An innocent question that resulted in an excellent summation of the OpenGL vs Direct3D war from the mid-1990’s until now. It’s a well written and informative post that spells out how Microsoft caught up to OpenGL and eventually overtook the open standard through opportunism and the incompetence of the OpenGL Architecture Review Board.
The author also answered some age old questions like why NVIDIA video cards performed so well with OpenGL. He also provided insight on how catered Shader Models and exclusive OpenGL extensions during the GeForce 3 and Radeon 8500 days.
It was an interesting read to say the least.
