Unreal Engine 5.8 Introduces Lumen Lite, Aims for 60fps on Switch 2

Epic’s Unreal Engine 5.8 adds Lumen Lite, a low-GPU-cost mode for dynamic global illumination that preserves much of the visuals while enabling around 60fps on Switch 2 handheld (and on PC). The mode uses irradiance fields with probe occlusion and is touted as roughly twice as fast as Lumen High Quality. UE5.8 is described as the last major UE5 update as Epic shifts focus to Unreal Engine 6, with ongoing optimization work for Switch 2.
