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

Just make the log directory not writable.

Heh. After me saying just this afternoon that Risen works perfectly apart from not saving, it now doesn't start at all.

Still, it doesn't seem to have broken anything else, although I haven't had time to properly test it all yet.

Try to find the configuration file and reset the refreshrate to 60. Helped the last time i updated my wine version for risen.

Had some pretty bad stuttering with my entire library before, this release really seems to have helped with that quite a bit.
I've went and replaced the wine binary links in /usr/bin/ to point toward the wine binaries included in steam's proton. It just seems to have better game compatibility and better fullscreen support than vanilla wine at the moment, at least for my system.

Here is the link for compatibility issues. Lots of games work. You can change the setting in steam play to allow you to install, play and test any windows game. Not all work obviously. I got shadow warrior 2 and astroneer working great so far.
