Difference Between DX9 and OpenGl

[Bigpet]

For the longest time the OpenGL backend was the only renderer. The Direct3D one was only recently added because of some of the shitty OpenGL drivers on Windows.

The obvious reason is that OpenGL is available on all platforms whereas Direct3D is only available on Windows.

And the difference in performance shouldn't be big if people wrote decent drivers but AMD apparently does not want to or cannot spend those resources, so they decided to prioritize what most people use, Windows and D3D.

... on Windows. Many of those devices have OpenGL 2.0 drivers on Linux, it's not always a hardware limitation, sometimes it's just software.
