I am running Win 10 latest patch, on an Intel i5 2500 with 8GB ram and more some 300Gb of free disc space on my C drive and 400Gb on my D drive. My catalog (converted from Elements 10) has some 6000 images.
It takes about 3 min to load, if I try to edit a photo it takes another 2 mins for the editor to load, Elements 10 was slow but nothing like this.
After install and reboot my pc froze for some 20 mins, and has taken 3 reboots to return to some form of performance even when it is the only app running.
It has currently decided to analyze all the photos for faces in my catalogue , why I did not request this ? so far 31% complete and we are into hrs here.
It insists on opening albums in album order and not oldest first, this has to be set manually each time I open, are there no settings one can preset ?
All in all a very questionable upgrade, until you get to the editor where you certainly see the new functionality, but first I would like to get the basics sorted out.
