FrictionalGames OpenGL Hero

About the guy that said Id uses OpenGL on the X360, that is not true even tough the new idtech5 engine is still OpenGL that is only on the PC and on the PS3, the engine on the X360 uses a similar render to D3D9 (dx9), why? Because the Microsoft console only supports directX.

That guy is me and I suggest you to use Google. John Carmack said in one of his interviews that they've been asked how they implement OpenGL games for Xbox360, and he said they're using an API which works similar to D3D.
