Hi...
I just did a test with Headshot 2 using a 4K image in Pro mode (CC 4.4). It only took 1 minute to complete (RTX 2080) so it doesn't seem a bug or general issue with Headshot 2.
Have you tried with a few different images to see if the result is always the same? Also if you have a computer that is always left on, please try shutting it down and try the process immediately after a restart with no other apps open. Does it speed things up or does it still take the 4 minutes to complete?
