Crash: d3d12: could not create a pipeline state object

Unity Engine
1

Hi,

I tried building with the new Graphic Jobs setting enabled and DX12 but I get 100% crash on three setups.

  • Surface Book running on HD 250
  • Surface Book running on Nvidia 940M
  • Desktop running on Nvidia GTX 960

Message in the log is: Crash: d3d12: could not create a pipeline state object
Also in the error log: nvwgf2umx.dll caused an Access Violation (0xc0000005)
in module nvwgf2umx.dll at 0033:a8e31def.

Problem is that I can’t reproduce the issue on an empty project… Does anybody know what might be causing this?

(still working on pinpointing the problem, will come back here with more details)

Update 1: Definitely not linked to Graphic Jobs. So must be a DX12-specific issue. Now trying with a different startup scene.
Update 2: Not scene specific. Crashes straight up at boot. Project is 30 gb in size, no way I can send this whole thing to Unity and expect them to download and open it…

Do you call WarmupAllShaders by any chance? If so, could you try without it?

No unless one plugin dll is calling it there shouldn’t be anything calling WarmupAllShaders. This call actually caused 5 minutes scene loadings on Mac and Linux so we made sure to search and remove any usage of this method.

Does the “Preload Shaders” checkbox does this? I just unchecked it and started a build. Will see if that’s the case.
