Another update to Steam Play Proton has been released this evening, which should bring with it plenty of improvements for playing Windows games on Linux.
Looking to get started with Steam Play on Linux? Be sure to check our previous beginners guide.
Proton 4.11-8 now includes vkd3d, another library built on top of Vulkan to add in Direct3D 12 support. Other parts of Proton also saw version bumps like DXVK to 1.4.4, D9VK to 0.30, FAudio to 19.11 and Wine-mono to 4.9.4.
Don't know what any of that means? They're all the projects that work inside Proton to make it do what it does, they're all fresh versions meaning you should see wider support for games and probably performance improvements in places.
On top of that, they've tweaked the way Proton is distributed to use less disk space and be a smaller download size for future updates. Wine and other libraries had debug symbols stripped, however Proton itself is technically a Tool installed into Steam so now you can just select the "debug" beta on whatever Proton version to get them back. Do so like you would select a beta for a game, right click on it and go to Properties and then the beta tab.
For actual game support there's improvements for Rockstar Launcher and Grand Theft Auto 5, better gamepad support for Farming Simulator 19 and Resident Evil 2 and mouse input in Arma 3 is fixed apparently. The last noted game is DmC: Devil May Cry, which should now be playable.
Finally, their build system had a bit of an upgrade to allow easier redistribution of Proton builds between users which sounds fun.
As always, see the full changelog here.
On top of that, a recent update to the Steam Beta client also added back in the ability to actually see if a game is running with Steam Play. When on the page for a game, click the little I for the extra information and it's there, like this:
