It doesn't expose the shader ISA, it doesn't expose the command stream format, it doesn't expose the register sets. Of course, none of those are important. The important bit to expose are exposed. IE: The memory-model of the GPU. CPU memory space vs GPU memory space, such as Residency: https://msdn.microsoft.com/en-us/library/windows/desktop/mt186622(v=vs.85).aspx https://msdn.microsoft.com/en-us/library/windows/desktop/mt1.... Indeed, the ability for C++ to create abstractions that can track memory spaces in DirectX is proof positive that C++ has useful features applicable to the OS developer. https://msdn.microsoft.com/en-us/library/windows/desktop/mt613239(v=vs.85).aspx https://msdn.microsoft.com/en-us/library/windows/desktop/mt6... ------- Note that both CUDA and OpenCL support C++ features as well. The RAII feature of C++ alone is a huge benefit to anybody tracking what bits are where in OS settings. Have you tried to use C++ in the last 10 years?
