Very helpful to keep these tips updated as time goes on and LR Classic is updated - thanks!

Wow. This is gold. Wisdom on which settings and expectations you should adjust. You just saved me from buying a new computer. THANK YOU😊

Another very helpful video, Matt. Thanks so much!

ALOHA MATT. this was good. im here just havin trouble with mine. so yes im glad i found u! SOLID WORK !

Thanks Matt for the tips! Some of these I didn't know that might be helpful later. I specifically built my PC to run Lightroom 😅- Did tons of research and found the components the operate the best with Lightroom haha and you know what, I haven't had any issues with it. The biggest difference for me was having an NVMe drive. I store my catalog and the previews on there, I render 1:1 previews for all my images. It doesn't take much time because they are being stored on the NVMe drive, import process is a LITTLE slower, but just grab a cup of a coffee :) Graphic cards are one of the biggest things for Lightroom I think. Running LR on a slow intergrated graphics really bottlenecks it.

great tips Matt. Keep it up

Catalog optimizing helped me a lot... Thank you! 🙂

Excellent!

Why would anyone be ugly to Matt?! (Shame on them! )....... I was using a business class machine and struggling with Lightroom performance. I swapped to a higher-end windows machine with a good dedicated graphics card, turned off syncing and it was like the dawn of a new age. I rarely get any slow down, even when processing 54 MB to 120 MB raw files. To save on cost, I purchased a "last year's" model of a gaming laptop for a great price and it was worth every penny. I swapped to dedicated external hard drives (backed up) to help me organize my files, save on storage fees and eliminate sync/upload times. I had tried all the possible adjustments recommended on both the old machine and now the new one, and changing machines was the only thing that made a significant difference. You recommend this up front, and in my experience, it is makes post processing so much more enjoyable!

Since the spot healing, masking, and sharpening/noise reduction slow things down the most I do them last. That way I can do everything else while it's running fast.

Good video Matt. Picked up some things and even clicked on the more performance tips and find that I'm at min ram to run LR and PS at same time. So now I know to close PS when not using until next upgrade. have a question on Video cache Settings in performance section that I didn't see in the Adobe pages. Is max cace size ok a the 3gb default? I take some movies with my camera and store the files in the same files as the photos. Just easy to keep together. Pretty sure you've said you don't mess with these but maybe someone has a an idea? thanks

I'm about to get a new PC and your video convinced me to get the Adobe recommended system requirements instead of the minimum I have now. It's worth the added cost. Thanks.

One mystery I have is that LrC loads very quickly, but despite every screen working perfectly, there is a delay of about 1-2 minutes before the Develop tab has any previews or functionality in the right hand panel. I can load LrC and do an import and see all the images in the library but there is a sizeable delay in the Develop tab being available - not sure if anyone else gets this?

Thank you Matt for this, also I would to ask if you were the one that had a session on how to remove menu items in PS that were barely ever used to clean it up and not have all those unused items and where would I find it??

Thanks. More to do with backup write speed, Is there a quick way to clear develop histories and large previews Etc. To reduce catalog & it’s data file sizes

Thanks Matt. With the increasing power of LR there are fewer reasons to ever go into PS. So it is frustrating that Adobe do not allow users to set a specific drive for caching/scratch work like you can in PS. Even though I have over 20% space on my primary drive, panos, masks etc take way over that and LR then always defaults to using my slow spinning disk, which results in crashes, when I want it to use a faster attached SSD. Unless I am missing something, I think Adobe needs to improve this.

Thank you so much for this Matt! It helped out tons! One question though. If you have a lot of presets installed does hiding them improve performance?

Any way to specifically speed up the time to switch between photos in the Develop module?

On my version of LR it doesnt have that cloud icon to the right of the WEB option. And every other time i have to manualy go into adobe settings to change back to 25% speed as theres no way to stop uploading the back up. im running on a 2012 mac mini i7 with 16 gb ram and shooting with a 18mp camera on med raw and it will still bog down with the spinning pinwheel. Would disconnecting the internet help?

Great tips, Matt. BUT on my Mac Studio Ultra Adobe Lightroom now screams through photos!

I think I've got a single preset pack installed but I did have to kill about twenty tabs in my browser to get your video and Lightroom to play nice. 🤣 Good tip on the cache I've stepped that up to 20GB, in theory I did lose a little speed when I moved the catalog off my primary M.2 to a slightly slower but significantly larger M.2. My PC is getting old but is purpose built and easily upgradable, I need to move the music (on drive E: "Eugene") to an SSD.

As always, very useful Matt. One question - if I forget to select embedded & sidecar when importing is there a way to change the files in the library or would I have to start again? That, of course, is a pain when you've started to work on most of them...

I didn't know that you could sync files using the cloud in lightroom classic!

Excellent. Thank you

The Problem I'm facing is that after some time LR gets slow even know my PC is running at 25% RAM usage. To me it looks more like Lightroom slows itself down

I’ve always been frustrated with embedded previews because for some reason they will not reliably show focus/sharpness at 1:1. On most photos it seems to work just like photomechanic but then sometimes I zoom in to check focus and the shot looks soft. However if I then switch to the develop module I can see that it’s actually tack sharp. This bug is very frustrating and it’s been present ever since embedded previews were first introduced years ago.

under preference it is off how to set to auto ???

Did you forget to enable editing of smart previews? My RAW files are on external drives and smart previews allows me to edit those files very quickly.

Question: I don’t have the xmp option on, but I do use other programs like the Tpaz suite, Photoshop, and Silver Effects Pro. Should I turn that xmp option on?

Is there a way to reduce the size of the Lightroom Catalog? I am a hobbyist and only have one catalog for photos and it is getting quite large. I have never optimized my catalog, but plan to do it immediately.

Hi Matt! I know this is not something you support, but I'm hoping someone else out there has experienced and solved the problem. I purchase an M1 MacBook Pro the first of the year and love it except all my external hard drives will spin down if not accessed for about 20-30 seconds. They don't disconnect, just spin down. As soon as the computer needs to access a file, they spin back up which slows down productivity since I store all my photos on an external hard drive. Apple support has been no help and won't acknowledge the problem. All my external hard drives work perfectly on my older desktop Mac. There are some KZfaq videos of others experiencing the problem and they suggest going into Terminal mode and changing the Disksleep setting, but I am a little concerned about that. I do have all the other battery and performance settings correctly set according to Apple. If anyone has any suggestions I would certainly appreciate them. Thanks Matt for another great video!!!

Lightroom classic 13 has been a disaster. Running so slow. I wish it would be possible to downgrade the catalog to 12. Many have problems with LRC 13. Any updates on sluggishness?

My photoshop keeps crashing and shutting off and idk why. It’s the latest updated version. Could it be too many plugins?

Library Module: disable Histogram on RHS panel also speeds up reviewing....

I got a question, I got a Sony A1 and once I import my pictures to Lightroom, the quality of pictures aren’t the same, no sharp and with noises, maybe I’m doing wrong with the camera settings? I normally shoot in RAW Thank you

LrC uses few threads and almost 0 of your GPU.

You skipped explaining the preview 1:1 option. I’ll have to google it.

So important to write xmp files! When transferring my catalog to a new computer something happened to it and also to the backup. This resulted in needing to create a new catalog from scratch which would have been impossible without the xmp files. LEAVE IT TURNED OFF AT YOUR OWN RISK!!!

Long comment, your wrong. Lol lol lol. Just joking.

What Lr slows down the most is the size of your catalog, try a catalog with fewer photos and you will see how quickly everything works.

The only thing that slow its luminar AI..
