alt Hacker NewsI wonder if Apple's GPT (Game Porting Toolkit) could added to the macOS Steam client as a compatibility tool, like Proton is in the Linux client.

Apple's GPTK only supports D3D12 -> Metal. In addition, it's ambiguous if 3rd parties can distribute the D3DMetal dylib, as there's no license.
GPTK is mostly a bunch of developer tools for converting to Metal, and the closest it gets to anything like Proton is an "evaluation environment" that is nothing close to Proton's performance. Proton is mostly Wine, and Wine on macOS uses MoltenVK, so it's probably easier to just port Proton.
