Hello, I've seen this problem posted on several forums going back a few years with little resolve. After creating a mask on a photo and after so many edits to the mask, the program begins to lag and freeze so badly that it becomes unusable. 10-30 seconds for each mouse click to register. Click-and-drag functions, like using a mask brush, stop registering entirely.
I’m running on Windows 11 PC. My primary catalog and photos are saved on an internal SSD. Backup is on an external SSD. My computer is about 1 year old (see SYSTEM INFO below.) The problem is with Lightroom Classic only, all other software and OS otherwise run perfectly. This problem occurs with all image types, RAW or JPG. Catalog is backed up/optimized/integrity tested multiple times per week.
Here’s what I’ve tried:
- Disable GPU acceleration in LRC (no difference.)
- Update NVidia drivers.
- Switch between Studio and Game Ready Nvidia drivers.
- Run chkdsk from cmd prompt on all drives.
- Lower desktop resolution.
- Delete Previews.lrdata folder.
- Delete Camera Raw GPU Config.txt in Users/AppData/Adobe/CameraRaw/GPU/Adobe Photoshop Lightroom Classic.
- Switch between the different image preview types (Smart, 1:1)
- Purge RAW cache.
- Check RAM usage - LRC is using under 10% of memory when idle and under 50% when the lag spikes occur while trying to edit masks. I never saw it surpass 50%.
- Check GPU/CPU heat monitors (nominal.)
- Uninstall LRC, wipe preferences, re-install and re-import the catalog.
None of these fixes made any noticeable difference. I might be forgetting something but I've tried everything I could find mentioned in forums. Seems like the only fix that has actually helped anyone with this issue is a few people realized they had faulty harddrives after running chkdsk. The only thing I haven't tried is fully wiping and resetting my system, because the problem is only with LRC. Wiping my entire system every time Lightroom breaks is not a viable solution. Thanks in advance for any help.
