As others have said, it’ll work on Linux. Right click on the game in your library, go to Properties, then Compatibility. Tick the box to Force use of Steam Play, then pick a Proton version, like Proton Experimental. This will work for most games. Check out the Proton DB website to check for any exceptions or specific settings. (You’ve bought a Steam licence for the game, rather than a version for a particular platform.)

Thanks, will give that a good read!

Thanks. If I access the client from another device, it’ll still just stream to that device though, won’t it? The same as using the Jellyfin web gui. I tried the Jellyfin-vue client, and that’s what it did.

I’m trying to keep everything in containers, but I could install something bare-metal (Linux), as long as I can access it on the home network (or have Jellyfin cast to it).
