Remember the dx12 secret sauce for xbox one
This will be cloud powered direct x 12 !
More seriously, de-noising is great for still images, but even the best algorithm will show pretty big movement artefacting on low sample images (you can see it in the shadows below the moving cars), enough that it is very distracting. Also, as you can see in the example, also a lot of fine details is lost.
This is nothing against their implementation, de-noising on moving images would require some kind of temporal pass, in a game that would probably mean rendering a couple of frames in advance to avoid this, which in return would force some level of extra input lag, because you would see the game "later".
Anyways, it's interesting, but I don't think it's directly related to xbox (even tho they are certainly looking into that kind of thing).
They should spend more time into Phyisics like this:
or scale physics (no cloud):
no matter tehnology , is game will be shit it will be shit with ray tracing too.
Raytraced shit is the shit!
