Lightroom Classic 12.3 slow?

Is anyone else suffering from slow performance since the release of 12.3?

I edit several hundred photos in Lightroom every day. My newer (i.e. six month) high-end computer is lagging with this version of Lightroom. It was zippy with previous versions. Everything else runs quickly on the computer, so I suspect that something with the latest version of Lightroom is the culprit.

Has anyone else who was having slow-down issues with LrC 12.3 upgraded to 12.5 yet? Wondering if with the newest version the issue is a non-issue?

My busy season was in full swing and I didn't have time to troubleshoot the issues, so I stuck to 12.2.1

I did what Rikk Flohr suggested (look at the previous comment) and it
worked.

Anyway, it does seem that LR doesn't manage the use of GPU memory well.
After editing about 50 images it starts to slow down and I just restart the
software and it gets better.

That's good to hear. I'll try upgrading to 12.5 once I have more time.

As for slow downs after editing ~50 images, I haven't seen that. I regularly edit 500-700 images per day and don't see slow downs after a certain number of images like you're describing -- only the overall slow down that I've described in this thread. I suspect something else is happening with your system to cause that.

Feels like the 12.4 update didn't fix this issue. What do you think?

That's disappointing to hear.

I haven't had time to try 12.4. I'm in the middle of my busy season, regularly putting in 12+ hour days. So I'm not exactly feeling compelled to be frustrated by lost productivity again.

Update. I did uninstall and installed 12.4 again and now it seems to be fine. There is still a little lag maybe because I use a midi controller.

Another thing I've noticed is that after editing about 50 raw photos the performance starts worsening. I just close and open the software and it gets better (maybe purge cache?).

Just for reference I have a i9 13900, 64GB DDR5, RTX 2060 6GB and a M.2 drive.

Also, I had to go back a version on Photoshop beta because photos from Lightroom weren't opening in Photoshop.

I have exactly the same issues in Develop Mode.

Infuriating.

What version of Lightroom are you on?

I've stayed on LR 12.2.1 because of this issue with 12.3. I'm in the middle of my busy season and I don't have time to mess with later versions that slow down my workflow.

Try increasing the cache setting and purging it, worked for me at least

I've done that plenty. That has not helped.

One common cause of "Lightroom X.x was working great but when I installed Lightroom X.x+1 it was slow but when I revert to X.x it speeds up again" is a bad install. When there are nebulous, vague or not-widespread complaints of slowness it is good to rule out the install itself.

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

If speed doesn't improve after this procedure, reset preferences

This procedure works for both Lightroom Classic and Lightroom Desktop. If you are using Lightroom Desktop it can change the location of your local storage. Please review this setting after resetting preferences.

Reset Procedure:

1. Close Lightroom.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

3. Overwrite the Preferences when prompted by the dialog.

4. Close Lightroom.

5. Restart Lightroom.

Those two steps will usually weed out the bad installation as a cause.

If after carefully completing those steps you still perceive slowness, it is time to provide very specific information about the nature of the slowness.

I can confirm I uninstalled and reinstalled once with the Adobe cleanup tool, then reset preferences, and Lightroom was behaving slow as previously.

However, I did one more uninstall and reinstall of Lightroom alone as you stated, and now it seems to work very well.

Very strange behaviour and I only put 1-2 hours on the new install so let's see if it holds up! This shouldn't really be necessary but at least I can work well again 🙂

Same issue for me. Lightroom was blazing fast up until the previous update, now it takes 2 to 3 seconds to load every image in the editing panel, a lag not suitable for big volume editing.

That's exactly the type of behavior that I was seeing as well.
I've downgraded to 12.2.1 and everything is fast again.

Unfortunately I'm using the new Nikon z8 which is not compatible with 12.2.1, so I have no options. editing with smart previews is viable, I'm using that for the time being, but I often need to zoom so I'm back at the start.

Hope to see a fix very soon.

Well, I downgraded to LR 12.2.1 and the previous speed is back. This points to something about 12.3 being problematic on my machine.

I also noticed that with 12.3, you have to click an image in the filmstrip, you have to click the image itself rather than anywhere with that cell. That was a real nuisance.

Yes!! 12.3 is way slower on my computer (Mac Studio 2022, Apple M1 Ultra, 128 GB RAM). I had to downgrade to 12.2.1 a few times now because 12.3 is just not usable.

FrostyOfTheNorthAuthor

Known Participant

It not much consolation knowing that it's not just me, but it helps.

It was a good suggestion to downgrade to 12.2.1. I just downgraded to that version and now Lightroom is running at the previous speed again. Something about 12.3 is unusably slow when dealing with a volume workflow. It's very interesting that you're seeing the same slowness with the Mac version that I'm seeing on the PC version.

Lagging during what actions? Please be specific and detailed. Please post your system information as shown in Help->System Info.

In the develop module is where I notice it. Moving from photo to photo, applying radial fills -- pretty much every editing step is laggy compared to before. It's tough to evaluate objectively, but in general Lightroom used to keep up to me. Now it doesn't and it's painful.

My OS and Dell-supplied drivers are up to date. I was using Nvidia driver 531.41 but based on this thread about slow performance, I just downgraded the Nvidia driver to 516.94. It seems better, but still slow.
