Age of Empires IV just got a fresh 2024 patch and excitingly, it gets an official fix for Steam Deck / Desktop Linux multiplayer problems.
This has been a long-standing issue. Single-player was fine, but when trying online play the game would desync at some point. So unless you went through some manual fixing (which didn't work for everyone), it just wasn't playable online for Steam Deck / Desktop Linux players with Proton.
In the patch notes for the update released January 30th it notes clearly "Fixed an issue causing desyncs on Steam Decks when playing online." amongst fixes and improvements across various other areas of the game. Nice to see more Xbox Game Studios published titles getting improvements for us. What a time to be alive.
