Get ready for another weekend full of testing games, as Valve and CodeWeavers have put out a fresh official build of Steam Play Proton for your pleasure.

Here's the highlights:

  • Improve behavior of PlayStation 4 controllers and controllers connected by Bluetooth.
  • More improvements to mouse capture and window focus loss behavior.
  • Farming Simulator 19 is now playable.
  • Fix some graphics issues in A Hat in Time and Ultimate Marvel vs Capcom 3.
  • Update DXVK to v1.3.4
  • Update D9VK to 0.21-rc-p.
  • Update FAudio to 19.09.

As always, find the full changelog here.

Great to see another release, every update should bring it that step further towards supporting more and more games whose developers or publishers don't wish to support Linux officially.

Something also related, Jason Evangelho who writes for Forbes and runs the Linux For Everyone Podcast (which I'm a guest on sometimes) just finished recording an episode speaking to CodeWeavers. Keep an eye on their Twitter or website for the episode going up in a few days, should be an interesting one.

What will you be testing with Steam Play this weekend? Let us know in the comments.

Will be testing Resident Evil 4 and Remnant: From the Ashes this weekend.

Newer Unity titles still don't render unfortunately (Telling Lies, A Place for the Unwilling, Dry Drowning).

two games on my bucket list I'd like to work better (apart from EAC/Battleye stuff),

Gothic3-FGEE and Space Engineers, both of these games have 'significant' issues relating to performance.

Might do a couple APITRACE in windows10 for them and upload that, might help somewhere down the line.

Reckon I'll give Fallout 4 another shot to see if they've improved the mouse capture in that game.
TheRiddick Sep 14, 2019
Allot of the mouse capture issues are related to people with more then 1 monitor, which apparently is not many of us. This results in the problem being prevalent apparently since testing is mostly done on single monitor setups.

Just discovered that Masters of Anima (which currently costs only 5€) works perfectly. I'll test it a bit more, then do a report on the Proton github.

Then I'll test Gothic 3 with the fresh D9VK: last version didn't work at all and with WineD3D performance was bad.

Also I started playing the old adventure Gray Matter, which also works like a native game: that is impressive because, if I recall correctly, it needed some tricks under regular Wine.

Quoting: TheRiddickAllot of the mouse capture issues are related to people with more then 1 monitor, which apparently is not many of us. This results in the problem being prevalent apparently since testing is mostly done on single monitor setups.

Yep, all of my mouse issues are when my pointer would leave the right edge of my primary game screen and appear on the left edge of my non-game screen.

For Fallout 4, I can work around the problem slightly by repositioning the virtual layout of my monitors to be above/below each other. It doesn't actually fix the issue, but you're much less likely to look directly up while playing! When you do, you'll still get the freeze as the mouse 'leaves' the game space, but it's much easier to deal with.

[EDIT: Well, this proton has no effect on Fallout 4's mouse capture - I still freeze when my mouse leaves the main window. BUT, see my edited comment below for a pretty sweet workaround. Obviously, it would be better if Wine/Proton actually handled multi-monitor better though.]

Couldn't you just disable one of the monitors before you start the game?

I'm still trying to get in-game sound working in Watch Dogs. All suggestions on protondb don't seem to help, so I'll try it with this Proton update and see...

Would mean moving all my windows back over when I'm done... not sure if that's more of a hassle to be honest! I'll do some tests this weekend though and report back.
