I'm not sure which side of the discussion you're on from that reply, I was fairly balanced. I can try to restate again..
- linux gaming on amd is awesome with steam/proton
- linux gaming on nvidia is generally substandard but works well for some people
- Gaming is still generally more performant on windows
- The article title is misleading. A few specific games on a specific device ran faster on Linux than on windows. This isn't a large win for anyone except the people who optimised proton for this very specific chipset + processor + video combination.
- SteamOS will be great when it's fully out as a standalone thing and lead to more and more of the above scenarios as it's tuned for more and more devices, but right now it's only out for a handful of VERY specific devices
Which of those are grasping at which straws, from which viewpoint?
