    They going to talk about the second GPU been unlocked in the Xbox One with DX12?
    Or has the NDA been extended until E3 now?

    Very interesting video, congratulations. Seems DX12 will have significant impact on windows 10 devices. Once Xbox One will also use windows 10 my question is at which extent the benefits shown in this video are also applicable on Xbox One? Thank you very much.

    Are you high Josh? There isn't a dormant second gpu in the xbox one lol

    Yes there is mack,
    There is information backing up the 2nd GPU.
    And with the NDA, they can't talk it.
    Just have to keep waiting, but I've read today someone posted
    it's likely to be when Wind 10 is released.

    People say they Xbox One is weak 1.31TF, but the research is showing it's 2.6 -4.5TF range depending on layer unlocking.
    And DX12 has the unlocking keys.

    Not sure what crack & lies you are smoking, but there is no secondary GPU on either the xbox one or ps4 APU.

    @Josh Winters: Stop your trolling and grow up. This is not N4G or IGN.

    Really cool stuff, i don't suppose all these new features are in the current win10 build? when do you think they will be available?

    Also more generally, i think one of the hardest bits for people learning directx today is that the official docs and programming guides are a little light, is that something your're looking to to improve for windows 10? (at or close to RTM i mean, all though the earlier the better)

    To be honest, this new feature level 12.1 is a joke.

    That's only showing the top die. There are side image x-rays showing it's multi-layered. The NDA is still in place over the second layer.
    That's why it's currently only 1.31TF.

    Great work on the streamlining of the state machine, and great to see the reduced cpu utilization.
