMD’s Mantle API, specifically saying that the Xbox One doesn’t support it nor OpenGL. The fact that Mantle isn’t supported comes as no surprise – Xbox One already has its own low level constructs versus the still in development Mantle – but we weren’t expecting Microsoft to comment on the matter since they aren’t involved in the development of Mantle. Though this unfortunately doesn’t shed any further light on the big question of just what Mantle adopts from the low-level programming constructs in Direct3D 11.x.
