Nanite is used in the scene but not supported by your graphics hardware and/or driver. Meshes will not render using Nanite

Your whole system is awesome and yes it’s perfect to use UE5, Nanite, and Lumen. Awesome CPU and GPU.

Nanite uses only DirectX 12 to work from now on said the guys at Epic Games. Here’s a picture I got from one of the users above. I also thank him for this
