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:

Quoting: legluondunet
Quoting: [email protected]Anyone managed to get Uplay working with Child of Light? Mine just goes into a zombie process and Uplay does not actually launch.

Uplay is now functionnal with Proton 4.2.
Delete the Child of Light proton game folder "compatdata/256290", launch the game and try disabling uPlay's game overlay in the general uPlay settings.

Really Uplay works now excellent can finally try splinter cell conviction again

Sniper Ghost Warrior 3 eats a bit more memory in this version of PROTON.

Tried Far Cry 3

Initially Uplay works ok but the game started with a black screen.

So I killed everything and tried again and in Uplay I disabled the "In game overlay", then the game played great.

The only glitch was exiting the game. "Exit to desktop" resulted in a game screen freeze / hang, needed to kill the game process and exit Uplay.

I will need to test this again.

140h at The Witcher 3 on Proton 3.16 beta without problems.
2h on Proton 4.2 and the game has been crashed twice - the picture froze and nothing could be done.

I have only "The Crew" from Ubisoft, Uplay and the Game worked correctly from Proton 3.16.8. I did not spend much time on Proton in this game, because I finished it on Wine-Stagin 3.21 + DXVK.

Currently I use Wine only for games from Orgin (My son likes the Need for Speed Series), I had a lot of problems with games on Wine versions up to 4.2, with 4.4 is ok, on the latest 3.xx games have been operating without problems. Orgin client starts without any errors on Wine 4.4.

I wonder what the problem with AC II and Brotherhood is -- I assumed that it was due to the uplay authentication bug, but though that seems to be fixed now, these two still don't properly install.

I like hopping on Venetian rooftops while listening to a podcast or an audiobook, and I haven't been able to do that for a long while now.

Uplay improvements are very impressive in this proton version



In my case farcry 3 run in both modes DX9 and DX11 (and many other uplay games )

Maybe you are, ED has been playable on Proton for some months now.
But you have to use a modified proton version:
https://github.com/redmcg/wine/releases/


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

This workarround is no longer needed with the new Steam Play/Proton version. If you have protontricks and winetricks ready you really only have to run
protontricks 359320 dotnet40 vcrun2015 win7
after the first start.

See also https://github.com/redmcg/wine/wiki#the-official-build-of-proton-42-runs-ed

Edit: Eventually you'll also need this: https://github.com/ValveSoftware/Proton/issues/150#issuecomment-453244721
