This thread has predictably enraged many a fanboy on either side of the console fence.
I'm an XBone owner, very much looking forward to the X, not a Sony fanboy.
I've read through this with my initially skeptical eyes saying things like "Phil always said Devs could do what they like, this isn't misleading at all!", but having read through this thread I was wrong.
The Xbox One X can hit native 4k on some games. We don't know how many but their first party stuff will most likely aim here.
As mentioned their policy is to allow 3rd party devs to utilise the power of the new console anyway they like, not mandating a native 4k resolution.
The OP shows a post that essentially explains what MS's description of 4k means, including dynamic resolution and checkerboard rendering. This means that when you see 4k on a box, it could use any of the above. They will likely specify whch games hit Native 4k to blow their own trumpet.
The issue people are having, and it's a valid one, is that Phil turned around and said that the X isn't competing with the PS4 Pro, because it isn't a "True" 4k machine.
Well that isn't true,if we take True to mean Native then the PS4P has several games running at True 4k, while many others use checkerboarding.
With that in mind how is the X1X different? It can also render games in native 4k and with its increased power will likely do it more often than the PS4P, but it also uses dynamic res and checkerboarding on stuff like 3rd party games. Phil was incorrect.
The marketing of X1X seems heavy on the True 4k mantra, which by itself isn't a lie, but stating it's the only True 4k console out there is.
