Lightroom Classic 13.0 running REALLY slow on M1 Max with 64GB RAM.

[Junction10Photo]

I'm running a Macbook Pro 16" M1 Max (24 core GPU) with 64GB RAM.

After updating to Lightroom Classic 13.0 - it's running REALLY slow - pasting settings from "Previous" for example, the pop-up window says "Estimated time: 1.0 seconds" but it actually takes between 2-5 seconds.

Hovering over develop presets takes in excess of 10 seconds to change the preview of the main image.

Moving between images in the filmstrip has become tediously slow...

The last build of 12.x ran much faster...

Hopefully it's something that'll be fixed in an update - is it running slow for anyone else?

[good_Captain1587]

Has anyone got around the slow issue, please? Wedding season is about to start, and lots of editing and speed is a game changer. It is so slow; you click, and there is a delay. The healing tool is like a turtle. Does anyone have any advice?

Still a major problem... 13.3 on my spec'd up Macbook M1 Pro is terrible... switching through photos is painfull...  1 - 2 second delay, really bad! Used to be instant... All the GPU performance settings are still on... come on Adobe, what's going on...

[Ian Lyons]

I recommenend that you start a new thread and describe how LrC beahaves in the module your working in, etc. Doing so will avoid confusing the issues that affected earlier versions with those that may be the outworking of the new preview architecture in the Library module and Develop module pre-fetch and caching behaviour.

[Le Grand Jour]

Yes, I have exactly the same problem. Version 1.3.3 is painfully slow; switching between images in developer mode requires !!!100%!!! CPU usage. A simple zoom takes 3-4 seconds on a Mac Studio Ultra with 64 GB of RAM. Actions that used to happen instantly upon clicking the button now take several seconds. This is a very bad direction... my work is significantly slowed down; with 3000 images, the several-second delays extend my work by hours.

@Le Grand Jour 

I have a Studio M1 Ultra with 64GB of memory and don't experience the issue you describe. With 13.3.x, LrC uses the GPU to pre fetch and fully render images in the Develop module. This should, and my case does improve the image load time in the Develop module. If you're seeing maxed out CPU, then I recommend that you check whether GPU is configured for full acceleration as shown in attached screenshot.

same. not so slow, but much slower than previous version, specially during export

Same here, since 12.X all the version are really really slow on export, on a fresh install of Sonoma 14.5 on M1 Pro... we are talking about 3X or more, slower compared to 12.X

Your built-in memory is only 8 GB. While that is still within the minimum specs, it is really the absolute bare minimum. At the same time you have quite a few third party plugins. I'm not sure if that would help, but with such hardware I would disable all these plugins to see if that makes a difference.
