Delay when drag object from mouse cursor

Hi guys I've found this scrip on web, this is a attacked to my player. it's for simple drag and shot game. It's work fine but i would like that the gameobject follow the mouse cursor always in the center of this. Now there's a delay when I drag it away from the center of gameobject ( Increases the distance between him and the cursor).

Can someone help me?

 public Vector3 gameObjectSreenPoint;
 public Vector3 mousePreviousLocation;
 public Vector3 mouseCurLocation;

public void OnMouseDown() { //This grabs the position of the object in the world and turns it into the position on the screen //gameObjectSreenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position); gameObjectSreenPoint = gameObject.transform.position; //Sets the mouse pointers vector3 mousePreviousLocation = new Vector3(Input.mousePosition.x, Input.mousePosition.z, Input.mousePosition.y);
}

     public Vector3 force;
     public Vector3 objectCurrentPosition;
     public Vector3 objectTargetPosition;
     public float topSpeed = 10;
 
          
     void OnMouseDrag()
     {
        mouseCurLocation = new Vector3(Input.mousePosition.x, Input.mousePosition.z, Input.mousePosition.y);
 
        force = mouseCurLocation - mousePreviousLocation;//Changes the force to be applied
        
         mousePreviousLocation = mouseCurLocation;
         
     }
 
     public void OnMouseUp()
     {
         //Makes sure there isn't a ludicrous speed
         if (this.gameObject.GetComponent<Rigidbody>().velocity.magnitude > topSpeed)
             force = this.gameObject.GetComponent<Rigidbody>().velocity.normalized * topSpeed;
        
     }
 
     public void FixedUpdate()
     {
         this.gameObject.GetComponent<Rigidbody>().velocity = force;
     }
 }
