How to Optimize Unreal Engine 5 Projects for 120+ FPS | GPU Lightmass Tutorial

In this video, I demonstrate how to take an existing ArchViz Interior project (originally for UE 4.27) and optimize it for Unreal Engine 5 to achieve a stable 120 FPS+. We’ll walk through the entire process of setting up the project, enabling the right plugins, and switching from dynamic lighting to high-performance baked lighting using GPU Lightmass. Download the Asset: ArchViz Interior from Epic Games Marketplace (Free) In this video, I cover: Enabling GPU Lightmass and Hardware Ray Tracing. Optimizing Project Settings (Screen Space Reflections, Disabling Lumen/Dynamic GI). Converting lights to Static and baking lighting on the GPU.
