Switching to either Vulkan or Direct3D12 causes editor crash

News & General Discussion

Ok so its 2019 now.
So whats the scoop with Direct3D12 or Vulkan? Has anyone compiled a list if Unity versions, build targets and compatibility?
Right now using Unity 2018.3 targeting Windows desktop, whenever I switch to either Vulkan or Direct3D12, the editor crashes!

I have also ran into problems with Direct3D12 and Vulkan. I launch the Unity editor with a flag to force DX11, and that really helps editor stability. In standalone builds, Direct3D12 is unreliable (visual problems) on Windows and Vulkan is unreliable on Android (blank black screen). I don’t think Unity has committed to getting Direct3D12 and Vulkan working reliably.

There are several modern features that are stuck in permanent preview mode instead of getting polished for production. Direct3D12, Vulkan, full 64bit support (32bit scene file limit), GFX jobs, etc. These features are not production ready at all.

Especially Vulkan, you can’t make it 1 minute in the editor without it crashing.
Looks like they’ll still be experimental for ages to come.

Yeah, Vulkan is a permanently experimental feature in Unity. It will never be production ready in Unity.

Same problem here. For me it used to be that resizing panels was just really slow until it randomly crashed one day and I made a bug report. Followed the instructions in the response in the email reply and now it constantly crashes no matter what I do while it’s both DX12 or Vulkan. Tried a clean reinstallation of Unity 2019.2.1f1, clean install of Nvidia Studio drivers, even tried directly downloading the Vulkan SDK and Runtime libraries and still it crashes. Funnily enough Unity 2018 had much more stable Vulkan editor and builds.

If I were to venture a guess, I’d say that Unity has prioritized work on SRP and DOTS over finishing work on the experimental graphics API’s.

My understanding is there isn’t much benefit to DX12 unless the engine takes a completely multithreaded approach, which I don’t think Unity will be ready for until after DOTS is ready (totally unsubstantiated wild speculation on my part).

Can we get bug reports for these issues?
