In this post series, we measured the cost of additional Cameras in Unity’s Built-in Rendering Pipeline and Universal Render Pipeline. The results clearly show that unnecessary Cameras in a scene have a cost that can easily be avoided for a nice performance gain.
On a closing note, you might wonder why even a Camera that doesn’t render anything can have such a large performance impact. The first main reason is that it simply takes a good amount of work for Unity to figure out that the Camera does not, in fact, contain anything. The second reason is, to put it bluntly, that Unity is not optimized for sub-optimal Camera setups. Optimizing the engine for these would make the well-configured games slower and also probably use more memory which is undesirable.
