Clair Obscur: Expedition 33 is the second Unreal Engine 5-powered title to launch this week. The game leverages the entire UE5 suite, including Lumen, Nanite, Niagara, and Virtual Shadows. Despite that, it runs better than the Oblivion Remake. Perhaps due to its smaller environments and aggressive culling rate.
