In anticipation of the release of the Steam Deck portable game console, which will take place on February 25, Valve has released a new version of the software Proton count 7.0. It adds support for Epic’s Easy Anti-Cheat system, which will allow you to run even more games on Linux in general and the upcoming console in particular.
Remember that Proton allows you to run Windows-only games directly in the Linux Steam client. The package contains the implementation of DirectX 9/10/11 (based on DXVK package) and DirectX 12 (based on vkd3d-proton), working by translating DirectX calls to Vulkan API, provides improved support for game controllers and the ability to use full screen mode in games regardless of the supported screen resolution.
Proton 7.0 adds support for local H.264 video decoding, improved support for Steam controllers in games launched from the Origin platform, and other improvements and bug fixes. It’s also worth noting that the Linux-based Steam Deck console now supports it 630 games from the Steam library. 356 games are marked as manually verified by Valve staff (Verified). 274 of the tested games do not have a native Linux version and run with Proton.
Valve is also finalizing a new version of Variable Rate Shading (VRS) for the Linux open source graphics driver, which should be available on Steam Deck in May or June this year. This technology allows you to dynamically change the resolution of image details when high quality is not required. This, in turn, reduces the load on the GPU, improving performance while also resulting in lower console battery consumption. The effectiveness of VRS technology depends on the game and the environment. For example, if there is a large number of unique objects with different details in the frame (e.g. grass), the benefit will be less noticeable. At the same time, VRS efficiency is higher in a frame with many identical general objects (buildings, roads).
