Valve launched a new update for Proton Experimental for January 16th to improve various games and launchers working on SteamOS / Linux. There's also still Proton 10.0-4 with a release candidate that needs testing.

The main changes are:

  • Fixed Judgment freezing during tailing missions on most setups.
  • Made more games using MonoGame playable.
  • Updated Wine Mono to 10.4.1.
  • Improved VR support so that No Man's Sky VR mode is playable again.
  • Fixed VR controller tracking in Microsoft Flight Simulator.
  • Improved rendering of Rockstar Launcher popups.

How to get Proton Experimental? The new update will show up in your Steam Downloads for Proton Experimental if you have it installed already. Otherwise, it will automatically download if you go to play a game that Valve has set for Proton Experimental by default. Or, you can manually search for Proton Experimental in your Steam Library to install it and try it on some games. See all the details on the different Proton versions in the GamingOnLinux Guide.

Wow. Proton/WINE changes for a launcher. What did they do to make a launcher that complicated?
