The culprit was not a lack of developer care, but the reality of the Switch’s 2015-era mobile chipset (the NVIDIA Tegra X1) attempting to run a game built on Unreal Engine 5.1. Funko Fusion uses dynamic lighting, physics-based destruction for its “Corrupted” enemies, and a persistent inventory of cosmetic items. For a PS5 or Xbox Series X, these are minor luxuries. For the Switch, they are a sustained assault on memory bandwidth.
