I’ve also tried adding a shortcut as shown in this video ([UE4 - Introduction to Realtime Raytracing (RTX Overview) - YouTube](https://youtu.be/-zvnW8BoI2w?t=79)) so renaming the UE4Editor.exe shortcut to have " -DX12" in there but each time i check in the corner it’s showing it’s using DX11…

I have attached some screenshots to show some details.
