They said it runs 810p-900p dynamically scaleing (docked), and spends more time at 810p than at 900p. (same with handheld mode 600p-720p)
Still runs 30fps (almost always), but now has AA.
It looks good imo (visually), for a pikmin game.
Not just for a Pikmin game, its easily one of the best looking Switch games. I'd say it's in competition for No.1, the somewhat low resolution is the only down side.
Luigi's Mansion 3 is cleaner but also less ambitious
Thats a matter of tastes.... I guess.
I think theres alot of games that look visually more impressive than Pikmin 4, on the switch.
Super Mario Odyssey, Paper Mario The Origami King, Dragon Quest XI S, Final Fantasy 12 - The Zodiac Age, Octopath Traveler 1+2, Persona 5 Royal , Mario + Rabbids games,... ect ect.
It comes down to art style, and preferances I think.
But pikmin, while looking good compaired to older pikmin games, just doesnt wow me at all.
I think unless your a fan of pikmin games, these improvements to graphics are just going to brush off most people.
