Syncing movement and rotation lag in complete scenes

Hello everyone,

I have a room that uses PUN 2, where two agents connect and wander around the scene. I am using the first person controller from Unity standard assets without a rigid body but a character controller. However, the problem is that when the agents connect in a complete room with assets and lighting the movement of the other client (the one we watch as players) has quite some lag. When I tried in a room with just a cube as ground everything works fine and no lag at all.

I have implemented lag compensation based on the documentation using the transform component. Here is the following code :
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();
        }
    }
and the update function
void Update()
    {
        if (!photonView.IsMine)
        {
            transform.position = Vector3.Lerp(transform.position, networkPosition, Time.deltaTime * 5);
            transform.rotation = Quaternion.Lerp(transform.rotation, networkRotation, Time.deltaTime * 5);
        }
    }
All this belongs to the script that is inserted as input to the PhotonView component. Last but not least, the profiler when running the scene shows an average of 70-80 fps so I guess its not the environment that creates the problem.

  • PUN is typically running with 10 updates/sec. Unless the game is below 10 frames, you should not notice this, especially, as you don't seem to send a lot of data per update.
    I'm sorry but there is no simple explanation to this.
