Valve, CodeWeavers and the community have continued updating Steam Play's Proton and now the beta version of Proton has another new build out.

Don't know what Steam Play is? See Valve's official announcement. In short: It will allow you to play some Windows games on Linux through the Steam client as if they were any other Linux game.

To avoid some confusion: The Steam Play system as a whole is still in Beta, Proton (Valve's Wine fork) which Steam Play uses has a "3.7-3" version which is the default, but you can also switch to the Beta version of Proton itself in Steam's settings (compatibility tool dropdown box) to get Proton "3.7-5" which was just released today.

Here's the highlights of what's new in 3.7-5:

  • Performance improvements for timing APIs in CPU-limited scenarios
  • Automatically capture mouse in fullscreen windows is enabled by default.
  • More display ratios have smaller resolutions available.
  • Fix a crash on old versions of SDL.
  • Fix for mouse cursor drifting in Deus Ex.
  • Debug script dump directory can be configured with "PROTON_DEBUG_DIR".
  • Further improvements to fullscreen focus and python3 compatibility.

See the changelog here.

Honestly, it's really fun to watch this progress. There's been such a huge amount of excitement in the entire PC industry over this, it's crazy. It's going to be a while before we see what kind of impact it has, but this does give it time to mature for any scenario.

If you're after help with it, you can join our Discord Server which has a dedicated "proton-gaming" channel. We also have an IRC channel which is #gamingonlinux on freenode. Other social links can be found in our website footer.

As a reminder, Valve did state to report issues with games running in Proton to them and not to the developer of the game.

For me Doom 2016 (with Vulkan) doesn't work anymore with 3.7-5, it starts and I hear the sounds but the screen is black...

Quoting: legluondunetI'm waiting for a Proton version with:
--> DXVK directx10
--> Faudio integration: https://github.com/FNA-XNA/FNA/issues/90#issuecomment-415503383
--> windows media player replacement for video and music in games in MS format.

Gstreamer must be solve this issues (wmv and possible others) according andrew eikum

Also add fix for .net issues (mono modified?)

Quoting: MVinhasThree weeks ago I was worried about the future of Linux gaming, right after the Football Manager 2019 annoucement, and then this happened.

With all the pace on this developments, I start to believe that Football Manager 2019 will run even better than Football Manager 2018 on Linux!

One of my first thoughts (after just staring at the screen for minutes) was: Hahaa Football Manager is back on the plate. :)

Quoting: WoodlandorOddly enough, for me, Doom works perfectly with the OpenGl 4.5 renderer.
With the Vulkan renderer, the lighting doesn't seem to work.
Haven't quite figured that one out yet.

Since you're using a GTX 760, which driver version are you running? It shouldn't matter much since the game is already a couple years old and Vulkan didn't have as many extensions back then but you never know, it's the first place I'd start.

I think you meant to say IRC channel which is #gamingonlinux on Freenode network. IRC is not a place.

You at least need 396.51 for Proton , better to have 396.54

Quoting: garpuFYI, if you're on a distro that still has Python 2, Steam Proton 3.7-5 seems to require Python 3. If games don't start and there's a message in console about it not being found, install it, and games should start again. Most distros have a version of python 3 that can be installed alongside python 2, if python 2 is the default.

Here's the issue: https://github.com/ValveSoftware/Proton/issues/1004
Looks like it was from this commit.

Yeah, would've been nice if they gave us a head's up on that one...
