dxvk-async VS MoltenVK

Right now im using this https://github.com/Sporif/dxvk-async with dxvk.enableAsync=true, it works but i got transparent assets 1-2s before it load completely, is that normal?

You can also manually install it yourself, check the DXVK_ASYNC Github page for the instructions. Maybe try to use an older version of Proton GE if you're unsure.

I also tested out Unity on my system and got the same results as you to which DXVK gplasync or the older DXVK-Async "band-aid" fixed it. Really, that's the only thing that does address issues with DX11

DXVK Async: This is a file that converts the game from DirectX9 to Vulkan, this helps alleviate issues with stuttering and massive frame drops. This version has async which renders shaders faster so it has less stuttering than regular DXVK.

Try downloading this - https://github.com/Sporif/dxvk-async

Download dxvk async 2.0 here : https://github.com/Sporif/dxvk-async/releases/tag/2.0. then open it and go inside the x32 folder and copy d3d9.dll and dxgi.dll then paste inside C:\Steam\steamapps\common\Mafia II\pc.

Jedi Fallen Order (Epic setting) was a little quirky with stuttering, but was rectified when I used DXVK_ASYNC and entered DXVK_ASYNC =1 in Settings > About > Advanced System Settings > Advanced Tab > Environment Variables > System Variables > New > Variable Name = DXVK_ASYNC, Variable Value = 1, and that reduces the issues quite a bit. Vanilla DXVK 2.1 didn't work out as well for me, but I might try it again as 2.2 came out recently

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.
