How can I make my cursor to follow more faster? (there's too much delay)

I used script in a cursor object to make cursor's position always be the position of the real mouse pointer.

The problem was that there was always delay of this action so I could always see my actual pointer going ahead of the cursor I made.

I tried this on FixedUpdate, Update, and LateUpdate and only found that FixedUpdate's delay is the least, but nor zero.

How should I solve this problem? Is there totally different way to change the cursor's sprite?
