Kernel-level anticheat and DRM are killer features, like it or not. People don't care how invasive they are, they want to play League of Duty. If Linux can't do that then it's not good enough yet as far as they are concerned.
Meanwhile the only thing keeping me from switching to Garuda on my desktop is that the GPU is wonky and misbehaves even worse under Linux than it does under Windows. Screw competitive online games.
