That's not true. Direct3Ds up to and including 11 are the same way.

  Not really, COM instances for each 3D concept are created and passed around. There isn't this thing of binding/copying stuff into global state.

    What about this (only one example) ID3D11DeviceContext::IASetVertexBuffers https://msdn.microsoft.com/en-us/library/windows/desktop/ff476456(v=vs.85).aspx https://msdn.microsoft.com/en-us/library/windows/desktop/ff4... It's no different from manipulating the opengl context.. Also google bindless opengl

      It's very different in practice. D3D11 contexts are explicit, real objects that you create, manipulate, and pass around. They can be properly and realistically handled in multi-threaded code. OpenGL contexts are opaque and global, and properly handling them in multiple threads is a nightmare. Multiple OpenGL contexts is also very different in functionality from multiple D3D11 device contexts.
