Why doesn't MS get enough credit for DirectX?
Every GPU innovation ever only exist because Microsoft kickstarted it through DirectX. Remember when GPU went from the separated Vertex and Pixel shaders paradigm to the unified shaders paradigm around 2006 ? That was because Microsoft rewrote their graphical API stack for WIndows Vista and the Xbox 360. NVidia and ATI only created GPUs that would work with the new API.
