Re: DLSS IS GREYED OUT.

From my understanding, the 30s are supported, but only for 3840x2160 resolutions.

With everything installed and updated, head to the Graphics Setting menu in Battlefield V, enable DirectX 12, restart the game if prompted, click on Advanced Settings, enable DXR and restart the game if prompted, enable NVIDIA DLSS, then scroll down and select a detail level for the "DXR Reflections Quality” setting.
