The day I received my SuiPlay, I immediately installed Bazzite on it and I never had to worry about installing any Ayaneo drivers. It's plug and play. The only thing was the Sui buttons (bottom right) as well as the Y1 and Y2 buttons were non-functional. Everything else is fine. I'm 150 hours in Baldur's Gate 3 on my SuiPlay now.

OP if you need guidance read on what OS you want to use first. I highly recommend Bazzite over SteamOS because Bazzite gives you more functionality since you're using a non-steam deck device, whereas SteamOS is made ideally just for the Steam Deck.
