Here’s an installation guide for a launcher + a mod pack for the steam deck, I just installed this and messing around it seems to be 60 fps (not locked 60, but mostly 60 with some drops) even with shaders.

Update: for anyone else who’s stuck in the same situation, I think I figured it out? The issue was that my internet simply wasn’t downloading from GitHub, but changing my connection from metered (auto) to off fixed it? Not sure why, but I was messing around with a bunch of internet related settings and that’s what seemed to work.

Yep same, I just got mine a couple weeks ago. Well, it still works and plays the same games, so I’m not terribly sorry, but it does sting if I think about it too much 🙃
