Player look - inconsistent sensitivity

I am calling my script from update method.

Code (CSharp):

1.  
2. private void HandlePlayerLook()
3. {
4.     transform.Rotate(0, Input.GetAxis("Mouse X") * lookSensitivity
5.         * Time.deltaTime, 0);
6.     playerCamera.transform.Rotate(-Input.GetAxis("Mouse Y") * lookSensitivity
7.         * Time.deltaTime, 0, 0);
8. }

When I change vertical synchronisation setting (1000+ fps difference), look sensitivity does change too. It becames more sensitive (my test proved that it is like 4 times more sensitive) with sync turned on.

Why does this happen?

 

It should not. Are you sure you're calling HandlePlayerLook only once per frame?

 

Yes, I am sure.

Edit: Strange thing is that with increasing framerate, the sensitivity decreases.

Edit 2: It is somehow caused by Input.GetAxis method. I replaced it with constant and it was rotating with constant speed, even when framerate changed.

 

Got it! Input.GetAxis is already independent on framerate, so multiplying it with Time.deltaTime makes it not work properly.

 

Thank you so much! I spent so much time figuring out why I had problems. Finally camera movement works flawlessly.
