Lightroom Classic: (Mac) User Interface slow after upgrading

Hello,

Since upgrading to Lightroom Classic v10.0, all UI-related functionality is painfully slow. All editing functions are working correctly and quickly but scrolling through the catalogue or even scrolling a side panel is taking many long seconds to refresh. Unreasonably long.

Disabling GPU Accellaration has no affect on my Lightroom's performance.

macOS Mojave 10.14.6

Mac Pro (Late 2013)

3 GHz 8-Core Intel Xeon E5

32 GB 1866 MHz DDR3

AMD FirePro D700 6 GB

I'm another person with a 2017 MacBook Pro who upgraded to V10 only to find the UI slow and the Adjustment brush so slow as to be unusable. 

With a course to teach tomorrow I had to abandon V10 and went back to V9.4 where everything worked perfectly.  I'm running 10.15.6 but as others have said, this release runs perfectly and the path back to 9.4 was painless!

The only other item that this thread makes me think of is that I have two monitors (laptop screen and a BENQ Sw271) although they are used in duplicate mode rather than in extend mode (problems with Zoom otherwise!). Also that both monitors are custom calibrated with an X-Rite I!Pro.

Finally, could Thunderbolt be a common thread here with V10 (external drives, external monitors etc).

I run a 5.1 MacPro with no Thunderbolt. Thunderbolt is not the problem.

I'm pretty sure it is with the construction of the LUT's - since simply changing from one to another on the same 2nd monitor makes a difference ... but why is it a factor at all - what got changed in v10 that makes it dependent on this .... the color grading implementation infrastructure, perhaps ?

I wonder if it might caused by the new ability to zoom to any percentage, instead of fixed levels.

Having the same issue. The v10 update has slowed down my editing on a 2019 MacBook Pro with 32 GB RAM. I'm feeling that Adobe should pay more attention to performance and less to some fancy features.

Zero issues on my 2019 MacBook Pro with 32gigs, but I'm using an external NEC SpectraView where the LUTs are all in the panel and the OS is using a simple matrix profile. It's a display profile issue indeed.

Thank you for posting this.  Same issue here.  Have a top-spec iMac, and browsing thumbnails in Library mode used to be swift-quick.  Now each thumbnail takes considerably longer to load.  Curating photo shoots with 1,000+ photos has just doubled in time for me.  

Another reason why I've disabled all future automatic updates.  I wish I could reinstall previous version actually.  No improvement, just more bugs.  Typical Adobe.

While waiting for a fix from Adobe, read the suggestions submitted by other Mac users who've mostly resolved this problem on their machines. Many other problems are unresolved so it is best to revert to 9.4 on a Mac. 

 

While the other enhancements might not mean much to you they are very useful to fussy users. On Windows the overall improvements are significant we've only been hit with a couple bugs.

I haven't found any resolution to the issue Bill, are you referring to a solution other than rolling back?

I'm not a Mac user but a some people have reported good results with various changes. You'll have to search thru the threads to find their solutions as I didn't track them. Lots of reading ahead for you.

It's sad to see all the slowness people are seeing on their Macs with V10. I have no doubt it's real. 

I am having no issues at all on my 2019 MBP 16". It would be really fascinating to see what the issue is for some users and not others. 

I have also updated to V10 on my standby Win 10 pc and I see no issues there either.

Do you have a color profiled system? If yes, than this would be a miracle.

Yes, all of my computers, MAC and PC are regularly color profiled with i1 Display pro.

FWIW the changing my icc profile from my custom one made via i1Display Pro to iMac standard fixed the laggy scrolling for me.

Unfortunately iMac profile is way too cool.  

For some reason I can't explain after going back and forth between iMac, P3 Display and a couple of my more recent i1Display profiles the laggy scrolling seems to be better even with the profile I was using before.

I need to test more to see for sure...

Just saying, Lightroom would be worthless to me if I can't use my monitor profile as it will be to any professional who needs to deliver work in a colour managed environment. Hopefully what you say may help them fix the bug, have you sent a support ticket with this info?

When I ran my color profiler (ColorMunki) after I installed LR 10, it all works out just fine.
The only two profiles that work for me are sRGB and the newest one I just calibrated. Try running a new profile with your calibrator.

Hi out there, as I read the performnce lack is an issue for us after the jump to LRC10 or PS21. Maybe I need a new Graphic Card. Please help to consider which one. I want the flawless and smooth editing back. If I just edit the CPU is maxed out. The card is limited BAISIC GRAPHIC ACCELERATION.

If you are able to recommend another video card please tell me here.

Thnx Tom

What's your budget? 1st choice would be a Quadro RTX4000 then Quadro P4000 then Quadro P2200. These are all single slot cards that can handle four 4K monitors. GeForce cards are cheaper but not as durable and other than the video chip itself, use lower quality components. The best performing GeForce card per $ for Lightroom is the 2070 Super.

 

For used there is the Quadro K1200. While the P2200 is rated to be over 3 times faster for Lightroom, I didn't see any difference when I upgraded. Don't go below 4GB of RAM as that is the minimum for reasonable performance with a 4K monitor. 

 

One problem with the performance tests is that they are not performed on a wide range of of image sizes. Ideally the whole image will fit in the card memory. If the image has to be processed in chunks then artifacts can occur. Think about sharpening. That works on adjacent pixels. If half of an image can fit in the card then it has to process it in 3 chunks to avoid adjacency effects. Obviously as image size goes up, performance will deteriorate. Moving data back and forth to the card is a bottleneck. So ideally you'll be using a 40 lane processor, 16 lanes for the SSD and 16 for the video card.

