   Very.  Partly because the hardware is very different.  Partly
because it has a different heritige.  NVIDIA's OpenGL was direct
rendering under Windows before the DRI existed.  NVIDIA's X-Window
direct rendering architecture was written to interface with
existing direct rendering OpenGL code used under Windows.
