GreemDev’s fork of Ryujinx is pretty good. My R5 5700/RX7600 is able to perfectly emulate SV at 36 fps*. It also runs okay on the Ally X. It mostly keeps a 30 fps but stutters hard when showing new animations, like when using a move for the first time.

As for the older Switch titles, I’ve only played Legends Arceus and it runs great on the Ally X. I also tried it on my Ryzen 5 4500U laptop and it runs pretty well over there too, so Let’s Go, SM and SS probably run great as well. 3

* Why 36 fps? Because the animations in the game are slow as fuck and tied to the framerate so disabling VSYNC and capping it at 36 fps with RTSS makes it run 20% faster, which is honestly a much better experience.
