How to fix multiplayer stuttering?

For some reason the other player's movement is 'stuttering'. I know this is a common problem people run into with Photon, so was wondering if anyone knows how I can resolve it?

Here's my player movement code:

public float SmoothingDelay = 5;

public void Start() 
{
    GetComponent<SmoothSyncMovement>().enabled = true; //This is the name of this script
}

public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
{
    if (stream.isWriting)
    {
        //We own this player: send the others our data
        stream.SendNext(rb2D.position);
        stream.SendNext(rb2D.rotation); 
    }
    else
    {
        //Network player, receive data
        correctPlayerPos = (Vector3)stream.ReceiveNext();

    }
}

public void Update()
{
    if (!photonView.isMine)
    {
        Vector2 playerMovement = rb2D.position + velocity * Time.deltaTime;
        rb2D.MovePosition(playerMovement);          
    }

    if (photonView.isMine)
    {
        Vector2 playerMovement = rb2D.position + velocity * Time.deltaTime;      
        rb2D.MovePosition(playerMovement);
    }
}

Make a smooth transition between players old possible and new position, dont set position. You can use lerp for this or any other method.

It would look something like this:

currentPosition = Vector3.Lerp(currentPosition, realPosition,0.1f);

Where currentPosition is the position of the networked player before it moves on your client and realPosition is the new position received from the network where you want the player to be.
