Lighting in UE5 - Scaling for Quality and Performance

Learn advanced lighting optimization techniques in Unreal Engine 5 through this 36-minute conference talk from Unreal Fest Bali 2025. Discover how Alexis Argyriou from The Bureau Consulting dramatically improved performance on the modern hero shooter 'BADMAD ROBOTS' from 22 fps to over 120 fps while maintaining visual quality and scaling down to run on last-generation laptop chipsets. Explore his innovative approach to running Lumen on high-end devices while switching to pre-baked lighting for low-end hardware, understand the challenges of working with static lights in Lumen, and learn creative solutions for handling overlapping stationary lights and hidden VFX costs. Master the use of Unreal Engine's built-in profiling tools like Unreal Insights to carefully monitor GPU performance and optimize your lighting pipeline for both quality and performance across different hardware configurations.
