AAA Gaming on Asahi Linux

Fantastic! A great proof of concept on Linux - lots of AAA gaming is already possible on Mac with Crossover and/or Parallels or VMWare Personal, which is free! While I have a Steam Deck, gaming on Mac works for me - I refuse to play Baldurs Gate 3 on a controller.

I know it's an extremely un-Apple-like thing to do, but I really wish Apple would team up with Valve to work on Proton, and bring full Proton support to MacOS.

Bringing Proton to Mac would involve either Apple making amends with Khronos and supporting Vulkan, or Valve making the substantial effort to port Proton to Metal natively, or doing DirectX-to-Vulkan-to-Metal translation with MoltenVK. None of those sound very likely or optimal to me.

Besides, the main reason Valve is investing so heavily in Linux and Proton is so their destiny isn't tied to someone else's platform. MacOS is just another someone else's platform like Windows is, with the same threat of getting rug-pulled by a first-party app store that spooked Gabe Newell[1] into investing in Linux in the first place.

Apple already provides their Game Porting Toolkit which includes a D3D12 to Metal translation later for Wine, and it has been integrated into user-friendly Wine distributions like Crossover since last year. There's not much Proton has to offer over what's already available.
