I would expect the framerate to go down as FOV increases since you’re rendering more on the screen but I’ve made a simple zoom lens for drone cameras in my game that are supposed to go up to 30x and I can’t get the FOV that low before hitting 12fps. Its a pretty linear scale, too. I get 60fps at FOV 90, 30fps at FOV 45 and so on.
Does anyone have any advice at all on how I can save frames with these extreme zoom levels? My client is asking for realistic zoom capabilities.
