Elden Ring runs really well in Linux – none of the microstutter that it still sometimes has in Windows.

The rest of the Dark Souls games run great too.

All of the King’s Field games run great in their respective emulators.

Lunacid is a great King’s Field _clone inspired game that just came out of early access and runs very nicely.

Dread Delusion is still in early access, but runs great and has a lot of stuff to do already. It’s like a Morrowind-ish experience.

Divinity Original Sin 2 works, but honestly, those games beg for a mouse and keyboard so the Deck is not my favorite way to play.

Edit: Shouldn’t call Lunacid a clone, it very much has its own personality.
