MoltenVK VS Vita3K

https://github.com/KhronosGroup/MoltenVK

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.

Don’t know about any ports, only Vita3K emulator that’s steadily improving: https://vita3k.org

Vita3K, it's a cross-platform Vita emulator. And as the Quest runs Android, you can simply download the Android version and either sideload it into the Quest or if you already have a file manager installed in your Quest, just access the site directly from your Quest, download it and install.

Android emulator Vita3K got new update, and now Persona 4 Golden runs very well on it, no more crashes or lags.

I would never ever do anything so bad but just so you don't use it here is one for P4G

For those who wish to "properly" report for android specific issues, put in the Android Repository or if its a game specific issue, the Compatibility repository not in the Main Repository.

Yeah https://vita3k.org/

If you genuinely care about a fix for the game, you're better off assuming nobody has the answer to minor issues like these and instead creating an issue (if it doesn't exist yet) on the Vita3K Github, and adding as MUCH information as you can. Logs, Full Device + Driver Information, what worked, what didn't, etc. https://github.com/Vita3K/Vita3K/issues
