Are DX10 cards backwards compatible with DX9?

    Im sort of confused on this matter.

    The net has conflicting answers as to the real answer to this question.

    I know that a DX10 card can play a DX9 game. The question tho is, does it nativly support DX9 or is it via a software layer or "emulation".

    If its the later, could this not be atributed to a loss in performance while playing DX9 with a DX10 card?

    This is even more confusing when you consider Vista. Maybe its Vista that has these issues and not the DX10 card itself.

    Anything to clearify would be great.

    Hi, I have vista with a 8800gts and I can play all games. without any problems. No FPS drop. I think directx9 is embedded in the DX10

    In XP: hardware support, and no loss of performance. At least, I don't hear 8800 owners complain about the crappy performance in XP, do you?

    Considering Vista: it's Vista and not the card itself ;)
