HDRP on Vulcan - Windows OR Android

Unity Engine

Hi,

According to the docs for 14.0.0, HDRP should be able to run on Windows with Vulkan. But it’s not working. Any idea when that will happen?

Also, a previous version of the docs said that for Android, it is scheduled to work “in the future”, but that only on mobile GPUs that support compute shaders. I have a mobile device that supports compute shaders, and no luck with HDRP.

Any ideas of when in the future HDRP will be available for Vulkan / mobile?

Thanks.

What does HDRP have that you want for mobile?

Hi,

Windows with Vulkan. But it’s not working. Any idea when that will happen?
Could you please be more specific, we have constant test running on linux vulkan and windows vulkan and all is fine for us. (PC).

HDRP is not supported on mobile currently and we don’t have any ETA for it. The mention have been remove from the documentation.

That’s too bad about mobile. Today’s mobile GPUs have compute shader capabilites, which is what earlier HDRP docs stated was required. One could argue that for games on small device screens perhaps HDRP is not critical, but for VR and AR, where the eyes are much closer to the display in the VR headset and photorealism is (arguably) more important, HDRP could be important. IMHO. But I understand there may be higher priorities from your p.o.v.

Repro steps:

  1. Viking Village URP from the asset store. Download, import, install.
  2. Go to player settings, remove DirectX, add Vulkan. In my case, I added OpenGL Core for PC, but after you asked for details, I added Vulkan, and moved it above OpenGL Core.
  3. Crash when Editor tries to render in the Scene window. See pic below. The Unity version is also displayed.

Hey, thanks for the report. I tried on latest engine version 2022.2 on URP and 2020.3.31f1 on URP too.
Unfortunately, I have not been able to repro on either of thoses versions.

What could help us is to have a look on the crash bug report.
Do you by any chance have access to it?
It should be located around here on your machine:

C:\Users\<your_username>\AppData\Local\Temp\Unity\Editor\Crashes

Thanks!
Here’s a capture of it working on vulkan on my side.

I submitted the bug report using the Editor’s own crash report tool. I’m guessing it’s probably a bug in the graphics drivers. I’m on a Quadro, not Geforce, maybe that is a factor (even though it shouldn’t be).
