I'm not sure who you are trying to convince here. I have a very good idea of what Scorpio will be like, and I'm quite excited/ hopeful about it. Studios at MS offering smart graphical features like Dynamic resolution will only add to the quality of Scorpio games, not take away from it. Nevermind that, I'm not even endorsing the fact that MS should even target 4K. They could probably do amazing things by using checkerboard rendering, and even targeting 60fps. I am saying though, that I am very confident MS and 3rd parties will be able to hit a native 4k 30fps on Scorpio titles should they choose.
I have a lot of experience with almost every GPU and a large amount of the CPUs on the market right now, and I'd say I have a very good idea of how MS first-party games might perform on Scorpio, if they do indeed hit their 6 Terraflop GPU target for the machine.
Hell, boot up any of the UWP Win10 store games on a 6 Terraflop GPU, target 4k, and let me know what you find. In my experience, that usually means 30-40fps with cranked settings, on essentially every AAA title, with substantially improved graphical and image quality.
What exactly this 6 terraflop AMD GPU in Scoprio will actually turn out like is anyone's guess, but if it's a nice improvement over the RX 480, and can perform close to a Fury X, but with 12GB of GDDR5, then the system will be a beast, especially considering the success of async compute support on DX12 games. It will also likely be able to push true 4k quality textures, if it truly does have 12GB of GDDR5, which is something the PS4 Pro doesn't even seem to be trying to do for whatever reason.
