    OpenGL in danger

    Published at 10:11   Category OpenGL  

    See this OpenGL Discussion :

    Microsoft’s current plan for OpenGL on Windows Vista is to layer OpenGL over Direct3D in order to use OpenGL with a composited desktop to obtain the Aeroglass experience. If an OpenGL ICD is run – the desktop compositor will switch off – significantly degrading the user experience.

    In practice this means for OpenGL under Aeroglass:

    • OpenGL performance will be significantly reduced – perhaps as much as 50%
    • OpenGL on Windows will be fixed at a vanilla version of OpenGL 1.4
    • No extensions will be possible to expose future hardware innovations

    It would be technically straightforward to provide an OpenGL ICD within the full Aeroglass experience without compromising the stability or the security of the operating system. Layering OpenGL over Direct3D is a policy more than a technical decision.
