proton experimental

Proton Experimental is Valve's rolling test branch for the compatibility layer that runs Windows games on Linux and SteamOS, and the tagged coverage on WindowsForum.com focuses on what each build actually changes. Recent discussion covers Wine Mono 11.3.0 arriving with an ARM64 build of its .NET Framework-compatible runtime, alongside Xalia controller-navigation fixes. The thread draws a careful line between adding an architectural building block and confirming that specific games run on hardware such as Steam Frame, pointing to Valve's Proton changelog and Wine Mono release notes as the sources for version numbers. Expect incremental component updates rather than confirmed playable-game lists.
