Theoretically it could, although: > The main Proton issue is that it runs on DXVK, and MoltenVK is not always up to parity with implementing Vulkan API calls on Metal reliably. https://github.com/ValveSoftware/Proton/issues/1344#issuecomment-1093053454 https://github.com/ValveSoftware/Proton/issues/1344#issuecom... An alternative would be using CrossOver (which pulls from Wine and adds stuff like MoltenVK), which is what Proton does as well (pulling from Wine and adding stuff, but not MoltenVK) and vendors internally, Valve "just"† doesn't pull from the CrossOver changes nor expose Proton on macOS. † scare quotes because it may not be as easy as it seems
