They Are Billions Proton Experimental

A new Proton Experimental update was pushed out yesterday with a few small changes. We now have all of the improvements from Proton 11's first beta and all of the components updated to their latest versions, including FEX for ARM. We also have a fix for They Are Billions, which suffered from low FPS during the intro cinematic.

The new Proton Experimental update should automatically download if you already have the experimental layer. If not, just search for Proton Experimental in the Steam store on your Steam Deck and download.

Proton Experimental 4/21/26 Update Changelog:

  • All changes from Proton 11.0-beta1.
  • Fixed Proton 11 regressions:
    • They Are Billions should no longer suffer from low FPS when playing the intro cinematic.
  • Updated vkd3d-proton, dxvk, vkd3d, dxvk-nvapi and FEX to the latest development versions.
