Played through the entirety of Shenmue 1 on a FireTV2 which has about 70% of (throttled) Tegra X1 performance (= Switch Equivalent), and thats without Vulkan.
In "true" 16:9 mode.
(Only issue was a flicker on the main Characters eyelids in some sequences. Wasnt even that distracting...)
So yes - great times ahead.
Also N64 games, with 16:9 full screen hacks (can be implemented in the form of "cheat codes") and 720p+ internal resolution.
