Yes. It appears that if you’re running a Win10 build prior to 1809, some of the Raytracing settings will appear in engine, however, they won’t actually work. You have to run Win 10 build 1809 (or later).
For a summary, this is what’s needed:
- RTX Card (DX12 Supported)
- Win 10 Build 1809 (or later)
- Command line “-dx12” added to Engine Shortcut
- “Raytracing” Enabled in Project Settings
