Epic Games has announced that the latest iteration of its Unreal Engine 5 delivers a substantial performance lift for titles targeting the upcoming Nintendo Switch 2.
The new UE5.8 update dropped on Wednesday, just ahead of Epic’s State of Unreal keynote in Chicago, following a brief early‑access phase that allowed developers to test the changes.
In addition to a host of new features, the full release introduces an unexpected “Lite” variant of the Lumen lighting system, which Epic claims will dramatically improve frame rates on Switch 2 by streamlining real‑time global illumination and reflections.
Lumen, the engine’s default global illumination and reflection solution, calculates light bounce in real time, freeing creators from the labor‑intensive process of baking lightmaps into their game worlds.
Epic Games has announced that its newly refined Lumen Lite technology now operates at twice the speed of its predecessor, unlocking the possibility for titles that depend on global illumination to achieve smooth 60‑frame‑rate gameplay on the forthcoming Nintendo Switch 2.
Simon Tourangeau, Vice President of Engineering at Unreal Engine, highlighted that Lumen Lite retains the visual punch of its full‑scale counterpart while dramatically reducing computational overhead.
“This advancement makes Lumen feasible on devices where it previously wasn’t, such as the Switch 2, and it’s already fueling further Nanite optimization for the platform,” Tourangeau added during the State of Unreal keynote.
Several Unreal Engine 5 games, including Epic’s flagship Fortnite, have already launched on the Switch 2. With Lumen Lite’s performance gains, players can anticipate a broader influx of UE5 titles making the jump to the console in the near future.
Games built on Unreal Engine 5—such as Halo: Campaign Evolved, The Outer Worlds 2, Arc Raiders, and Black Myth: Wukong—demonstrate the engine’s growing influence across diverse genres, from first‑person shooters to expansive open‑world adventures.
❓ Frequently Asked Questions (FAQ)
What is Lumen Lite and how does it benefit Switch 2 games?
Lumen Lite is a streamlined variant of Unreal Engine 5's default Lumen global illumination system. It reduces GPU demands by simplifying real‑time light bounce calculations, allowing developers to keep high‑fidelity lighting while achieving smoother frame rates on the Nintendo Switch 2.
How much faster is Lumen Lite compared to the previous version?
Epic Games claims that Lumen Lite operates at twice the speed of its predecessor, effectively doubling the performance of real‑time global illumination and reflections on Switch 2 hardware.
Will the 2X speed boost enable 60fps on Switch 2 for all titles?
While the speed boost opens the door for many graphically intensive titles to target a smooth 60‑fps experience on Switch 2, actual performance will still depend on each game's specific design, optimization, and other system demands.
