Proton 5.13: A Massive Update

read dead redemption 2

We don’t typically cover every little details of Proton versions released out there, but Valve has just released 5.13 and it’s breaking ground in several ways to warrant some coverage.

You can find all details in the release post on Github, but to make it short, it enables the following games to run:

  • Red Dead Redemption 2
  • Horizon Zero Dawn
  • Metal Gear Solid 5: Ground Zeroes
  • Final Fantasy XV
  • Sea of Thieves
  • Star Wars: Battlefront II (2017)
  • Call of Duty: WWII
  • Call of Duty: Infinite Warfare
  • Call of Duty: Modern Warfare Remastered
  • Asssassin’s Creed: Rogue
  • Assassin’s Creed IV Black Flag
  • South Park: The Fractured But Whole
  • DiRT Rally 2
  • Age of Empires II: Definitive Edition
  • Age of Empires III
  • Dragon Quest Builders 2

and more…

Here is one video of Infinite Warfare running on this new Proton version:

Having key AAA titles work directly via the vanilla Proton is a nice bonus for anyone not interested in tinkering with Proton-GE.

More importantly, this Proton version provides some early support for video in games. As you probably know, numerous games in Proton typically work fine, gameplay wise, but cannot play videos as expected on Windows. This is often due to different codecs used under the hood, not supported by WINE on Linux:

Beginnings of real support for all types of video playback. Games that use older video libraries should start working with this build. We are working on improving support for newer video libraries.

Proton 5.13 introduces more improvements in hardware support, audio support and network code:

Improved support for systems with multiple monitors.

Improvements to audio playback in Halo 3, Beyond: Two Souls and Tomb Raider 2.

Improvements to rFactor 2 multiplayer and Call of Duty: Advanced Warfare multiplayer.

This new Proton version also seems to be built against the latest containerization or the Steam Linux runtime. We are talking about containers at the application (=game) level, for better isolation and more portability across distributions. How this is currently used in Steam is not clear to me at this stage.

Finally, this is the first new Proton version in months, 5.0.9 being out in June 2020. I know some folks were wondering why it took so long for Valve to release a new build… well, I guess we now know why: it was a big update in the making.

If you try any of the games mentioned above, let us know how they run for you!

I struggle to run Battlefront 2 on older version of proton and any version of proton GE, but it is perfectly run with 5.13, thanks to Valve, Codeweaver and Wine developers


Now Assassin’s Creed Odyssey works out of the box, but not all games works with this new version. Still had to reinstall whole game, to make this work, because just switching to new proton version, deleted some game files. Conan Exiles not work, while with previous version it does. But that is not surprise – many issues are reported about this version, and that games not work with it for some reasons. Should be careful, using this version for now.


I tried out the new Proton last night with Monster Train (as reviewed here!) and took a long while for it to start up, probably due to the Vulkan shaders recompiling, though I did have to try twice for it to work. As a side note Steam doesn’t like when I try to switch the global Proton version in settings, often requiring a few restarts to accept the change.

Anyway, Monster Train still works great, but opening video still doesn’t show. So perhaps it is not one of those using an older codec (makes sense, new game).
