Did not get choppy movement fixed

Options
I have setup up my char with this settings:

public class NetworkPlayer : MonoBehaviourPunCallbacks, IPunObservable
{
 
   
    private Vector3 networkPosition;
    private Quaternion networkRotation;
    private float smoothing = 10.0f;
 
 
    // Start is called before the first frame update
    void Start()
    {
        if(!GetComponent<PhotonView>().IsMine)
        {
            Destroy(GetComponent<SplineFollower>());
            tag = "OtherPlayer";
        }
     
        networkPosition = transform.position;
        networkRotation = transform.rotation;
    }
 
      void Update()
    {
        if (!photonView.IsMine)
        {
         
             transform.position = Vector3.Lerp(transform.position, networkPosition, Time.deltaTime * smoothing);
             transform.rotation = Quaternion.Lerp(transform.rotation, networkRotation, Time.deltaTime * smoothing);
        }
    }
 
 
 
 
    /// <summary>
    /// Used to customize synchronization of variables in a script watched by a photon network view.
    /// </summary>
    /// <param name="stream">The network bit stream.</param>
    /// <param name="info">The network message information.</param>
    public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
    {
     
 
       
        if (stream.IsWriting)
        {
            stream.SendNext(transform.position);
            stream.SendNext(transform.rotation);
        }
        else
        {
            networkPosition = (Vector3)stream.ReceiveNext();
            networkRotation = (Quaternion)stream.ReceiveNext();
        }
    }
}
i have tried changing the smooth factor, but without success, the movement is local horrible :(

Here is a video with my problem:

I setup the player so:

Here is an image of my setup:

The cyclist moves smoothly in SinglePlayer Mode

The Player moves with a fixedUpdate on a spline (dreamteck spline)
may be i need to deactivate the remote scripts on client side?
