For BOTW specifically you're better off playing on CEMU (Wii U emulator) as it's the exact same game(not a more limited version as one would assume) but significantly faster. TOTK you'll need RyujinX.
Exact numbers are hard to give: native game resolution or native macbook resolution? Docked or undocked? Shaders cached or not? Graphics mods (some of which are efficiency/performance related) or not? Generally though most games run at native size at native speeds once you get everything going. BOTW/TOTK are some of the heavier ones though and, ignoring BOTW as I play that on CEMU, TOTK runs alright as long as you don't push it or expect high FPS mods.
Dont know OP, but I am playing pokemon scarlet on it, m1 max macbook 15, and its pinned at 30fps.
Don't know if the game just wants to run at 30fps, or if my macbook can't go any faster. But since its stable at exactly 30, I assume it's the game
From my experience with yuzu and ryujinx, in order to exceed 30fps, most games need to be modded. Almost all popular games have a mod available though.
Most Switch games don't run at 60fps in docked mode because they can't nearly hit the framerate at 1080p. The Switch has dynamic resolution scaling but it still lags.
For this reason many games only run at 60fps in handheld mode.
