ares VS MoltenVK

ares, takes 2 minutes to compile if it isn't in the app center, or whatever.

There's great retro console games you probably missed out. You might want to learn how to use an multi-emulator like Ares however I must warn you in advance, emulation is a legal gray zone, and a licencing hell.

Ares is a multi system emulator which you can use on Mac, it has support for Nintendo 64 games!

ares is another option to explore if you're unaware of it - [https://ares-emu.net]

Try ares: https://ares-emu.net/

that one is old and missing aarch64. here's the latest https://github.com/ares-emulator/ares/tree/master/libco

ares is a very accurate N64 emulator (similar to simple64) that has built-in shader support including at least 2 different CRT filters

Translating between rendering APIs is not really the problem. The GPU design is more different than the API is.

Khronos maintains MoltenVk though, which is "official" as it gets: https://github.com/KhronosGroup/MoltenVK

...technically, Vulkan on Windows is also only supported via 3rd-parties (the GPU vendors), Microsoft doesn't support Vulkan either ;)

MoltenVK implements large parts of Vulkan on top of Metal for Apple systems. It isn't full Vulkan but it makes porting Vulkan games to OS X easier.

That's cool. Maybe I haven't thought enough about this. Let me check it out. FWIW it's this PR that you are referring to I think: https://github.com/KhronosGroup/MoltenVK/pull/1815/

For Metal specifically, they could adopt and contribute to Vulkan and get access to a lot more software. Right now you need to use a compatibility layer, and surely Apple could just support both APIs natively with much lower overhead. But they don't, because it nudges developers to stick to the Apple ecosystem instead of being able to support multiple platforms.

At the moment the most promising thing is MoltenVK (DX12 -> DXVK -> Vulkan -> MoltenVK -> Metal), but the development is not that quick mainly because there aren't tons of developer that works at the same time on the project. It's not actually a Metal related problem at the moment (they have a road map of things that they can be achieved with Metal 3 like Mesh shader and Geometry shader).

What you asked is already existed for at least 8 years. Yeah EIGHT years. It's called "MoltenVK". So far it's the only implementation of Vulkan for macOS. Basically it's a wrapper that runs on top of Metal API.
