LR Classic 12.1 slow performance

Since Lightroom Classic updated to 12.1 in December, the performance of my system while in LR Library and Develop modules is extremely laggy (to the point I want to throw my laptop against the wall). I run on Windows 10; LR Classic 12.1 Build 202212072312-d7ab524b. Back in early December when I first noticed the poor performance while in LR, it was causing "paging" on my laptop memory (and caused my system to just shut off or blue screen). Knowing that LR updates lately have been pretty heavy/fat in terms of workload with all the new AU, I decided to upgrade my physical memory from 16gb to 32gb (max my Dell XPS laptop will accept) and upgraded my 500gb SSD to a 1tb SSD. Still performs slow/laggy even after those physical upgrades. Takes my mouse or Wacom pen too long to get a response when masking or dragging cropping handles, for example. I can barely get through edits for 1-2 images within a 30 minute timeframe. Un-exceptable.

Today...thinking slowness was due to outdated drivers for my NVIDIA graphics card, I updated it as well. Only very slight improvement...barely noticeable.

As a high volume sports photographer, the last project I photographed was just a week ago. I should be so much farther into the completion of this project than I am today.

Any suggestions are appreciated. Would LOVE for Adobe to release a bug fix/update. This was NOT an issue at all before December 2022!!!!

I was using the patch tool in LR Classic when it got very slow, so I went to the Task Manager and quit it. When I restarted LR, and resumed working on the spot removal, it got very slow, so I went back to the Taask Manager to stop it and then restart it. But, while it is on my left screen (see the screen capture attached), Task Manager doesn't even know it's running!

Further information: I stopped LR using the X in the corner. I restarted it. Then it shows on the Task Manager. In develop I used my Wacom pen to zoom in to the area to find spots. Then I selected the patch tool and Lightroom immediately disappeared from the Task Manager Apps list!

I am having the same issues. I am running a brand new install of Lightroom and it is just laggy. And if I decide to use the AI funcitioin, I have to restart LR in order to get it to work again. It is so slow that it makes it unusable. Previous release was working perfectly well. Now my Core-i7 is just at 100% load without doing anything. I have 10+ GB of free RAM, GPU is only 30% loaded when I do something, SSD is bearly used.

Please expand on that, were you getting a Windows OS notification/error about the paging file?

Where do you keep the Windows paging file (by default C drive) and how large do you allow it to get?

Where do you keep the Camera RAW CACHE for LrC, and how large do you allow it to get?

I was receiving Memory_Management errors when it would blue screen. Took to my computer service guy and he confirmed memory issues in the Pagefile.sys (as I suspected). Knowing how much more has been added to Lightroom with all the new AI, I detemined upgrading my physical memory and internal SSD was the best course of action. But despite that, I still had performance issue while in Lightroom.

As I included in my post yesterday, I upgraded my NVIDIA graphics card drivers (were out of date). Still not where I wanted the LR performance to be after updating the NVIDIA drivers. Then late yesterday I found newer drivers for my Intel Graphics driver and updated those as well. Following the combination of both of those updates, I feel that the performance is noticebly better (not perfect...but better). Updating both NVIDIA and Intel graphics drivers seems to have helped.

Some notes on reverting versions to improve performance.

Often on the forums, I see reports of people saying something like:

"I upgraded from version X to version Y and version Y is very slow. I reverted to version X and the performance returned to normal."

On the surface that seems to say version Y has an issue and that reverting to version X restore functionality. Also likely is that the installation of version Y was flawed but not the application itself. Often a clean reinstallation of version Y solves the problem just as reverting would.

Clean Lightroom Install Procedure

Close Lightroom

Restart the computer

Use the Adobe Creative Cloud App to uninstall Lightroom

Restart the computer

Install Lightroom via the Creative Cloud App without launching any other programs.

Restart the computer

Launch Lightroom

Wait 5 minutes

When considering reverting to a previous version I would recommend trying the clean install procedure first. This process insures the current state of your machine is clean. After days, weeks, or even months (I've never found a machine that was years on the current session) without restarting, considerable cruft can accumulate and cause some funky behavior.

If you've reverted, I would recommend giving the clean install process a try to see if we can get you acceptable performance and the latest fixes and features.

So a WACOM, what drivers, specifically driver dates? Have you checked?

Wacom not the source of the issue. Ran an check for updates and my Wacom is current.
