Yesterday, Valve released a new Steam client beta that includes a significant change for Linux users. The updated beta client now defaults to using Proton for all non-Steam Windows binaries. This means that Windows-based applications and games not purchased through the Steam store will automatically attempt to run with Proton enabled, removing the previous requirement for users to manually configure each non-Steam title for compatibility. This update, described by Phoronix as a "notable improvement for Linux users," aims to streamline the process of running a broader range of Windows software on Linux, enhancing overall compatibility and user experience.
