What emulator and settings are you using for ToTK? I tried playing it on my beefy desktop, and it couldn’t get passed 40-50 frame in the beginning area, while standing still…
I downloaded Yuzu from flathub before Nintendo went after it, but continued to use it after.
I had to expand the swapfile on my Steam Deck to prevent it from frequently crashing, but I don’t really care about frame rate, so long as it’s playable. I’ve not been paying attention to my frame rate.
