(Windows) Takes 1 Minute or more to move between images

I created a new catalogue, cleared the cache, set GPU usage to auto. Nothing. As soon as I start working on a picture, the memory used goes to 10 gb and lightroom slows so much it is unusable. Adobe what is going on?!?!?!

Same issue, has anyone got a response or help from support on this or has it just been silent??? I have another thread going and don't see any replies from staff or support.

Had the same issues. Specifically, I noticed that LRc was working sor of ok, until I applied a mask to one of the images. Then everything, for all the images in any folder, develop or library module starting to work horrendously slow. Updated Windows (10), updated GPU driver (3060), nothing worked.

Then I removed all the plug-ins (I'm not using any anyways). And now the LrC it's working fine.

Hope it helps.

Add my system to this list of slow LrC 13.3.1 users: Mac Mini M2 running Sonoma 14.5.

Accessing menu commands, clicking on the next image in the Develop module, adjusting crop dimensions, and updating keywords, so far are painfully slow operations compared to previous LrC versions.

Added: Activity monitor data:

when LrC is processing a Develop module image switch, Acitivty Monitor shows LrC at 325% CPU and Memory usage at 7.87 GB. After the Develop module opens the clicked image (in about 10 sec) the %CPU drops to about 40% used by LrC with the next highest being WindowServer and kernal_task, both in the low 20% usage range.

Updated to 13.3.1 - For reference I have just over 800k images in my catalog.  The update prvovided speed improvements, BUT (it's a big but) I can not rate, flag, apply user presets to edits, export files, batch process files, raname files...plus whatever else is not working.  In other words it's still a mess.  My sync issue will have to wait.  I need to be able to deliver edited images first. 

Updated to Lrc Classic 13.3.1
The performance issue seems to be resolved but I only did a quick check for now.
I've tested switching back and forth from Grid to Develop in varoius folders that were extremely slow in the previous version. Switching from modes and between photos is faster than recently. I'll confirm after I'll have a chance to work a bit longer.

I am experiencing the same performance degradation on 13.3. I didn't see those on 13.2. As described by other users above, even switching between photos can take 4-5 seconds or even longer. But sometimes it happens quickly.  I have shut down syncing to the cloud and also shut down writing of metadata to .xmp and jpg, etc. Please issue a fix to this as soon as possible. Thanks

Couple follow-ups:

1. I rolled back to 13.2. (Lost a few catalog/metadata updates, but fortunately hadn't done a lot since upgrading.) So far performance seems fine as it was before the catastrophic 13.3.

2. From a few other forums & feedbacks I've seen, this could be correlated to LARGER catalog sizes. (Hint: Adobe - do real-world size/scale regression testing.)

I work in SW, and specifically in data/database related for most of my career. This could be, and is consistent with, something about their larger Catalog changes that missed some key performance aspects - like a database index or a newly non-optimal query. Tons of operations would relate to querying the catalog, and all of those seem painfully slow.

(That doesn't seem to explain all of it, but I wonder if could be related. Just in case any Adobe sw-eng folks read these.)

same here. Extremely slow and working with fully updated drivers. Had to roll back to 13.2 because is was unworkable.

having similar issues with my iMac (Intel / 40GB Ram) when trying to pick/reject images and moving images between collections. LR is very laggy & had to wait several images for it to respond. No issue with LRc 13.2.
