what? DirectX is a Microsoft API and only available on Microsoft platforms. For everything else, there's OpenGL. PS4 version runs on a variant of OpenGL 4.4 (which is actually ahead of DX11) with updated shaders. When they do add a Mac client, it'll be using OpenGL shaders similar to the PS versions.

That's not what I mean. I'm saying games are programmed in DX11 and they turn off features to "emulate DX9". Kind of like how you can use a modern engine to make a "retro game"
