Valve have pushed out a Steam Play beta update with Proton 3.16-7 now available for testing. Lots of fixes!

Not quite the huge upgrade many were expecting, most people thought Valve would be pushing ahead with a major update of Wine but this release still seems like a very nice update overall

Firstly, they've updated DXVK to 0.96 and FAudio to 19.02. This should hopefully mean quite a number of games will see improvements and begin working. Additionally, there has been some controller improvements, with Unity specifically mentioned for games like Subnautica and INSIDE.

As for bug fixes and other changes, here's what they improved:

  • Fix for fullscreen behavior in Into The Breach.
  • Fix for crashes in some d3d9 games on Mesa.
  • Fix for crash when launching certain games, including Path of Exile, the Bloons series, and the Naruto Shippuden series.
  • Fix for games with special characters in paths, including LEGO Harry Potter.
  • Restore previous functionality of the Uplay client.
  • New runtime option for old games that can't handle modern GL extension strings. Set PROTON_OLD_GL_STRING to limit the extension string length.
  • New runtime option to disable d3d10 support, PROTON_NO_D3D10.
  • Better support for games that use very old steamworks SDKs, including Lost Planet.
  • Fixed various problems with the build system, and added a new top-level Makefile to make simple builds much easier.

You can see the changelog here. Looks like it's going to be a fun weekend of testing ahead!

If you're having issues updating, you can select Proton from Steam's tools menu found when you hover over "LIBRARY" -> "TOOLS" and search for "Proton" then install "Proton 3.16 Beta". Seems many people have had issues with it not updating properly.

After some fresh testing, with a forced Proton update I can confirm Into the Breach fullscreen now works as expected—hooray!

It's coming along very nicely,
They just need to address the anti-cheat app problem (ie. Empyrion) AND the explicit windows-services checks that some games unfortunately do but don't use (ie. Space Engineers), because wine don't fake those yet.

I wonder if the UPlay fixes will allow Watchdogs 2 to work!

Assassin's Creed II still can't install -- I mean, it gets stuck at the disk space allocation phase, before uplay can even do anything. Weird.

The problem with old Assassin's Creed games is that the Steam client can't load the cd key. More info on github isue isue. When Valve fixes this Assassin's Creed 2 will be working.

Looks like the setting only applies on non-whitelisted games though.
Whitelisted games seem to use whatever version Valve used when whitelisting it, which makes sense actually because it eliminates the potential for regressions.

Dark Souls II:SotFS - Proton 3.16-7 selected by you for all titles
Dark Souls III - Proton 3.16-4 selected by Valve testing
NieR: Automata - Proton 3.7-8 selected by Valve testing
You can manually force those games remember, which is what I did for Into the Breach and the Steam client clearly said I was on the new version.

What happens if you try to override the predefined version with a custom choice?

AC2 lutris script works i used it less than three days ago, there is are some graphics options that youll need to turn off in order to make it full screen but they are things like motion blue which makes me heave when its on anyway but you're mileage may vary.

Sure, but the key request has its own prompt, as well as a distinct error message when it fails. I don't even get that far, the installation dialog gets stuck as it's allocating disk space -- which is all the more strange, because the download does run in the background. When I close the installation window the downloaded bits are erased.

Does anyone else have the problem I do where Steam deletes all of your Proton games if you change Proton version in the main Steam settings? I have had to download Divinity: Original Sin 2 at least three times now, and it is a huge download! It's very aggravating. I have a local backup now, but I don't enjoy having a 50 GB game backup eating up disk space. It's also not any fun to restore that backup from one disk to another. It's faster than downloading but it's still a PITA.

Quoting: torbidoWhen I add non steam game, where is the prefix of these games?

Each version of Proton is a management wrapper for Steam-Installed games using a specific version of Wine ( including extension libraries/patches etc ).

As you probably know, each Steam-Installed game is identified by a unique integer number; Proton creates/uses a Wine prefix for each game as a directory named for that unique integer, in the "compatdata" directory of the Steam games library you choose to install in.

I do not think Proton is capable of doing this for non-Steam games, so a non-Steam game will use the wine prefix you chose when installing that game. If you make no wineprefix choice, the default is "~/.wine/".

Note that it is generally better to install each non-steam game to a different wine prefix, since games often have conflicting configuration needs. i.e. Configuring one game may break another if they share a wineprefix.

Hope that helps.
Actually, Steam does create a folder in your compatdata (~/.steam/steam/steamapps/compatdata/ or ~/.local/share/steam/steamapps/compatdata/) for non-steam games. The folder's name is a number. I don't know how that number is determined though.

Really? I've never tried adding non-steam games myself, as I assumed it just meant pointing at an existing game so you could launch it from the Steam interface. Sounds like it does a bit more than I thought.

Is that the amount of system RAM used or the amount GPU memory used?

I don't know for certain, but I would expect it to be the GPU allocation, since that is what DXVK is most interested in. CPU allocation is less important since the OS can provide virtual memory.

50 . . . gigs. For one game. I've had hard drives way smaller than that. I've had adventure games I plugged away at for hours and never finished that were 16K. OK, I didn't finish them mostly because they were badly designed, but still. What is the excuse for a game taking up 50 gigs?
Sorry, my old curmudgeon is showing, but really . . . 50. gigs.
