Bananza targets 60 frames per second, but it's not quite consistent - especially on the map view, where performance ping-pongs rapidly between 30fps and 60fps: classic double-buffer v-sync. Also the photo mode view appears to drop to 30fps more frequently than main gameplay, which suggests it's using a higher resolution, or settings, than the regular gameplay.
Also, there seem to be different frame-rates in gameplay. The target is 60fps, but there are noticeable drops. Not only that, but some physics-based interactions – like any time DK punches a fence or barrel to the distance – may see animation update at closer to 30fps, while the foreground gameplay updates at 60 as usual. It looks like some physics-based logic runs with a frame rate cap, creating a disconnect between the camera movement – which runs at 60 – and the objects within the frame.
