Valve released a really small update to Proton Experimental on October 13th, so here's what's new and how to use it. This is the special version of the Proton compatibility layer for running Windows games, with lots of extra special fixes that eventually make their way into the main Proton version that's most used.

From the October 13th Update:

  • Fix Halo Infinite crashing without internet.
  • Fix Marvel's Spider-Man Remastered displaying dialog about outdated drivers on AMD systems.

Changelog available here. As a reminder, you now need Mesa 22 / Nvidia drivers 510.47 or newer for Proton Experimental.

Need to know how to change the Proton version used? See the below video:

I was finally able to play Halo infinite with the mesa-git flatpak add-on (need both 32 and 64 bit versions).

It runs well, but stutters occasionally. I disabled the shader cache, as I may have more than 3TB of installed games, but I wasn't actually booted into my main gaming partition (I had a computer fail and all that).

I was planning to try and run games through NFS on the Steam Deck; I hope they'll add the ability to enable the shader cache on a game-by-game basis.

For the readership whom are more prone to skimming, this should be bold (IMHO);

"As a reminder, you now need Mesa 22 / Nvidia drivers 510.47 or newer for Proton Experimental."
