Why so many checkerboard comments? Did I miss something or did 2/3 of the titles hit true 4K without optimization, and the rest of them get there with optimization (by implication)?
I think because of the E3 "true 4k" talk and labels in the video in MS conference and DF foundry shows that it was a lie and stuff like Assassins Creed is also checkerboarded like PS4 Pro that MS of course ditched.
You can expect 1st party stuff to hit native 4k, especially if it already runs at 1080p on base xb1.
