Stuff like this makes me sad that so few Switch games attempt a realistic visual style, as titles like this, Outlast II, and The Vanishing of Ethan Carter demonstrate the system can do beautiful realistic visuals when devs make the effort.
It also makes me wish Nintendo wasn't so weirdly adverse to using AA, the system can clearly do it quite well.
Sorry but if resolution can drop to 900p and even 756p I can't believe it's a better looking game than PS4 version at native 1080p.
756p is borderline last gen territory.
Both in the video and on Twitter John has explained that it's 1080p most of the time. That minimum figure will only happen during the worst case scenarios, so in practice hardly ever; for the majority of playtime you're looking at the same pixel count as PS4 just with more modern AA.
