    What are these?

    Does the HD4890 have all of them?
    Cuz in DXDiag video settings I don't see the OpenGl disable or enable or w/e funcionality while I do see the other 3. But does it still have openGL even though I don't see it?

    BTW for AOE2 to work for my pc I have to disable DirectDraw which also disables Direct3D. It's a 2D game. Will it work if I just disable Direct3D I think DirectDraw speeds up 2D acceleration or something. Correct me if I'm wrong. Thanks.

    OpenGL: A method of producing graphics, usually for games. Open-source.
    DirectX (also known as Direct3D): Another rival method of producing graphics, usually for games. Owned by Microsoft.
    DirectDraw: An antiquated method of producing graphics, unlike OpenGL and DirectX, designed strictly for 2D rendering (e.g. old primitive strategy games, your windows desktop), not 3D (full-on games like FPS and modern RTS)
    AGP Texture Acceleration: Relates to AGP technology, which is no longer used in most PCs (PCI Express replaced it)

    Age of Empires 2 doesn't work with Direct3D enabled because it's old and not really compatible with newer versions of Windows. You shouldn't have any performance issues with it, however.

    I had the game crash several times until I disabled Direct3D.

    My GPU does have openGL does it.

    Oh then why do I see the AGP Texture Acceleration in my List in DXDIAG. Should I leave it enabled? Any difference? Thanks.

    because Dxdiag is pretty outdated really. All modern GPUs have OpenGL support.
