Not just Proton: Getting to know Valve's new SteamOS compatibility layers

Valve has introduced system-level tools that enable SteamOS to run on Arm chipsets and Android APKs, expanding the platform's compatibility. The tools include a Linux compatibility layer, a Windows compatibility layer, and an Android compatibility layer. The Linux layer allows users to run Linux binaries on SteamOS, while the Windows layer enables the execution of Windows games on the platform. The Android layer, on the other hand, allows users to install and run Android APKs directly on SteamOS. This move aims to increase the platform's reach and provide users with more options for playing games on SteamOS.
