How do I get good FPS for Server Auth gameplay?

Unity Engine

I’m very confused here.
I followed this files implementation of Server Auth Client Predictive Netcode

and my camera jitters (And the player when turning a little)
I feel it is because the code will only execute every tick

private void Update()
        {
while (networkTimer.ShouldTick())
            {
                HandleClientTick();
                HandleServerTick();
            }
}

Is this a problem with cinemachine? I need my look vector to move smoothly but it jumps a lot because of the tick rate correct?

Maybe someone can help me debug this but I am not sure how I can do server auth looking around at a good smooth speed.

The video may be hard to tell but looking around is very choppy and not smooth.

I send both the move and look vectors to my Move function

 Vector2 moveInput = controls.Player.Movement.ReadValue<Vector2>();
            Vector2 lookInput = controls.Player.Mouse.ReadValue<Vector2>();

            LookInputPayload inputPayload = new LookInputPayload()
            {
                tick = currentTick,
                timestamp = DateTime.Now,
                networkObjectId = NetworkObjectId,
                inputVector = moveInput,
                lookVector = lookInput,
                position = transform.position
            };

Simple test: bump your network tickrate in NetworkManager from the default 30 Hz to 60 Hz or slightly above.

Hi, I changed it to 60 and I still get some jitteryness.
I have realised that is looks smooth in the Scene window and not great in the Game. I feel it is the Cinemachine camera being out of sync with the tick rate. Kind of like how Update and FixedUpdate can create jitteryness.
Is there a way I can fix this so cinemachine is in sync with my tick rate?
