There's only one game (at launch) which I am aware of where the Pro actually outperforms the Xbox One X, and it's Ace Combat 7.
That game has seen 6 or 7 patches since its release so I highly doubt that's the case now, but when it was that comes down to optimization and nothing more. When equally optimized there's nothing the Pro can do that can out-render the Xbox One X, it's a computational certainty. Its GPU is of the same architecture but substantially weaker less PPC, its CPU is of the same starting architecture but underclocked and lacking the improvements Microsoft made to IPC. It has less RAM and 33% lower memory bandwidth which results in high resolution bottlenecking.
And you want to talk about Microsoft PR and being deceptive? Who sold you a 4K console that is averaging 1440p resolution with almost zero ability to actually hit 4K while the competition is averaging 1920p resolution with the ability to hit 4K in many instances? Who sold you a console with an extra 365 days of lead time that now has less enhanced games by a factor of 57 titles (437 vs. 494).
Oh Microsoft is talking out of their ass? Or did you not do the proper research? They outline their improvements, they list the scaling and what has changed. Where is the corresponding data from Sony?
