The Proton compatibility layer used with Steam Play on Linux has a brand new release out with Proton 5.13-2. This release follows on from some Release Candidate builds earlier this week, to clean up some issues after the big initial Proton 5.13-1 release that went up in the middle of October.

Need more info on Steam Play and Proton? Check out our dedicated area for it.

Here's what's changed in the Proton 5.13-2 release:

  • Updated vkd3d-proton to version 2.0, which improves Direct3D 12 support.
  • Fixed Risk of Rain 2 multiplayer lobbies.
  • Fixed Killer Instinct crash when battle ends.
  • Fixed Assetto Corsa Competizione and Summer Funland in VR mode.
  • Fixed games not launching in Uplay Connect, and Origin crashing when updating.
  • Fixed mouse cursor in Mount & Blade II: Bannerlord.
  • Fixed SpellForce crash on launch on some systems.
  • Fixed very long load times in Warhammer 40k: Inquisitor - Martyr.
  • Atelier Ryza: Ever Darkness & the Secret Hideout is playable again.
  • Fixed Healer's Quest and Coloring Game 2 on AMD.
  • Scaled resolution now functional for Middle Earth: Shadow of War.
  • Restore behavior of horizontal scrolling input from previous Proton versions.
  • Proton log directory can now be configured with PROTON_LOG_DIR.

Full changelog can be seen here

While Valve, CodeWeavers and Collabora all work together through contracts to make things better there's still a number of known issues right now including:

  • Controller hot-plugging doesn't work
  • System-wide Vulkan layers like MangoHUD or vkBasalt don't work
  • Using a custom per-game driver (like with VK_ICD_FILENAMES or LIBGL_DRIVERS_PATH) doesn't work
  • User hooks like LD_PRELOAD (like for MangoHUD OpenGL) don't work

i hope resident evil 2 is fixed
Oh ... and I was wondering why MangoHUD suddenly stopped working. (Since 5.13 ?)
Tried the latest release, installed from source eg :D

Now I feel pretty dumb not reading release notes xD

Still I wonder why it does not work in lutris either 🤔 Is Wine 5.7 affected by this either?

Amazing. One regression is that it prevents death stranding from starting but the game was barely playable with 5.13-1

I'm really happy with the VR fixes for ACC. That game was a major factor in considering an Index.
Now lets hope that Nvidia or AMD do their homework for the new generations since I need a bit more GPU power :).
Hmm.

Anecdotal, but my current game of Doom 2016 just got less stable after they updated. The main game still plays OK but it hung during the update, then reset my graphics settings. After playing it crashed on exit.

Sometimes the achievement popups don't disappear, but that affected other versions of Proton, too.

While I am grumbling, does anyone else get the Steam Big Picture "bong" when pressing the face buttons on the Steam Controller, even in-game? (sometimes)

Still broken for me, games don’t launch at all with 5.13.

Problems with the Steam Runtime?

Where you did install your games? If in "/usr/" it won't work’s
