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 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.

one guy with nvidia has the same problem on protondb https://www.protondb.com/app/378540
so its no just mesa

That's from very old reports when it did indeed not work in DXVK. That has been fixed for a while though (IIRC in 0.94).

Please try either stable mesa or amdvlk, the game is supposed to work and Lords of the Fallen (same engine) works fine on my end with the workaround. If you think this is a DXVK regression then please find the latest version that works, I can't provide any help unless I get some useful info.

Quoting: GuestNo Elite Dangerous yet through Proton, unless I am missing something.

Maybe you are, ED has been playable on Proton for some months now.
But you have to use a modified proton version:

Follow the instructions very carefully, or it will not run.

Anyone managed to get Uplay working with Child of Light? Mine just goes into a zombie process and Uplay does not actually launch.

I dread updating Proton because I'm afraid that it will make me download DoS II again. I have a backup, but it takes a lot of time to extract... can always start the process and walk away I guess. Just annoying. We'll see!

Strange, I thought it was possible to install .Net 3.5 with Wine 4.X.
But it still does not install with proton 4.2 with this game:
Batman Arkham City GOTA

Valve's Linux investments is the reason I mainly rely on Steam for my games, regardless of what other stores could offer.

Time to test my Steam play games against new version of Proton :-)

Somewhat OT:

I did play Doom 2016 for several hours but with one of the recent Proton Updates it stopped working. "Stopped" means it says "Preparing to launch" and within a second it's back to syncing. A steam steam://rungameid/379720 doesn't produce any error messages, neither does changing the Proton version result in a more successful outcome.
