Read the information in the link about how DirectX became the de-facto standard (sections 2 and 3).

The link seems full of MS distrust rather an objective review. DirectX overtook OpenGL thanks to the mess started by GPU manufacturers that introduced their own proprietary extensions and ARB sleeping. https://softwareengineering.stackexchange.com/a/88055 https://softwareengineering.stackexchange.com/a/88055

DirectX was simply a better API. Game dev is hard enough without dealing with OpenGL's jank-ass state machine, which adapted to vertex and pixel shaders about as well as the Unix process model adapted to threading. One of the great tragedies in 3D graphics is that Project Fahrenheit never got off the ground. Under Fahrenheit, OpenGL would be put out to pasture, DirectX would become the new low-level standard, and a higher level scene graph API would be built on top of DirectX.

  True, but that was not the reason it was abandoned initially. Back then multi-core CPUs were not much of a thing yet. The reason it was abandoned is because people were told OpenGL on Windows Vista was going to be implemented through a compatibility layer that was going to be slow.

    By the time Vista came around, virtually no one except Carmack was seriously targeting OpenGL.
