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?

Have you tried closing LrC, then restarting?

 

Apparently their may be a install oddity with LrC, where some AI bits get installed during a second install (i.e. at a restart) (would expect a pop up stating that however)

I have, but no difference.

 

I'll try downgrading and upgrading again tomorrow and see if a reinstall fixes it.

Yup. Same. 13 is Easily the slowest release I've ever tried in my MacBook Pro M1 Max. The lens blur feature is nearly unusable taking 5-6 seconds to render. Develop module editing is slower than ever. Sad...sad...sad

By @Eric11000z

 

Slow Lens Blur is totally expected, because it’s labeled Early Access, basically an un-optimized beta. Lens Blur runs much slower than anything else in the app right now.

 

But everything else is sufficiently fast on my MacBook Pro M1 Pro. It’s a mystery why some Mac systems are fine and others seem slow.

For those having issues, what is Activity Monitor reporting in terms of CPU and Memory?

What version of MacOS? I have the same computer (except 32 GB RAM) running MacOS Ventura 13.6 and Lightroom Classic 13.0 and I do not see this at all. Lightroom does not even say anything about an estimated time when I do 'Paste Settings from Previous', because it is almost instantaneous. Same for hovering presets, which is also very fast (only adaptive presets take a little more time, but that is to be expected).

 

@Eric11000z Lens Blur needs some time to generate the AI-based depth map, so that is to be expected.

Same experience here. Unbearably slow performance in v13.

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!

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.

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.

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.

I re-installed LRCC again today to try and fix this issue, did not help even one bit. Still definitely slower than 12.5 still, can we please have the option to just use all available CPU and GPU to export as fast as possible!?

 

Checkbox makes no difference, both CPU and GPU are ramping up and down like it's throttling, but temp is around 130F, when using DNG converter it maxes out all the cores and actaully heats up to 200+F!

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.

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?
