Valve released the Beta of a new and improved version of Steam Play to all Linux users. The Beta version includes a modified distribution of Wine, called Proton, to provide compatibility with Windows game titles. Windows games with no Linux version currently available can now be installed and run directly from the Linux Steam client, complete with native Steamworks and OpenVR support. DirectX 11 and 12 implementations are now based on Vulkan, resulting in improved game compatibility and reduced performance impact. There are a lot of details in this announcement, be sure to read the entry over on the Steam Community website.
