In 2012, Valve's CEO Gabe Newell expressed concerns about Microsoft's control over the PC market due to Windows 8, prompting the company to explore Linux and develop SteamOS. Valve addressed the "chicken and egg" issue of game compatibility on Linux by introducing Proton, a compatibility layer that allows Windows games to run on Linux without separate versions. The company also began contributing to the Linux ecosystem by upstreaming improvements in graphical rendering and developing the RADV open-source Vulkan driver for AMD GPUs. Valve has made SteamOS available for free download and installation on personal computers, aiming to compete with Windows in the gaming sector and promote broader Linux adoption. As a result, Valve has become a significant player in the Linux landscape, enhancing the gaming experience and benefiting the open-source community.
