High GPU usage in PL7.5 on Exports with no corrections applied

PL7.5 / Win11 / i7-14700kf + RTX-4070 here.
I’ve just noticed that export to jpegs uses GPU intensively, even though no corrections were applied. I thought that previous PL versions used GPU for DeepPRIME only. Was there a quiet change recently (‘minor fix’)?

Yes, since 7.5, PhotoLab is making overall better use of GPU (and CPU too) under Windows. Don’t know about MAC.
