I'm not really sure how the upsides of immutable distros work. I've been using linux for a long time and I'm not an expert but I've learned bits of things here and there.

I recently bought a steamdeck and it's running an immutable distro. I don't really know how to use software that's installed via flatpak because it's weird.

I have a game installed that runs badly (unplayable for me) through proton. I can launch it through q4wine if I switch the steamdeck into "desktop mode" and it runs much better.

If it wasn't an immutable distro I could pretty easily make a shell script that launches the game through wine. Then I could add that shell script as a non steam game and it would (I think) run well, and I'd be able to launch it from the non desktop side of steam OS that is a lot more streamlined.

There is something comforting to me about immutable distros though.

I feel like I don't remember half the shit I have installed on my computers. If I wanted to start cutting things out I don't know where I'd start. But with flatpaks I get the sense I could probably just wipe anything I don't use out of the flatpak directory and I probably wouldn't break anything.

The first thing that jumped to my mind was Half Life 2. The facial expressions on the characters, and the physics of objects in the game world.
