Valve releases Proton 7.0 – A Suite for running Windows Games on Linux

Valve has published the release of the Proton 7.0 project, which is based on the Wine project codebase and aims to run on Linux gaming applications created for Windows and presented in the Steam catalog. The developments of the project are distributed under the BSD license.

Proton allows you to directly run Windows-only gaming applications on the Steam Linux client. The package includes implementation of DirectX 9/10/11 (based on DXVK package ) and DirectX 12 (based on vkd3d-proton ) working through DirectX call translation to the Vulkan API, providing improved support for game controllers and the ability to use full-screen mode regardless of supported in screen resolution games. To increase the performance of multi-threaded games, ” esync ” (Eventfd Synchronization) and ” futex/fsync ” mechanisms are supported.

In the new version :

  • Synchronized with the release of Wine 7.0 (the previous branch was based on wine 6.3). The accumulated specific patches have been transferred from Proton to upstream, which are now included in the main part of Wine. The DXVK layer, which translates calls to the Vulkan API, has been updated to version 1.9.4. VKD3D-Proton, a fork of vkd3d created by Valve to improve Direct3D 12 support in Proton, has been updated to version 2.5-146. The wine-mono package has been updated to version 7.1.2.
  • Added support for local decoding of H.264 video.
  • Added support for the Linux module of the Easy Anti-Cheat (EAC) anti-cheat system, which is used to ensure the launch of Windows builds of games with anti-cheat enabled. Easy Anti-Cheat allows you to run a network game in a special isolation mode that verifies the integrity of the game client and detects wedging into the process and manipulating its memory.
