LrC 10.2 performance lost in Library Dashboard

[Mrs.Aquarelia]

Hello, Dear community. I'm using Mac Book Pro 16'' 2020 with top hardware.

In earlisr version I observe a great performance while change Exposition and other settings to a selected set of photos. Now after LrC 10.2 update while I'm changeing exposure settings for a set of selected photos I have seen a great performance decrease.

Have you observed such a problems after upgrade?

Try turning off 'Use GPU processor' in your preferences and see if that makes a difference when you batch edit exposure.
