There are other topics about how certain games won't work, because they require DX12, and DX12 is not possible because Metal does not do some of the functions that are possible with DX12.

There is an app I use that only needs DX11 feature levels, but that uses a DX12 syntax. I gather that DX12 syntax is easier than DX11 syntax.

Would it be possible for Parallels to support DX12 syntax, even if only DX11 feature levels are supported?
 
Metal 3 includes key API features that are compatible with DirectX 12. One is mesh/object shaders. The other is the (very, very recently) removed restriction on argument buffer bind counts (https://developer.apple.com/metal/Metal-Feature-Set-Tables.pdf). Previously, it was at 500k which is shy of 1M that DirectX needs. There was a Reddit thread (https://www.reddit.com/r/macgaming/comments/sjcthy/directx_12_support_on_parallels_desktop) that said this was a blocking issue, but I (1) don't think it would have been blocking in the first place and (2) it has already been fixed. If there's enough user demand, which Parallels maintainers can definitely see there is, they could add some kind of "unsafe" mode that assumes the game dev keeps within 500k. Why would anyone use all 1M slots in the argument buffer anyway? If it crashes at runtime, there are already things that can crash at runtime, especially in a VM.

Besides that, the biggest block may have been things like "geometry shaders" and "domain shaders". That terminology is foreign to me, an experienced Metal developer. The addition of mesh/object shaders as described in the MSL specification may or may not fill that gap in functionality. Another blocker might be BC compression which is unsupported by Apple silicon, but that's part of DX11 (https://docs.microsoft.com/en-us/windows/win32/direct3d11/texture-block-compression-in-direct3d-11) which Parallels already supports. If someone on the staff reads this, I'm curious how you pulled that off. Parallels is closed-source, but perhaps you could explain with a source code sample or a pointer to Metal features used.

I would be most interested if Parallels tackled DX12, Vulkan, and OpenCL at once. See (https://www.codeweavers.com/blog/cj...etting-there-crossover-support-for-directx-12) for some technical limitations of DX12 and Vulkan. OpenCL has been ported on top of DX12, which should make adding OpenCL to Parallels easier. I would like to see that because I'm doing a project with OpenCL and would like to compile it in Windows. Another cool thing would be testing out Microsoft's DirectML backend for TensorFlow, which uses DX12 for compute shaders instead of OpenCL.
 
But only if you added OpenCL 1.2 to that list of APIs. DirectX 12 Ultimate seems unrealistic given the M1's hardware, so I would be find with regular DirectX 12. Alternatively, if CLOn12 is a thing and works on Parallels, I would be fine too.
 
Because Parallels Desktop 15 for Mac supports DirectX 11, this list now focuses on performance issues that can be addressed.

It should be noted that some applications only work on macOS Catalina, where Apple added more functionality with Metal.

Performance is also best on macOS Catalina and ATI Radeon graphics cards.

horizon zero dawn .... please add direct x 12 support. it s a crime in our times do not have dx12 on such powerfull machines like m1 pro , m2 pro , etc
 
Diablo 4 not supported. This is the ONLY reason I would subscribe to Parallels Desktop. Hopefully you will add DirectX 12 support.
 
Hello, i am new to parallels and I have a Question to the DirectX 12 support. I have used the trial version of parallels 18 and looked up the DirectX Analyse Programm and the last point is "DirectX-Version: DirectX 12". So my Question is, why is there an entry with "DirectX-Version: DirectX 12" if parallels does not support DirectX 12? It's very confusing for customers which want to buy parallels and expect to run their DirectX 12 Applications on it... I would prefer either to fix this wrong DirectX Version to 11 or really update to DirectX 12.

I would also buy parallels if there would be a real DirectX 12 support for my Applications!

Maybe someone can clear why Win 11 in parallels says it supports DirectX 12, it thats not true?

I hope it doesn't matter if the picture is in German :)
