Demo of new Unreal game engine is unreal

"Lumen in the Land of Nanite" is a real-time Unreal Engine 5 demonstration running live on PlayStation. The new UE5 has two technologies: "Nanite virtualized micropolygon geometry, which frees artists to create as much geometric detail as the eye can see, and Lumen, a fully dynamic global illumination solution that immediately reacts to scene and light changes."
