I noticed a huge time difference between exporting image with predefined AI mask (sky for example) and same image but sky masked with generic AI mask: 1 min 11 s Vs, 5 s! And during export with predefined sky AI mask my notebook freezes for some time (I9-185 32 GB RTX4070). Obviously export with predefined AI mask almost eat all of the notebook resources!?!
Have you done this test several times ?
I noticed that the first export always takes longer.
There will still be a difference but less significant.
