The recent news that SteamOS may soon be shipped with third-party devices could be particularly important for Linux gaming on desktops.
Even gamers nexus' Steve today said that they're about to start doing Linux games performance testing soon. It's happening, y'all, the year of the Linux desktop is upon us. ᕕ(ᐛ)ᕗ
Edit: just wanted to clarify that Steve from GN didn't precisely say they're starting to test soon, he said they will start WHEN the steam OS releases and is adopted. Sorry about that.
Are you trying to imply having an "official SteamOS" means you will be able to call Valve to have them troubleshoot your game? Because you can't do that with the current official SteamOS on the Steam Deck. I don't think you thought this through.
