I see no reason why when the Switch toggles between docked output and portable output it could be a switch between 60fps and 30fps. The game could be still generating 60fps internally but only outputting 30fps on the portable screen. I understand it can't switch between higher and lower quality assets because that would require a long pause between switching but m pc will happily toggle between 60 and 30 fps screen modes on the fly without problems. Combined with dynamic resolution which the nvidia gpu's tend to do very well, Switch, PS3 etc I would of thought that was a good possible solution. I really think the game experience will be much reduced if they don't maintain 60fps when docked. It's going to have reduced quality texture assets for sure so it can work in portable mode. Anyway I'm sure the developer understands that a huge part of the appeal of the game is the 60fps .
