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.

Same issue for me. MacBook Pro 2018 macOS Catalina, 16 GB. It used to worke fine with Lightroom classic 9.4. Since update to LRC 10.0 the whole process is very slow. Scrolling through pictures is horrible. No Plugins. I already checked sttings for GPU accelleration (turned on, off, automatic), but that doesn't seem to make any difference.

One quick follow-up... changing the color profile on the mac display (system settings/disply/colors) to Apple RGB will leasd to an increase of the performace. So it seems to be related to the slected profile of the used monitor. Switching back to the default profile settings, will slow the performace down immediately. Hope this information will help to solve the problem.

Great hint! That's exactly what I was looking for.

The LR 10 Classic Update was unbelievable slow in grid view (Mac Pro 5,1 / 48 GB RAM / NVMe / macOs 10.14.6 / Radeon RX 580 8 GB). After changing the Colour profile from my monitor to sRGB it was like 10x faster(!)

Btw: The Developement feels quicker and faster with this update, good job on this one.

Hopefully the colour profile bug will be fixed soon ...

After upgrading to LrC 10.1.1 and recalibrating the monitors with i1Profiler v3.3.0, the same issue of unresponsive interface happens. The only way of out is to force a reboot of the computer!
