Docked: native 1080p (but sometimes drops between 936p to 864p), 60fps locked.
Portable: native 720p (but sometimes drops to 1152x648), 60fps locked.
More details Like Real Time Shadows, character models, higher quality textures and more.
I thgt they actually said the resolution of docked are always drop down to 864P, except for some less complicated scenes? and same goes for portable mode?
No, they never said always, they said resolution goes from 864p, 936p to 1080p.
Switch has 720p screen so any resolution above wouldn't make sense, they said that resolution in portable mode goes from 648p to 720p, basically same like Zelda BotW in handheld mode.
