Lightroom Classic running slower with 13.3.1 Update

Report · Jun 17, 2024

Hello Adobe team and users,

Is anyone else experience longer load times, and lagging when using many of the develop module tools after having installed the latest 13.3.1 update which included the Generative AI tool in Remove, and the Lens Blur feature?

I have noticed several distinct areas of the program running slower, some of which include scrolling between photos in the develop filmstrip can sometimes take 5-10 seconds or more to transition between photos. Sliders for almost all tools can be moved freely, but sometimes the results are not reflected in the photo until a few seconds have passed, which used to show instant change reflective of the element being adjusted.

Most notably, when using the remove tool without Generative AI box checked, it is INCREDIBLY slow compared to before. The rainbow pinwheel pops up with every third click of the tool, and often takes two or three seconds each time to generate and become available again. This tool has often lagged, but typically not to this extent. I was told by the last moderater to past this information below for reference, in case it helps solve any of my issues.

Same issue on Windows.

After update LR is extremely slow, impossible to use. Literally any operation lags. Switching tabs, applying presets, scrolling through catalogue, etc.

Yes. I am really pissed off! I am a long time LR Classic user running LR Classic on a Mac Mini with Sonoma 14.5. I have optimized, emptied cache, changed the cache location to a super fast drive and not getting any improvement. Sadly going back to the previous version is a lot of work, so I am just waiting for Adobe to admit the problem and fix it in an upgrade. I wouldn't hold your breath for them to do it, so if anyone has a work around or has gone back to the previous version, I'd love to know about it!
