Valve released a fresh build of Proton Experimental on January 13th which include a few notable improvements across various games for Steam Deck and Linux desktop.

Here's what's included:

  • Fix A Plague Tale: Innocence showing on-screen keyboard when starting the game on the Steam Deck.
  • Fix rendering issues during cutscenes in Tom Clancy's Splinter Cell.
  • Fix Japanese keyboard input in Final Fantasy XIV Online.
  • Fix Football manager 2023 crashing when trying to return from a player profile.
  • Fix experimental regression: Fall in Labyrinth started crashing on some setups.
  • Improve CJK characters rendering in many games including NOBUNAGA'S AMBITION: Souzou with Power Up Kit.

Changelog available here. As a reminder (for desktop), you need Mesa 22 / Nvidia drivers 510.47 or newer for Proton Experimental. Steam Deck is fine as Valve control what's needed for you.

Don't forget that Proton Next (7.0-6) is also currently in testing!

As usual a video running through it, with a guide on how to change the Proton version per-game and as a whole for the Steam Deck:

One thing I noticed that seems to be absent is the ability to install language packs. The lack of language packs tend to be a problem with trying to run old Windows Japanese games.
