Photo AI Remove Tool - performance

Hi there, I’ve tried to search the forums in case anyone else has asked this but I can’t see anything.

I like the new ai tool for removing objects, but I’ve noticed that it relies heavily on the CPU. On my main computer with 8 cores this is not ideal, but ok, but a secondary system that I have uses 4 cores that are quite old. I’m mildly surprised that the GPU is not utilised as on both computers processes that do use them are very fast indeed.

Am I missing a setting somewhere or is this normal utilisation?
If it is normal, will there GPU be used in the future?

Thank you for reading.
