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: theghostMost important question:

Is the Skyrim SE sound bug (no NPC voice) finally fixed?
Use this one, and you will have all sounds. https://github.com/Kron4ek/FAudio-Builds
I do that in this video, and play a lot time with it, with no problem:

So it's not fixed yet.
Well thx for the info.
I will stick to the normal version of Skyrim.
As I don't want to tinker with extra hacks.

Quoting: GuestI downloaded nearly all versions.

Me too, but in the future this might be a problem with a lot of versions. Unless Valve start to remove old releases.

Quoting: GuestMy guess is it won't be that much of a problem because Valve will take care of the regressions and older versions will be less necessary. Eventually they will be able to phase them out as you suggest. But it would take an awful amount of work to QA all those games and if they restricted Proton to the game they whitelisted themselves there would be an uproar.
Welllll . . . I would expect there will always be a few regressions when a new version comes out; that seems to be the way of all software. So there will be a use for a couple versions back. But it's not totally unrealistic to hope there won't be really long-lasting regressions, so that there won't be any need for versions from years previous.

I took the risk of downloading AC Unity -- and uplay now works out of the box. The game ran almost perfectly at 'high' settings (picked up the ancient savegame from my windows playthrough just fine) until I tried -- after about 10 minutes -- to fast travel to a spot; at which point it crashed to the desktop.

The "Press space to continue" bug still present in PROTON 4.2-1
I remind you that this is a WINE issue and not a GAME issue...
I tested it on a Windows 7 machine and the bug is not present there.

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.
