An anonymous reader writes: Today marks three years since Valve's Steam client went into beta on Linux. In that time over 1,600 games have become natively available for Linux. Going beyond having many new Linux games, Phoronix recaps, "we've seen Valve make significant investments into the open-source graphics stack and other areas of Linux (in part through their sponsorship of Collabora and LunarG). Valve developers are significantly pushing SDL2. We've seen more mainstream interest in Linux gaming, and Valve has been heavily involved in the creation of the Vulkan graphics API. They have given away their entire game collection to the Mesa/Ubuntu/Debian upstream developers, and much more." The three-year anniversary is coincidentally just days before the release of Steam Machines.
