Valve and CodeWeavers are doing some great work for Linux gaming, with Steam Play seeing two updates in a single day.

Firstly, the older Proton series got updated to 3.16-9 which includes mostly minor changes like an updated DXVK to 1.0.2, a fix for some games failing or crashing in certain locales and fixes to minor xaudio2 and winhttp bugs.

Onto the real goodies now, as Proton 4.2-3 is also available today with some major changes included!

The first one is the inclusion of wine-mono, which they said should enable "many XNA games, Unreal Engine 3 games, game launchers, and more" to work. That's pretty big by itself, so it will be very interesting to see just how many more games become playable with Steam Play thanks to this.

Additionally, some noted titles that are now playable with this release on Linux are NARUTO SHIPPUDEN: Ultimate Ninja STORM 4, Evochron Mercenary, the launcher and update for Warframe is now "functional", Age of Empires II HD has fixed text input and something about "Continue maintaining Uplay functionality" which sounds good too.

Proton 4.2-3 also includes an updated DXVK to 1.0.3 and FAudio updated to 19.04-13-ge8c0855.

On top of that, while it's not clearly noted in the changelogs, Ethan Lee (creator of FNA, FAudio, Steam Play development, tons of Linux ports) mentioned in the FNA Discord (can be seen on Twitter in an image too) that Proton 4.2-3 actually uses FNA as the XNA 4.0 implementation. In their own words "This means that all Windows-only XNA games on Steam now use FNA's Windows support when run on Steam for Linux. It essentially puts the tools we've been using to hackport XNA games and drops them into the hands of every single user on Steam. When it comes to increasing the catalog size and user base, this is pretty hard to top!"

Very exciting stuff, I imagine there's going to be lots of Linux gamers excitedly testing plenty of games this weekend.

As always, you can see the changelog here.

Quotesomething about "Continue maintaining Uplay functionality" which sounds good too.

in the light of the recent news about google sabotaging firefox
(that's what software companies do as a standard practice)

Maintaining Uplay functionality is something that I applaud, I tip my hat to the devs.

This! This right here! This is why I love Valve and won't shop anywhere else, this is how you support Linux! (Take Note 'Epic' Games!).

Thanks Valve.

Gah, so many games to redownload and retest, ProtonDB reports to write, thank goodness I have a 4 day Easter weekend off work!

I am waiting for a fix to a regression regarding force feedback on Project Cars 2. Are there any specific keywords I should be looking for in future Proton releases?
Werner 19 April 2019 at 5:30 am UTC
this is not a regression of proton, it is a regression made by Project Cars 2, it works if you use a older version of PC2 which i agree is not a great solution.
But in my eyes best is to monitor this report, if something changes i think you will see it first there.

and for sure also the github report

Thanks for sharing, I am already following that discussion and running the outdated version so I can get some FFB (it's pretty weak, but I've read this is a characteristic of the game itself).

Anyway, if the problem is on the game dev side, should we ever expect it to be fixed? I mean, with Slightly Mad Studios even planning their own console, I imagine fixing bugs in an unsupported OS is the last thing in their mind.
Werner 19 April 2019 at 6:18 am UTC
I also think that they won't fix it at all on a unsupported OS, i think when then wine will need to fix it, i think currently no one knows whats causing the issue at all. Sad but our only option is to use the older version

Did someone try Space Engineers? Still "borked"?

CimerydI'm not sure when this happened, but Rocksmith 2014 has been a game I've always struggled to get to work with Proton. It worked alright if I just installed Windows Steam with Wine, but Linux Steam and Proton just couldn't launch it for some reason. Today, it works. Some time during the past month, something happened to make this game work, be that Nvidia's drivers, DXVK, Proton or a game update. This is wonderful!

Does the Realtone cable work now? If so, brilliant.

Debianeeryay! i wonder if Elite: Dangerous works now. >_> let the testing begin!

Man, Elite has been working for some months now.

I think people mean "is it working straight from the box", not requiring extra hacks to get going. Yes, I know this is Linux, but sometimes time is a factor .

I've almost got it running with Proton. Try it the days again and report. There is still a small problem with the server login. But I hope I have already found a solution. Just got to try it out.

Which would be more than great if you could run ED under Linux on Valve's new VR headset. This is my dream. Okay, not my only one, but one dream.

Strange, L.A.Noire works for Wine 3.14-->4.5, but not with Proton, even with Proton last version 4.2-3.
