Hi there,

We're sorry about the slowness that you see in Lightroom Classic. We're here to help.

Did you notice this issue after the latest update? Where are the images located? What are the file sizes that you are working on?

This issue can happen commonly because of these two factors

1)Bad Install

2)Corrupt Preference File

Try this method to re-install once:

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 and wait for 5 minutes.

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the 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.

Let us know if this helps.

Thanks.

Thanks. It's magically working today. I am totally baffled. No reboot. LR still running from yesterday. I just picked up with my edits where I left off and the problem is gone. I will make note of the restart procedure if it happens again.

Hi there,

Thanks for reaching out. I’ll need more information so that I can help you with this issue.

Could you please share the location of the original/source images? Are they on the internal drive or an external drive? Are you using Solid State Drives (SSD) or HDD? Does this happen when editing images with a specific set or collection? Where is the catalog stored? Is it on an internal drive or an external drive?

Are you using multiple monitors? Does this behavior appear after a series of steps or in any screen mode like fullscreen?

Do you use any other resource-intensive application that might be behaving oddly?

To begin with, please go to Lightroom > Preferences > Performance > Use Graphics Processor > Set it to Off if it is on Custom or Auto. If this shows you any differences, please check this article to troubleshoot further: https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html

We hope to hear from you soon,

Thanks!
