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.

Quoting: coesetaPlayed some Witcher 3 GotY yesterday, it just works out of the box for me. Runs @60FPS stable on Ultra settings without nvidia hairworks. Proton seems to be really nice :)

It already works like a charm w/ Vanilla Wine/devel from GOG so it is no surprise.

However proton games should all run in windowed mode otherwise they do not survive to alt-tab.

Some are ok running full screen & survive alt-tabbing back & forth.

The only problem is that the game requires stream output to be added to vulkan and implemented on dxvk or you want able to see some monsters that need it. This is why they don't add it to the white list.

Dungeon Siege 1+2 are both affected by the cursor drifting bug, hopefully this new Proton should fix them as well, I'll get them installed & see what happens.

oh wait I just remembered Dungeon Siege 2 has a black square for a cursor, fingers crossed anyway.

Well there no more drifting cursor at least, that's good news, I just have to remember how to change to custom resolution so I can play through the first game again.

Quoting: Comandante ÑoñardoAnyone know to disable the proton logs. They are eating more than 500MB of my almost full SSD.

Hi, can you tell me where the logs are located?

If they don't survive alt tab, report to Valve.

It has already been reported many times. I got the issue with every game I tried including Doom. Not a big deal as I prefer playing in windowed mode.

Anyway some games are affected by the issue with true MS Windows.

Quoting: Saulsecsiramirez Guess you can say this is picking up steam. ?

I think we can safely say that. After just a week there are already 771 issues created and 26 pull requests. You can't easily find projects with this much activity so early.

This is not exactly true since the majority are whitelist requests.

Of the 799 issues open currently only 304 are whitelist requests, but in any case, activity is activity.

Fullscreen not working is/could be a big deal for many if not most. For me it would be a deal breaker. Hopefully any issues with fullscreen will fe fixed soon.
