Proton Experimental fixes controls in Starfield and supports Assassin's Creed Mirage

Valve has released a fresh Proton Experimental release for November 15th so here's your run over what's new and improved.

Noted as newly playable are:

• Assassin's Creed Mirage.
• Tenioha! feat. Mami.
• Killsquad.

Interesting that Valve notes Assassin's Creed Mirage as now playable, since it's not currently available on Steam. That hasn't stopped gamers though of course. People have been playing it on Steam Deck and desktop Linux with other methods like Heroic Games Launcher and NonSteamLaunchers.

Bug fixes:

• Fixed swapped start / select buttons on controllers in Starfield and other games using Windows.Gaming.Input.
• Fixed triple monitor handling in Project Cars 3 and Project Cars 2.
• Fixed load / save dialogs not working in Idle Spiral on Steam Deck.
• Proton 8 regression fix: games should be able to switch monitors in fullscreen mode on Cinnamon DE again.

Changelog can be seen here.

It will just show up in your Steam Downloads as an update for Proton Experimental, as Proton updates just like games do, so keep an eye out for it. Want more info about Steam Play and Proton? Check out my beginner's guide.
