Editor crashes when using DX12 and/or Ray Tracing?

I’ve been looking to try out the ray tracing stuff in 4.22 but when I start the editor in DX12 mode it crashes either on launch or when I open an asset like a material or object.

When I run the same project outside of DX12 mode it seems to open and run fine.

There are a lot of messages in the output log saying :

LodD3D12RHI: Display: Root signature created where the root parameter akes up 16 DWORDS. Using more then 12 WORDs can negatively impact performance depending on hardware and root parameter usage.

I don’t see those messages when I open the project outside of DX12 mode

Anyone got any ideas? I’ve got the latest drivers and windows 10 version 1809 so as far as I can tell everything should be working

I just found a solution. If you have the nvidia dlss plugin enabled, then just try to disable it. It helped for me.
