Shin’en Multimedia is a small but highly talented developer with a reputation for delivering astonishing custom technology. After Fast Racing Neo on Wii U and Fast RMX on Switch, Fast Fusion represents a full-blooded sequel that pushes the T239 processor hard - and in the case of DLSS, perhaps too hard. After this video was completed, Shin’en told us that a “pure” mode that doesn’t use upscaling will be made available in an upcoming patch.
