Huh, didn't really expect the actually cart to be the slowest of the bunch. But I guess it kind of makes sense when you think about it.
Does this also affect how Switch (1) games perform on the system? Like, if I have the game on a physical Switch (1) cartridge loading times will be capped by the actual cartridge? But if I have the same game digital the Switch 2 will be able to speed things up?
