Yeah. Even though it's a switch, it's overclocked. I'd think dolphin will run a little slower.*a MASSIVELY overclocked Switch with about double the headroom to bruteforce Dolphin into working.
Point still stands. Compared to x86, it's a straight port without much platform-specific optimization.

Hardware-wise at least.Regardless, Shield != Switch. Different software and different APIs.

The footage you most likely saw was a Linux build of Dolphin running on a Switch booted into Arch Linux. Getting Dolphin to run through the homebrew launcher will take a lot more time and effort due to libraries and other specifics not written yet. The scene will have to mature a bit more before something like that comes around.
