I have an iMac 2019 with macOS Catalina, 16 GB, 2400MHz, Grapichs Radeon Pro 555X 2 GB. It used to work very fast with the version before this one. This two days since the actualization it's been horribly slow (only Lightroom) What can I do? Thanks

Check to be sure the settings regarding the use of the Graphics Processor are set the way they were before.


Check to make sure face detection is turned off. Check to make sure Sync with Lightroom Mobile is turned off. Check to make sure address lookup is turned off. When I say "check", I do not mean that you should state that you never use these features. I mean visually check the settings to make sure they haven't been accidentally turned on somehow.


And provide some more information please ... horribly slow performing what actions? Please be specific.

Thank you! 

As soon as I turn on Lightroom everything I try to do is slow, even changing from one pinture to the next. I don't do much to my photos, only the basics (exposure, contrast, hsl)

Thank you! I'm not sure if I have any plug-ins... I use Lightroom for the very basic and I've never installed anything extra. All this happened two days ago, after the actualization

I've got this same issue, but with a Mac Pro 2010, 2x3.46 6-core, 1 TB Evo SSD, 28GB RAM, Radeon RX 580 8GB.
I've tried all the usual things, optimize, turn off syncing (address, face, cloud), increase cache size, purge cache, disable/enable GPU acceleration. No plug-ins.

Update: I've uninstalled and reinstalled LR Classic, still the same. I came across this article and noticed the bit about screen resolution (I have a 4K 27" monitor but set it to 2560x1440), and when LR is full size it's very slow, but when I resize the LR window to half size or smaller, it speeds up drastically, but I can't use half of the screen to view/edit photos.
I also built 1:1 previews and it helped a little.

Same here. macOS Mojave, MacMini 2020, i7, 32GB mem. I see it as being back to LR5/6 performance.

It looks like it's regenerating the thumbnails when browsing in the library module, and so forth. It looks like a very buggy release - but adobe is used to thouse.
