These muppets have no clue what they're talking about and it seems like half the people ITT have forgotten what the issues with XBX are.
The game not being native 4k and therefor a bit soft isn't the issue, it's this shit:
Warping/deforming textures everywhere as soon as you start moving the camera (and this also affects ground textures, everything you see) and I can't see this anywhere in the XB1 footage they've provided. The foliage/trees in the distance look a bit shimmery but not nearly like what is going on in XBX, the ground also looks kinda fine. I also don't see it in the raw footage
@alf717 provided (but I do wish he had not moved the camera as much as he did).
I'll wait for DF to take a look at it, but from what I am seeing it's definitely not comparable at all.
