It was an interesting video indeed.
If you had a 30 FPS cap, you have one now (and need it removed).
If it was 900p before, it is 900 now.
The one I found most interesting was Sekiro. PS went checkerboard, Xbox went native. Yet the PS has a better frame-rate because of that.
Oh and clearly the best? 60FPS Knack.
Does the Xbox Series X works the same or, besides the auto-hdr mode, they have something extra?
