"Unreal Engine 5's Lumen system can impede performance; however, by utilizing only dynamic lighting and innovative techniques, it's possible to achieve impressive visuals without certain features."
"Pasquale Sciontiâs UE5 tech demo showcases performance-optimized techniques using local exposure and tonemapping, achieving 120fps on RTX4090 while avoiding Lumen and baked lighting."
Unreal Engine 5 continues to evolve game design, with Lumenâs global illumination providing impressive visuals but potentially hindering performance. Cinematic light artist Pasquale Scionti showcased a tech demo using only dynamic lighting without Lumen, Pathtrace, RTX, or baked lighting. By employing Nanite, distance field meshes, and Ambient Occlusion along with local exposure techniques, Scionti created a demo influenced by Blade Runner and Cyberpunk. The result showed 120fps performance on an RTX4090 at 4K epic settings, demonstrating the capabilities of Unreal Engine 5 without its high-profile features. The demo is available for download despite high demand.
