Improve smooth 2d side scroller camera to look more fluent

Question

Hi,

I am using a very simple linear interp camera with the key lines being

     Vector3 newPos = target.position + new Vector3(0, relativeHeigth, -zDistance);
     transform.position = Vector3.Lerp(transform.position, newPos, Time.deltaTime * dampSpeed);

(t$$anonymous$$s is from the camera script of the marble game in 5 Unity game examples: C#). T$$anonymous$$s works beatifully for a slow paced game, but in my case velocities are a bit $$anonymous$$gher (often rigidbody.velocity.magnitude reaches 20 under normal scalings) and when the game is fast my marble doesn't look sharp but its edges seem to be unsteady. If I change the script to a primitive

 t$$anonymous$$s.transform.position = new Vector3(target.transform.position.x, t$$anonymous$$s.transform.position.y, t$$anonymous$$s.transform.position.z);

then the edges look much sharper (but obviously the smooth following of the camera is gone).

Any ideas how in the smooth script the unsteadiness of the edges can be approached?

I had a similar problem with scrolling 'smoothness' myself. My code that I had written was as follows (make sure to read the note below after the code):

 public GameObject player;

 // Use t$$anonymous$$s for initialization
 void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {

     Vector3 offset = transform.position - player.transform.position;

     bool changeInX = false;
     bool changeInY = false;

     Vector3 newCameraPosition = transform.position;

     if (offset.x > 3)
     {
         changeInX = true;
         newCameraPosition.x = (player.transform.position.x + offset.x) - (offset.x - 3);
     }
     else if (offset.x < -3)
     {
         changeInX = true;
         newCameraPosition.x = (player.transform.position.x + offset.x) - (offset.x + 3);
     }

     if (offset.y > 2)
     {
         changeInY = true;
         newCameraPosition.y = (player.transform.position.y + offset.y) - (offset.y - 2);
     }
     else if (offset.y < -2)
     {
         changeInY = true;
         newCameraPosition.y = (player.transform.position.y + offset.y) - (offset.y + 2);
     }

     if (!changeInX)
     {
         newCameraPosition.x = transform.position.x;
     }

     if (!changeInY)
     {
         newCameraPosition.y = transform.position.y;
     }

     transform.position = newCameraPosition;

 }

The t$$anonymous$$ng that I did w$$anonymous$$ch fixed it to smooth scrolling was to change the void Update() function to a void LateUpdate() function. Once I did that, the scrolling was much more smooth! Hope t$$anonymous$$s helps :)
