2D Character stuttering with a smooth camera

My character is stuttering when I have a smooth camera following me, although this doesn’t annoy me… It annoys the players that play this.

So is there any way to fix this?
The smooth camera looks really good imo and so does it to others, but only the stuttering needs to be fixed and it’ll look great.

using UnityEngine;
using System.Collections;

public class CameraController : MonoBehaviour {

	public GameObject cameraTarget; // object to look at or follow
	public GameObject player; // player object for moving
	
	public float smoothTime = 0.1f;    // time for dampen
 	public bool cameraFollowX = true; // camera follows on horizontal
	public bool cameraFollowY = true; // camera follows on vertical
	public bool cameraFollowHeight = true; // camera follow CameraTarget object height
	public float cameraHeight = 2.5f; // height of camera adjustable
	Vector2 velocity; // speed of camera movement
	
	private Transform thisTransform; // camera Transform
	
	// Use this for initialization
	void Start()
	{
		thisTransform = transform;
	}
	
	// Update is called once per frame
	void Update()
	{
		if (cameraFollowX)
		{
			thisTransform.position = new Vector3(Mathf.SmoothDamp(thisTransform.position.x, cameraTarget.transform.position.x, ref velocity.x, smoothTime), thisTransform.position.y, thisTransform.position.z);
		}
		if(cameraFollowY){
			thisTransform.position = new Vector3(thisTransform.position.x, Mathf.SmoothDamp(thisTransform.position.y, cameraTarget.transform.position.y, ref velocity.y, smoothTime), thisTransform.position.z);
		}
	}
}

Go to Project Settings → Time

Next to Fixed Timestep lower the value to 0.0001
