Valve officially confirm a new version of 'Steam Play' which includes a modified version of Wine

As we speculated previously, Valve have now officially announced their new version of 'Steam Play' for Linux gaming using a modified distribution of Wine called Proton, which is available on GitHub.

What does it do? In short: it allows you to play Windows games on Linux, directly through the Steam client as if they were a Linux game.

What many people suspected turned out to be true, DXVK development was actually funded by Valve. They actually employed the DXVK developer since February 2018. On top of that, they also helped to fund: vkd3d (Direct3D 12 implementation based on Vulkan), OpenVR and Steamworks native API bridges, wined3d performance and functionality fixes for Direct3D 9 and Direct3D 11 and more.

The amount of work that has gone into this—it's ridiculous.

Here's what they say it improves:

  • 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.

It currently has a limited set of games that are supported, but even so it's quite an impressive list that they're putting out there. Which includes DOOM, FINAL FANTASY VI, Into The Breach, NieR: Automata, S.T.A.L.K.E.R.: Shadow of Chernobyl, Star Wars: Battlefront 2 and more. They will enable many more titles as progress on it all continues.

To be clear, this is available right now. To get it, you need to be in the Steam Client Beta.

There will be drawbacks, like possible performance issues and games that rely on some DRM might likely never be supported, but even so the amount of possibilities this opens up has literally split my head open with Thor's mighty hammer.

Read more here.

Holy shit. Please excuse the language, but honestly, I'm physically shaking right now I don't quite know how to process this.

Update #1: I spoke to Valve earlier, about how buying Windows games to play with this system counts, they said this:

Hey Liam, the normal algorithm is in effect, so if at the end of the two weeks you have more playtime on Linux, it'll be a Linux sale. Proton counts as Linux.

I'm liking this. There appears to be a common problem with sound. I can't get all the sound on mass effect 1 other than the intro swoosh sounds. Skyrim works lovely other than the standard freeze on quit which we are used too. No mans sky works great. Interestingly when I switch to 4k resolution on Ubuntu then run it I get a black screen with sound. Anyone getting sound but no video try out 1080p. Exciting. I deleted the wine install. If it keeps working well the windows partition is on borrowed time.
Kosh? Is that you?
Aren't you going to say "...and so it begins"? :)

Linux only has to be the second biggest and we still get the AAA titles, the creative suites, Fusion360, etc. We'll be large enough to be catered to like the Apple cult. That's all we need.
I wonder about that. Perception is a hell of a drug. Even if Linux earns more share than Mac on the desktop, I wouldn't be surprised if it remains marginalized for a good while because it's free and liberating (vs Apple's high-paying consumers who are used to being restricted and led by a leash) and associated with nerds (vs Apple's image of luxury and style). I'm not saying we won't get there, mind you, but I'm not at all certain that being the second largest userbase will cut it on its own.

Looks likes this is happening a bunch of people have been requesting a Linux port of City of Brass; the developer finally replied with a link to the announcement of Steam Play.
On the other hand, that doesn't have to be the end of the conversation. People can try it on Proton, find out what doesn't work, and report back to the dev. Knowing that they only need to fix a few issues that can't be handled by a default compatibility layer and seeing first-hand how many users are trying to play their game, what's to say the dev won't cave in and finally put some time into making their game more compatible with Linux, even if they don't truly port it? If they do, not only is it good news for their existing players who run Linux, but it puts the OS on their mind for future releases. Even if they won't port, they might consider choices that make their games more compatible with Steam Play, such as Vulkan. The snowball effect could be interesting.

This is an opportunity for Linux gamers to advocate the platform and work hand in hand with devs.

I have to confirm, that running some of the games on 4K is problematic...
...that is why it feels like I'm almost the only guy on the planet, for whom Doom is not working out of the box... (and yes, before you ask - I have a pretty standard config of Ubuntu 18.04 with GTX 1060 on 396.51). But after several tries/fights I won and I can shoot the whole Mars hell into oblivion.
Crysis is also reported to run ok, but on my 4K it is again a nogo..

Reading Lin_Soldar's comment made me realize that I might be able to play games that I got in my humble monthly bundles... Games that I never claimed because they are Windows only... I guess I will have to update my humble inventory. :)

I managed to break Proton earlier, after a "quick" reinstall of Proton I can get back to testing games.

Borderlands, works perfectly
All the original Doom games up to Doom3 ROE working perfectly with the usual cfg tweaks for screen resolution
Torchlight, works but crashes if you try to delete save games.
Unreal Gold, working perfectly.

There is actually a linux native version of Torchlight. However, it is only available through Humble Store. (I have it from an old bundle.)

I got that version from Humble Bundle, many moons ago too, best of both worlds. :D

ps I can now add Neighbours from Hell & Neighbours from Hell 2 to the list of working games.

I'm curious to see how this is gonna reflect on the Steam HW survey... So far Linux gamers playing on wine have always counted as windows. Now they're apparently properly counted as Linux. So maybe we see a spike there too.

just randomly installed a windows only game, that is not officially supported and it as just working fine: Professional Faermer 2014

Sadly I couldnt find another game in my lib, that worked, among the ones I tried:
- GTA 4
- Burnout Paradise
- Heroes 6 (ofc this thing is even download the crappy Upaly cielnt for it)

UPDATE:
hmm I have just checked again, and Burnout Paradise works flawlessly now :)

That is surprising, Burnout Paradise works pretty effortlessly in vanilla wine. Well, in staging at least.

Mmmm... Someone dusted off Carmack's 2013 declaration... I found that interresting, given the actual context:

Far Cry 2(buggy but started on with display options set LOW. Minecraftesque foliage. Technically playable, but no.)
Far Cry 3
Batman Arkham Asylum GOTY
RWBY: Grim Eclipse(installs, boots, runs, doesn't display character models in game making it unplayable)
Alan Wake
Bioshock Remasterd
Call of Juarez Gunslinger
Deadpool
Warhammer 40K Space Marine
GUN
Strider
Transformers: Devastation
Mafia II

Working:
F.E.A.R.
Max Payne 2: The Fall of Max Payne

Just to refresh the info:
THIS is the "live" version of the tracking document, and it has grown 1,5 times from yesterday (to roughly 2600 test entries as of this morning; so pretty impressive so far):

Thanks for the link, I added my first game to the list this morning (hasn't shown up yet though), FLOCK! works perfectly with no tinkering whatsoever.

This generated view [External Link] loads a lot faster and it's cleaner without the useless editor bits. It seems to update every 5 minutes so it's live enough.

Hum, since you didn't tell before I asked, have you reported your findings on Valve's Proton Github? DOOM is supposed to be supported :D

No, wine gamers are NOT going to be counted as Linux. However, Proton users obviously run the native client, so players that previously used wine to run steam, but now use the native Steam + SteamPlay ARE going to be counted as Linux :)

Hopefully someones builds a few libraries to easily use the native Steam API with regular wine/wine staging. I foresee this happening soon enough :)
