Linux has never been a hot gaming platform. Valve, creator of the Steam game engine and network, has long wanted Linux to replace Windows as the PC gaming platform. Indeed, Gabe Newell, Valve’s CEO, once said, “Linux is the future of gaming.” That didn’t happen, but Valve didn’t give up on Linux. Now, Valve is doubling down on Linux, by proposing changes to the Linux kernel to make it more gaming-friendly.
