I must admit, I don't do gaming on my Linux rig, but ... aren't there major 3D games being published for Linux via Humble Bundles, Steam, GoG, and no doubt others as well? Is this a support nightmare for those companies? And if not, how is it that they can work with GPUs in Linux, but the living gods of code over at Google can't hack it? I'm at work and can't be bothered to look up compelling examples, but I'm pretty sure The Witcher 2 runs on Linux, and that's a pretty GPU-intensive title. When something like this doesn't add up, it usually means I'm missing something. Like maybe Witcher 2 requires a specific distro that uses proprietary drivers or something, but Google's talking about Linux in general? Can anyone clue me in?
