I’ve been doing some experimentation with the FixedUpdate function in Unity and it appears to run at a different speed in the editor than on the device (iPhone 4). Is it capped on the device? And if so, at what speed? Can this be adjusted in Xcode?
FixedUpdate runs at whatever you set it to in the Time settings. e.g., .02 is 50 fps. The only way it would be different depends on what you have Maximum Allowed Timestep set to in combination with the framerate on the device.
