Hi,
after upgrading to PL 4.1 a export to JPG (HTML resolution) takes ages! In my case it was 4 ½ minutes for just one picture (source: Nikon NEF from D750; 28,3 MB).
Specs of my MacBook Pro 2015 see screenshot attached.
There’s obviously a new bug coming with this version.
Thanks for the hint - indeed, it’s a difference like day&night (6 pics in just 38 sec.). w/o DeepPRIME it’s a matter of seconds vs. up to 4 min for one picture - really strange, how much this functionality consumes of processing power.
