Why the hell would I downplay it? The tearing is horrible. All if you followed anything I have ever said, you would see how much I praised Rise of the Tomb Raider on the 1X. If you like, I can record a video from my phone showing you how bad the tearing is. And my TV is a high end Samsung 4K 9 Series.
And Digital Foundry specifically says that the Xbox One X version of this game does not meet the same resolution as the previous title. I doubt you watched the video at all since you have no idea where I got that from........
Xbox One X version targets a 2016p resolution. Go to the 11:00 mark in the video.
