DroidDeck looks great but at the moment only really seems good for Qualcomm devices. I tested a fork that is adding other GPU support on my Pixel Fold yesterday and got a few games to run but most did not. Balatro ran but was missing text, Half Life 1 worked pretty much fine, a lot of games did not boot at all. I am impressed at DroidDeck's desktop mode though, they have a Wayland KDE session and Flatpak running, something Termux doesn't seem to have working yet.

e I just ordered an Ayn Thor recently but I'm going to put proper Linux on it with ArmadaOS or something.

My OnePlus 7 is not fully compatible but I tested anyway. I was able to play a little bit of Slay the Spire but then the game crashed for some reason.

An alternative that works well for my device is GameNative. You can connect Steam, GOG, Epic Games, etc, and install games on your phone. Slay the Spire, being the example in this comment, works well in GameNative for me.

Has anyone compared it to gamenative?

Compatible Devices

I used it to play deltarune on my OnePlus 8T. Amazing! Steam deck everywhere!
