In our original analysis of the PS4 Pro edition, Capcom told us that the game rendered at 2240x1260, with additional lighting enhancements. Since then we've heard reports of a different number being used on Pro's 4K output mode. YouTube channel VG Tech
in particular dissected the most recent patch 1.06 on PS4 Pro, finding a 3200x1800 resolution with what they believe to be checkerboard rendering.
We've approached Capcom for clarification and will update should a response arrive, but those stats hold up in our tests, which also suggest 1800p rendering - though there's a big question mark over the use of checkerboard rendering. The fact is that the stippling artefacts you'd associate with this technique are very well hidden behind the game's waves of post effects. In motion, the signs just aren't there; but it would explain how such a jump from 1260p is possible, if true. Checkerboarding or not, the good news is PS4 Pro's results are
visibly upgraded next to a regular PS4's 1080p, and it's a good mode to have available if you own a 4K TV.
