Rotation is faster in build

I have this code for rotating the player and camera and when I build the game the rotation is faster.

I guess that’s because of the Time.deltatime but when I don’t multiply the values with the deltatime I get a slower rotation with the controller in the build (although the _rotationVelocity value is the same in the build and the editor)

Here is the code:

    private void HandleRotation()
    {
        float scalingFactor = Time.deltaTime;
        Vector2 mouseDelta = inputManager.inputActions.Player.CameraRotation.ReadValue<Vector2>();

        _cinemachineTargetPitch += -mouseDelta.y * cameraSensitivity * scalingFactor;
        _rotationVelocity = mouseDelta.x * cameraSensitivity * scalingFactor;

        // clamp our pitch rotation
        _cinemachineTargetPitch = ClampAngle(_cinemachineTargetPitch, -maxXRotation, maxXRotation);

        // Update Cinemachine camera target pitch
        cameraTransform.localRotation = Quaternion.Euler(_cinemachineTargetPitch, 0f, 0f);

        // rotate the player left and right
        playerTransform.Rotate(Vector3.up * _rotationVelocity);
    }

The mouse delta shouldn’t be scaled by Time.deltaTime. So instead you’ll need to have two input values and only scale the controller input value by Time.deltaTime.

Why the mouse input shouldn’t be scaled and the controller input should?

The mouse delta is already frame rate independent. Whereas the controller input is in the range of -1 to +1 and so it needs to be scaled to keep the movement rate constant across different frame rates.

Thanks for the explanation, I appreciate it!
