Touchinput with drag doesn't work fast

Hi there, I made a TouchInput.js for the camera and a reference to an object. But if I drag my object fast across my screen, it stops the drag because it probably thinks the gameobject isn't touched anymore. Only if I slowly move my object across the screen it works right.

This is the TouchInput script I made for the camera:

         if (Input.touchCount > 0) {
             
             touchesOld = new GameObject[touchList.Count];
             touchList.CopyTo(touchesOld);
             touchList.Clear();
         
         foreach (Touch touch in Input.touches) {
             
             Ray ray = camera.ScreenPointToRay(touch.position);
             
             
             if (Physics.Raycast(ray,out hit,touchInputMask)) {
                 
                 GameObject recipient = hit.transform.gameObject;
                     touchList.Add(recipient);
                 
                 if (touch.phase == TouchPhase.Began) {
                     recipient.SendMessage("OnTouchDown",hit.point,SendMessageOptions.DontRequireReceiver);
                 }
                 if (touch.phase == TouchPhase.Moved) {
                     recipient.SendMessage("OnTouchDrag",hit.point,SendMessageOptions.DontRequireReceiver);
                 
                         
                 }
                 if (touch.phase == TouchPhase.Ended) {
                     recipient.SendMessage("OnTouchUp",hit.point,SendMessageOptions.DontRequireReceiver);
                 }
             }
         }
 
     }

Can someone tell me what I have to change/add? :)
