Unreal Engine 5.8 brings 60fps lighting to Nintendo Switch 2 with new Lumen Lite system

Epic Games has released Unreal Engine 5.8 with a new lighting system called Lumen Lite that runs twice as fast as the previous version of Lumen — and is designed to let Nintendo Switch 2 games using global illumination target 60fps, the company announced at its State of Unreal event in Chicago. As reported by VGC, the update had been in early access before its full release on Wednesday.

What is Lumen Lite and why does it matter for Switch 2?

According to Epic Games, Lumen Lite runs twice as fast as the previous Lumen implementation, making real-time global illumination viable on hardware that previously couldn't handle it. That's a meaningful threshold for the Switch 2, which sits between a traditional handheld and a home console in terms of raw GPU power.

Lumen is UE5's default global illumination and reflections system. It calculates how light bounces around a scene in real time, removing the need for developers to pre-bake static lightmaps into their game worlds. The trade-off has always been GPU cost — and that cost previously ruled out platforms like the Switch.

"LumenLight is designed to preserve much of the visual impact at a significantly lower GPU cost," said Simon Tourangeau, VP of Engineering at Unreal Engine, speaking at State of Unreal. "That makes Lumen viable where it wasn't before, including on Switch 2. And that work is already helping drive further nanite optimisation efforts for the platform."

That last point matters. Nanite — UE5's virtualised geometry system for high-detail assets — is also getting optimisation work off the back of the Lumen Lite effort. The two systems together form the visual backbone of most modern UE5 games.

Which games could benefit from Unreal Engine 5.8 on Switch 2?

Epic's own Fortnite already runs on the Nintendo Switch 2 using Unreal Engine 5. With Lumen Lite now available, developers building on UE5.8 have a clearer path to bringing higher-fidelity titles to the platform without the usual performance compromises.

Games currently built on Unreal Engine 5 include Halo: Campaign Evolved, The Outer Worlds 2, Arc Raiders, and Black Myth: Wukong. None of these have been confirmed for Switch 2, but the performance headroom created by Lumen Lite makes ports more realistic than they were before this update.

There's also momentum building around the Switch 2's third-party library more broadly. A recent dataminer claim suggested Call of Duty on Nintendo Switch 2 could be close, while Nintendo's own software pipeline is filling out — the June 2026 Nintendo Direct confirmed several major titles for the platform.

What remains unclear is whether Lumen Lite will be extended to other mobile platforms, or whether it's been specifically tuned for Switch 2 hardware.

What this means for the Switch 2 as a gaming platform

The Lumen Lite announcement signals something important: major engine makers are treating the Switch 2 as a serious target platform, not an afterthought. When a VP of Engineering at Epic calls out a specific console by name during a keynote, it reflects commercial intent — developers are being told the tools are ready.

For players, a 60fps target with real-time global illumination represents a meaningful step up from what handheld hardware has historically delivered. The Switch 2 already impressed at launch with titles running better than expected; UE5.8 support could raise that ceiling further.

Epic is also building toward Unreal Engine 6, which the company says will integrate AI tools to reduce development workload. The optimisation work happening now in UE5.8 — for platforms like Switch 2 — will likely inform how that next engine handles portable and mid-range hardware.

The timing also puts pressure on rival engines. Guerrilla Games' co-founder is building a European Unreal Engine rival, but UE5.8's Switch 2 support reinforces Epic's position as the default choice for cross-platform AAA development.

Frequently Asked Questions

What is Lumen Lite in Unreal Engine 5.8?

Lumen Lite is a more efficient version of UE5's global illumination system, introduced in Unreal Engine 5.8. According to Epic Games, it runs twice as fast as the previous Lumen implementation at a lower GPU cost, making real-time lighting viable on hardware like the Nintendo Switch 2 for the first time.

Will Nintendo Switch 2 games run at 60fps with Unreal Engine 5.8?

According to Epic Games, Lumen Lite allows games using global illumination to target 60fps on the Nintendo Switch 2. That's a target, not a guarantee — individual games will still depend on how developers implement and optimise the engine for their specific title.

Can Nintendo Switch 2 run Unreal Engine 5?

Yes. Fortnite, built on Unreal Engine 5, already runs on the Nintendo Switch 2. Unreal Engine 5.8 extends that support further with Lumen Lite, making it easier for developers to bring UE5 titles with real-time global illumination to the platform at stable frame rates.

Which games use Unreal Engine 5 that could come to Switch 2?

Games built on Unreal Engine 5 include Halo: Campaign Evolved, The Outer Worlds 2, Arc Raiders, and Black Myth: Wukong. None have been confirmed for Switch 2, but the performance improvements in UE5.8 make ports more feasible than before.

Is Lumen Lite available on platforms other than Nintendo Switch 2?

Epic has not confirmed whether Lumen Lite will be extended to other mobile or handheld platforms. The announcement at State of Unreal specifically highlighted Nintendo Switch 2 as the target platform for this optimisation work.
