This is quite an exciting release for Steam Play, as Valve just put out a brand new release of Proton.

It moves the version of Wine used from 3.16 to 4.2 which includes a rather large set of improvements by itself, so it should have quite an interesting effect on what games are now playable. What's especially nice, is that Valve said 166 patches from Proton 3.16 "have been upstreamed or are no longer needed".

That wasn't all, DXVK also saw a version bump so it's now using 1.0.1 and FAudio too joined the party with it pulling in a newer build "19.03-13-gd07f69f".

There's a bunch of other improvements too like better mouse behaviour in certain games, with Resident Evil 2 and Devil May Cry 5 specifically mentioned. Networking fixes made it in for NBA 2K19 and NBA 2K18 as well.

Controller/Gamepad duplication in games that use SDL2 like RiME should also be fixed, which I am sure many will appreciate as decent gamepad support could be something to make or break Steam Play. Any small hassle that gets fixed, is welcome.

Proton's special fullscreen "hack" should also now work with "GDI-based games", there's better support for IVRInput for controller input in VR and more improvements and new features to the build system.

As always, you can find the changelog here.

Do note though, Valve developer Pierre-Loup Griffais said on Twitter that you will want to install it manually from Steam's "Tools" area. Griffais said "That process is supposed to be automated, but there is currently a bug with games that use another redistributable".

You can find that here, for those that don't know:

This, right here, is why I'm a Steam loyalist. GOG may be DRM free, but they sure are useless for Linux

Valve is there some way I can send you money without buying a game?? Because seriously **thankyou**.

Oh my god I got so many games to test now. I'm going to have to redo every one of my borked games to see what difference 4.2 makes. This is gonna be soooo guud.

Thankyou thankyou Valve!

This is why I absolutely refuse to even consider downloading a free game from EGS, screw Epic, they hate gamers in general and they hate us as well, they won't even port games made in a Linux compatible engine or port a store made in Electron. The sooner they go out of business the better off the entire world will be.

Cool.

Wow, awesome. Yes, I used an workaround for RIME, and is all good now, but having this working out of the box is so great.

awesome, finally we are at 4.x, now i really hope that finally some of my Racing Games are getting FFB support for my Wheel
Perfect!
Time to repeat failed experiments.
It seems Gaben is reacting.

Please don't oppose Steam AND Gog, they are two games sellers that support Linux, they all two deserve respect from Linux community.

Don't forget to test your games and do lots of ProtonDB reports to help the Proton and Wine devs, also report any regressions to Github for Proton!

Have You deleted the game data folder "378540" that is inside the "compatdata" folder?

Is the trial or the full version? Because the DEMO ID is 646690
People, I remind You that Killing Floor 2 can be played for FREE until April 1st and it works OUT OF THE BOX on PROTON...
So, don't miss the opportunity for to do your own protonic test.

Well you can add in any GOG game and run it via proton via the in steam shortcut system, it works for the most part but be warned it creates invalid game paths initially and you must go into the shortcut and select target again.

The main problem I have with GOG is that some games have disabled features because the developers want a authentication method to enable them (ie NMS multiplayer). So you get a inferior product on GOG with some titles, GOG need to add that feature into Galaxy quickly and also release it for Linux/Mac users.
TheRiddick 27 Mar 2019
It's possible for your proton versions to get corrupted, I had to PURGE proton entirely from my system and start again because steam was getting confused about installing it correctly and I had pre-existing broken proton files around the place.

Also proton doesn't like running directly from NTFS drives, you need to symlink compat data folder (as per wiki instructions).

This is a regression in mesa-git which affects Lords of the Fallen as well. I'm working on getting a useful test case for the driver folks to reproduce this, but it's a rather tricky issue.

As a temporary workaround you could build this DXVK branch, it was originally meant to solve a different problem but just happens to work around that driver issue as well.

Does this mean Resident Evil 2 now works without Windows Media Foundation hacks?

No, but Mouse+Keyboard are finally usable.

Just for anyone who is interested.

Finally managed to get Anno 2070 (steam version) working.

I had managed to finally pass product activation using proton 3.16.8 beta by using "PROTON_NO_D3D11=1 %command%" as the screen was black and was unable to enter key. Was still unable to launch the game.

Game now runs on proton 4.2 and the game downloaded all the patches and Uplay worked perfectly. Still need to disable the Uplay overlay or game will crash.

Still cannot run Anno 2205, Planetcoaster or JWE. These are the last on my non working/running list and would really like to see these working soon.


Big Thank you from me to all the teams involved for this great project.
