Pixel Streaming with DX12 enabled for Raytracing not working

Siqm8 · July 25, 2019, 3:10am

Hi guys,

I can’t seem to get pixel streaming working when I set the default RHI to DirectX 12, as I require it for Raytracing.

Once I enable it, the server just stops seeing the application launching so Pixel Streaming doesn’t work. Changing the RHI or Forcing DX11 via -DX11 gets things working again, but without Raytracing!

Tried in 4.22 too and still didn’t work. Is this a limitation or a bug? I can’t seem to verify if its not meant to work on the Pixel Streaming reference!

Thanks!!

Same problem, it seems they dont support it yet. But it would really useful, if they would write this requirement in the docs

I have traced the problem down to nvencoder, nvencoder has a dependency on DirectX SDK and I believe microsoft never update it to DX12.
I have tried to port a DX11 device to DX12 by D3D11On12 however it doesn’t work.
I hope it will work soon.

FYR

Just to confirm that pixel streaming doesnt support raytracing due to dx12 being unsupported.

Today’s output log when opening up a RT scene.
