COD11 sensitivity setting?

[destru]

Should i set the sensitivity to insane 20 in COD11, although it's ok for using a mouse, but i found it too fast for a controller.

For a mouse controlling, setting the sensitivity ot 20 can bring you the best control. You can have a fast turning around and a steady aiming at the same time.

And it will feel fast, if you change back to controller.

A mouse and a controller will need two different sensitivity, due to that they have different speed of their own.
