So, two years ago, we started an effort to improve the quality and performance of Windows compatibility solutions for Steam games. A lot of our work has been in the form of supporting Wine and other existing compatibility projects. We have also been integrating these tools into the Steam client to provide the same simple plug-and-play experience offered by regular Linux games.

Our goal for this work is to let Linux Steam users enjoy easy access to a larger back catalog. We think it will also allow future developers to easily leverage their work from other platforms to target Linux. This would give them the option of focusing on areas that would make a meaningful experience difference for all users instead, such as supporting Vulkan.

As a result of this work, today we are releasing the Beta of a new and improved version of Steam Play to all Linux users! It includes a modified distribution of Wine, called Proton, to provide compatibility with Windows game titles. Here are some of the improvements it brings to the table:

  • Windows games with no Linux version currently available can now be installed and run directly from the Linux Steam client, complete with native Steamworks and OpenVR support.
  • DirectX 11 and 12 implementations are now based on Vulkan, resulting in improved game compatibility and reduced performance impact.
  • Fullscreen support has been improved: fullscreen games will be seamlessly stretched to the desired display without interfering with the native monitor resolution or requiring the use of a virtual desktop.
  • Improved game controller support: games will automatically recognize all controllers supported by Steam. Expect more out-of-the-box controller compatibility than even the original version of the game.
  • Performance for multi-threaded games has been greatly improved compared to vanilla Wine.

Maybe this will be the thing we need to go full Linux. One thing to note is

Q: Are there any games that will never work with Proton?
It's likely that some games using complex DRM or anti-cheat systems will be difficult, or even impossible to support.

I'd have wagered Denuvo would be one of the problematic DRMs, but two of the games using it are on the list of whitelisted titles (NieR: Automata and Tekken 7), so maybe even that won't be an issue.

This is great news, Microsoft having a PC gaming monopoly is no good for anyone... Vavle's attempts at getting devs to do native Linux ports hasn't been all that successful either. Maybe this way they can grow a big enough player base on Linux to make native ports in the future a more viable proposition for devs.

Opted in for the beta client. 😊
Let's see how well will JC2 play.
Edit: They have only enabled this yet only for some selected titles. Seems like I have to wait some time :(

You can try it out also for unsupported titles, refer to FAQ in OP.

Tried but everything has gone bad than they were.
Also Borderlands 2 which I could run smoothly before has lots of frame drops now.

Valve finally did something good again. I am so happy end excited for this one as I was getting sick and tried of dealing with my very broken, borderline unusable Wine install of Steam.

Valve doing something really beneficial. And good.
Must be the time of year when our universe briefly collides with that of a mirror universe and some things seep through. Nowadays it is so uncharacteristic from them to do something this beneficial to the gaming community (even if this will improve business, technically, the Linux users can spend some more money). I wonder where this may go, despite them having almost marginally no Linux users among the userbase.

Valve pushing open source and fighting a good fight again. Nice to see that. I had to abandon Linux a few years ago because of my work, but am strongly supporting this initiative. Yes, native games would be much better, but you can't force all the devs/publishers to do it, so as a 2nd best thing, this is great.

FAQ is also a great read, and some of the suggestions can lead to good things in general:

Q: I'm a developer; I wasn't planning on targeting Linux, how can I best leverage the new Steam Play?

We recommend you target Vulkan natively in order to offer the best possible performance on all platforms, or at least offer it as an option if possible. It's also a good idea to avoid any invasive third-party DRM middleware, as they sometimes prevent compatibility features from working as intended.

And here I am. Played linux native games for last couple of years on my Dell XPS. Missed some Skyrim. Installed windows on the weekend and now I see this. Don't tell me Skyrim LE is available under linux via Steam Play.

PS: looks like Skyrim works: https://steamcommunity.com/app/221410/discussions/0/1734336452575505938/

This is great news!
Im still going to buy only games that work on Linux so this does not affect me very much. But it does helps linux gaming.

Found a thread where people share their findings of what works and what's not: https://steamcommunity.com/app/221410/discussions/0/1734336452575505938/
Skyrim, Oblivion, Elder Scrolls: Legends, Red Alert 3, The Walking Dead, Bioshock, KOTOR, Overcooked, DMC4, GTA San Andreas, No Man's Sky, and many more are working. I'm hyped! Cant wait for the stable release.

There is also a spreadsheet where it might be a tiny bit easier to find info about the exact game someone might be looking for.

Exciting news. There's a community list of games which work or not on google docs.

Souds great! Maybe I can finally use Linux only
(right now I have too many games that do not run on Linux, so that I have to use Windows to play them, unfortunately)

Looking forward to give it a try :)
