I've been trying out this project on my Ayn Odin 3 (Android based handheld with a Snapdragon 8 Elite) lately and I'm genuinely amazed.
It's crazy how the pipeline of FEX, Linux, Proton/Wine and SteamOS lets me play Windows games on a handheld ARM device that was supposed to only run Android.
It sometimes needs some tinkering (as with the SteamDeck), and you won't be able to run the latest games at highest graphics, but I was able to play quite a lot of good titles from my library, self-dumped roms through emulators and even the old Trackmania games from 2008 flawlessly.
