Unity3d触屏旋转刚体模型，当手指拿开时会卡顿一下

Question

想写一个触摸屏控制物体的惯性旋转

if (Input.touchCount <= 0)
        {
            return;
        }
if (1 == Input.touchCount)
        {
            Touch touch = Input.GetTouch(0);
             deltaPos = touch.deltaPosition;
            print(deltaPos);
            Vector3 Torque = new Vector3(deltaPos.y, -deltaPos.x, 0);
            transform.GetComponent<Rigidbody>().AddTorque(Torque);
        }

现在问题就是，当手指拿开时，会有一瞬间的卡顿，请问如何解决？
