Nintendo Switch 2 faces significant performance limitations when running Unreal Engine 5 titles due to CPU constraints. Digital Foundry experts analyzed current UE5 games on the platform and discovered missing flagship features. Cronos The New Dawn, Fortnite, and Split Fiction all lack Lumen and Nanite technologies that define the engine. The absence of these features in Fortnite particularly demonstrates how the engine currently lacks optimized presets for Nintendo's hardware. Transition zones within Fortnite reveal frametime problems that would worsen with demanding UE5 features enabled.
The Switch 2 CPU operates considerably slower than PlayStation 5 and Xbox Series processors that originally guided UE5 development. Games struggle with traversal stuttering and performance issues when running on hardware similar to the Ryzen 5 3600. Epic Games must create dedicated optimization profiles and engine updates to enable Lumen and Nanite functionality at acceptable framerates. CPU limitations extend beyond UE5 titles, as demonstrated by Elden Ring Tarnished Edition's Gamescom demonstration. Additional optimization work remains necessary to achieve playable performance across multiple game engines.
