On Windows, the go-to emulators are Bluestacks and NoxPlayer (both closed source), especially when gaming is concerned. Unfortunately they are not available on Linux, and the Nox devs’ dismissive attitude towards Linux also makes it unlikely they’ll ever make a Linux port:
So apart from trying to run these two using Wine, what emulators are out there on Linux that yield a sufficiently decent performance to make Android games playable?
EDIT: looks like Waydroid is a winner, see the comments.
Re: Genshin: wouldn’t you have more luck (and better performance) playing the Windows version through WINE?
