I guess I didn't clarify, but there comment from the previous user had stated that on the new M Series chips that running Linux is better for gaming on those devices (ala Asahi Linux).
No doubt Proton on normal x86 Linux PCs is great. My primary desktop and ROG Ally has been painless (aside from some old games that have issues regardless of OS).
But Proton is still buggy on Asahi Linux (support was literally announced a week ago or so). Meanwhile of the games I run on Steam, only a handful needed Crossover or Whiskey for macOS.
What Steamymoomilk had stated previously is that Linux on Apple Silicon is better than macOS for gaming. But Proton support is not only a very new feature to Asahi Linux but also still has issues.
x86 Linux > macOS (with or without Crossover) > Asahi Linux on Apple Silicon macs (what the previous commenter said was better than macOS).
