Valve Proton

Valve introduced Proton to try and get thousands more Windows-only games playable on Linux without developer support. Two months on and it's clearly working as 2,663 games are already Linux.

• Valve Releases Proton 6.3 BY Ekianjo April 3, 2021 Leave a Comment We knew it was coming, and here it is: the latest Proton now rebased on top of WINE 6.3 (dating from end of February, so Proton is behind the dev branch by a month or so). Proton 6.3 should now show up on Steam for you all.
• Yet the Proton project on its own has already changed the face of PC gaming on Linux, and shows that Valve is committed to far more than simply pushing out iterative updates for Counter-Strike or figuring out an anti-cheat that doesn’t make honest players rip their hair out by the fistful.
• Valve has launched a beta for a new project in support of it’s Linux development. Starting today, Valve is officially developing and supporting a fork of the WINE compatibility layer called Proton, which will run in conjunction with Steam. Proton will allow games that have not seen an official Linux release to run on Linux through this compatibility layer.

With Cyberpunk 2077 being the hot new thing in gaming, Valve and CodeWeavers are trying to ensure it can run nicely through the Steam Play Proton compatibility layer since it doesn't support Linux directly.

Valve recently set up a new branch of Proton named 'Proton Experimental' along with the release of Proton 5.13-4. It appears to be the version of Proton where Valve will be adding in fixes quicker, and more newer features. Yesterday, December 14, Valve developer Pierre-Loup Griffais mentioned the newest updates to Proton Experimental implements the Spatial Audio sound API which should fix Cyberpunk 2077 world sounds. Additionally there's more CPU performance improvements, which should help Path of Exile too.

Currently though, NVIDIA still has issues with it crashing and sometimes entirely locking systems on Linux. I tried it myself today thanks to a gift from a reader and the experience for me on an NVIDIA 1080 wasn't great. Ensuring to set my CPU into performance mode with High game settings it gave 30FPS and below, Medium gave a total freeze on the loading screen but a good 10FPS increase to between 30-40FPS in game when it does work (a little higher in more confined spaces).

Safe to say, you need a really high-powered computer for it right now, especially on Linux and not NVIDIA. That will change over time of course as CDPR optimize the game, as Valve optimise Proton and when NVIDIA sort the driver situation out. Even so, incredible it was working so soon with Proton on Linux.

Here's all the current additions in Proton Experimental:

Proton Db

• Beginnings of Wine architectural work to reduce CPU overhead and improve performance in scenarios related to input and windowing.
• Memory allocator performance improvements.
• Implemented the Spatial Audio sound API, fixing Cyberpunk 2077 world sounds.
• Updated vkd3d-proton to 2.1, fixing Cyberpunk 2077 facial animations.
• Improvements for non-US keyboard layouts.
• All other changes from 5.13-4.

As always you can find Proton info on GitHub and on our dedicated page.
