I just have to talk about SAINT'S ROW IV.
I didn't even know this game got a Switch version, only got to know a couple of days agora due to the thread about it going on sale. I bought it. At first I wasn't surprised, maybe due to its art style. But particles effects did get me wow'd.
Then I searched it on YouTube to see if there was a DF video about (there isn't), and found this:
It's an open world 2019 game that doesn't run at locked 60 FPS on PS4, yet it manages to stay between 45-50 FPS on the Switch, and on more demanding scenes where it goes down to high 30s on the PS4 it's also at high 30s on the Switch. By this comparison alone I couldn't even notice any missing graphical feature on the Switch. It's impressive, particles, rain, reflections all look really good. Shadows too. By this comparison it just looks identical to PS4, maybe darker.
