If you have experienced a massive slow-down and / or crashes after upgrading to Lightroom 6.2 or 6.2.1, basically the versions with the new and improved (BOOOOOOHHHHHHH!!!!! Shame on you, Adobe!) “Import” window, you have two options.
You can roll back to a previous version of Lightroom. This entails uninstalling Lightroom completely and then re-install a previous version (extracted from a backup or downloaded from the Adobe website). You can find detailed instructions on the Adobe website here:
You can just disable two of the new features, notably the new “Import” window (have I already said this? BOOOOOOHHH!) and the graphic card processing, restart the program, and Lightroom should start running fast again.
In detail you will have to disable:
– in Lightroom “Preferences” > “General” uncheck “Show ‘add photos’ window” (not sure about the exact name in English given my copy of LR is in Italian, but it’s the 2nd checkbox in the “Importing options” section
– in Lightroom “Preferences” > “Performance” (the 6th tab) uncheck “Use graphical processor”
– restart Lightroom
Instead of reinstalling the program I went with this second option, and luckily it worked like a charm. Now if only Adobe started properly testing their updates before releasing them we would be all really glad…
