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

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?

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

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.

are you guys still having the same issues? i just started a LRC/PS sub and it's pretty slow moving between photos and general program flow. but i do not have any recent history to compare against with LRC. i'm running an m1 pro macbook. my capture one was much faster/ responsive in general program flow.

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...

My LR instance updated to 13.0.2 the other day and I'm seeing considerable performance issues as well. General overall slowness, and specifically when moving between images in the develop module via the left/right arrows on my keyboard through the grid on my second screen, there's significant delay. I'm on a brand new system too (Win 11 Pro [23H2], 13th Gen Intel Core i9-13K, 64 GB RAM, 8 GB video, & 4 GB NAND NVME SSD).

Yeah I'm on 13.0.2, on a fast machine, and having the same issue ... very slow jumping between photos in develop module. Seems like a perennial problem with Lightroom, I wish they would fix this stuff before shipping. It's really hard to work when you have to wait a second or two every time you want to make a little crop or edit.

A friend of mine was having similar issues on her new Mac Studio especially after doing some adjustments in the Develop module. Updating to LrC 13.1 helped a lot with that issue.

I can confirm this as well, 13.0.1 is painfully slow especially the development module that it's really unusable.

I am also getting the color corrections not being applied for a few seconds in develop, general slowness across all modules, and export only uses 60-70% of CPU (used to peg every core on 12.x), so that's 40% slower.

I say if Adobe is going to waste my time by making me wait 40% longer for files to export just because they are a billion dollar corporation that can't even code their own software to be at least as slow as the last version, I should get a 40% discount on my CC subscription please.

Really wish I could go back to 12.5 but have shot a few hundred photos so far on 13 so going to be a challenge... Wish there was a way to revert the catalog until this terrible update gets fixed....

Export now uses the GPU instead of the CPU so it is normal to see below 100% CPU utilization. It should overall be faster than the old CPU based export. Note that there is a bug in LR 13 that even if you disable the use of the GPU for export it still uses the GPU. You can't say that it is 40% slower if you don't actually measure the export times and compare. Others have shown that the GPU export is quite a bit faster on Apple Silicon than CPU based export.

Strange! I have a 16" M1 Max with 32 GB and it is as fast as ever. Certainly no real difference with v12 that I have noticed. Most of my images are from a 45 MP camera so no cheating with small images either.

Do you notice ANY slowing in develop mode? Mine is going very slow switching photos, and I'm on an M2 Mac Studio ... it's blazing fast otherwise. Curious what your catalog settings are .... specifically these "File Handling" settings?

Not really. The switching photos is actually supposed to be one thing that was fixed recently by having Lightroom Classic prefetch the images you're likely to load next. It's basically instantaneous for me if the image folder I am in is on my SSD and a bit slower if they are on my NAS server but still perfectly usable and actually really fast (due to the prefetching) when I have worked on an image for a while before switching to the next.

Your preview settings seem very low resolution to me but they also should not have any effect on walkthrough in the develop module as develop does not use any previews, it just fetches the raw file and renders from that. 1:1 previews are usually pretty useless and actually in general slow things down. They are again only used in the Library module, so you really only need those if your workflow relies on zooming into 1:1 in Library. If you don't do that normally, do not generate them and definitely don't keep them around. Do make sure that your standard preview size is at least big enough to display on your main display otherwise Lightroom Classic will be constantly regenerating the standard preview so in general you really want to use auto there as a setting, which should automatically be set to be good for your main display's resolution. 1680 pixels is almost certainly far too small as that is not even enough for a very low resolution 1080p screen which is 1920 pixels wide. Below are mine.

Noticed exactly the same, as soon as LR Classic updated to 13.0 (on Macbook Pro with M1 Pro).

- switching between photos that already have colour edits applied, they appear 'unedited' for a few seconds, before the correct colours appear

- it seems much slower if I've got AI masks applied (hair, body skin etc)

- exporting images seems to take twice as long, and I hear two notification sounds when it's complete.

After updating LR 13, I later updated to MacOS 14 Sonoma, and it's not made any difference.

Looks like they probably added some new functionality in LR 13, but very unoptimized, and hoping an update will fix it - as long as Adobe know about it.

LRC 13.0.1 + Ventura 13.6 on M2, glacially slow to upload photographs.

Just over the LRC 12 no preview bug and now a plummet in productivity to upload images.

It wasn't like this on LRC 12.

To Preview I'm seeing 3 images display per second.

For some reason images that have already been uploaded from the card are displaying again looking like they've not been uploaded, so it's even more inefficient. Wondering if renaming the destination folder has done this.

Have restarted.

I'm seeing better performance with LRC 13.2 after upgrading to the latest Sonoma (from Ventura).

Still seeing that images on the same card loaded either from the camera via cable or via a card reader are not regarded as the same image. So the same images look like new images to import. I would have thought they are duplicates.

Running 13.2 on Sonoma on M1 Max Macbook Pro, I literally was waiting for literally 30 seconds of beach ball on every clone stamp use today cleaning up a wall!

Same experience here. Unbearably slow performance in v13.