 

Also be sure to choose Custom for the video card settings in Preferences, Performance tab. When using the K1200, a Lightroom upgrade killed performance on my system because it switched auto. For my video card and processor combination (very fast processor and moderate speed card), it wasn't fully using the card. Switching to custom and activating full use of the card, I experienced a several fold performance improvement for several of the develop sliders. Adobe is still in learning mode for video cards.

What website do you recommend that would allow us to compare various video cards to the requirements for Lightroom Classic AND Photoshop.

Thanks

@soundrats  My standby/backup machine is a Win 10 PC:

GTX 650

i7-3960

32GB ram

SSDs for system and LrC catalog

LrC v10 has automatically set the "Use graphics processor to Auto - Basic Acceleration.

All LrC functions on that machine work just fine including scrolling through the photo in library and develop. All of the sliders work with instantaneous response in develop as well as cropping and zooming. I was actually surprised that LrC used the old GTX 650 at all.

My main LrC processing machine is also Win 10:

GTX 970 - LrC using full acceleration

i7 8700K

64GB ram

SSDs for OS, programs and LrC catalog and previews.

All LrC functions tested so far work just fine on this machine, too.

I am looking at upgrading my video cards, but after seeing how LrC v10 is using my existing cards, I'm in no hurry.

Also, PS 2021 is using the old GTX 650 for Advanced Drawing mode. The tools I have tested all work fine, too.

All machines regularly calibrated and profiled with Spectraview II and i1 Display Pro.

Bill, Thnx for your answer. Did you really think my video card is causing this issue that my well performing PC turns to a snail after this update to LRC10?

This is what I found out when I first tried version 10.

Turned Use Graphics Processor to Auto in 9.4 and it was still fast. But when I opened 10 now Use Graphics Processor was now set to Auto and it was back to being slow. Does that tell me that 9.4 and 10 share the same preferences. If so why can't they have separate preference files. 10 is not usable with Use Graphics Processor set to Auto so seems something is wrong with Use Graphics Processor in 10.

I am wondering if anyone else with slow down problem in 10 tried turning off Use Graphics Processor. This would at least allow you to use your profiled monitors.

While some folks on this forum, think that Auto is smarter than they are. Not me. I've been hit twice by a Lightroom update switching to auto and causing a dramatic slow down. It is so easy to just:

  • Edit tab
  • Performance tab
  • Choose Custom for Use Graphics Processor
  • check Use GPU for image processing 

And if you have a cpu with a built-in graphics processor in addition to a graphics card, and if the setting is Auto; it sometimes get confused. Why deal with that, Custom just works, Auto only sometimes works.

Changing the GPU settings is one of the first things I did. Made no difference. I've found that when I created a new color profile for my monitor after LR 10 was installed that it works fine, but switching to any other color profile besides sRGB, LR goes into snail mode.

I never tried creating a new monitor profile. I wonder why that would make a difference when that last monitor profile caused a slowdown.

Not sure either, but it worked for me. I even ran several calibrations and all the new ones work, but none of the old ones except for the stock sRGB.

I tried recalibrating and no improvement, but switching to sRGB does resolve the speed issue though not the usability issue as I need calibration to do the work I do.

I'm not questioning whether you need RGB, but.

 

I was a fanatic about always using AdobeRGB until I noticed that for my final presentation, I couldn't see any difference. Whether professionally printed or viewing on my QLED TV, no difference. Until I gave up on it due to continuous driver issues on Windows (works fine on a Mac), I could see subtle differences between a HP 5K RGB monitor and my current Benq and Dell sRGB monitors but the differences were subtle and didn't apply to all images. 

 

Sometimes that we worry about things that in the long run, don't matter. 

 

Aside: several years back, I did a shoot for an art director who insisted on 50MP files. So I up sized some files from 12MP and he couldn't tell the difference. Never found anyone easier to fool than an art director. At the time, the only cameras delivering 50MP files were medium format where a body and set of lenses would have run over $100,000; not in my budget nor was a photographer who used that kind of gear in his.

Caveats first, sources below so you can skip my preaching if you wish.

 

First understand that there is no way to do an overall meaningful benchmark for Lightroom because of the different ways that people use it. For me, Develop is of primary importance and I don't care whether import or export is fast. Others are extensively using presets, plugins and so forth. The monitor resolution and color depth matter as does the size of the files and whether they are RAW or JPEG. Even similar sized files from different camera brands can matter. 

  

Also some features make little or no use of a GPU. GPUs are not unconditionally faster, sometimes much slower. So the benchmark folks mush together a bunch of features which applies to nobody but gives a reasonable overall feel of how Lightroom works. 

 

There is also a difference between what a measurement sees and what a human sees. On an otherwise exactly identical machine, I upgraded from a Quadro K1200 to a Quadro P2200 which is 321% faster. Could I see a difference? No. Could I measure a difference? Yes but not 321%, maybe 10%. 

So for what it's worth:

  • Pugetsystems.com has the best Lightroom specific benchmarks that I've seen. Plus you can download the images and run your own tests though of course, just with your equipment. Because of their tests, I bought the P2200 (my machine came with the K1200) instead of the almost twice as expensive P4000.
      
  • PassMark GPU Compute Benchmark Chart - more an engineering benchmark but still somewhat useful for Lightroom and Photoshop. Just search for the full name to find the latest version. Current link: https://www.videocardbenchmark.net/

This is the list of video cards https://support.apple.com/en-us/HT201805

At least the ones that will give you a boot screen.

I am running a AMD Radeon HD 7950 and it supports the boot screen.

Same issue on my MacBook Pro 2018. LRC 10.0 is very slow. Scrolling is slow and also combining several photographs to a panorama is dramatically slow. Scrolling speed seems to improve, when display profile is changed from default settings to AppleRGB. However, as I would like to stir to my default color profile, I downgraded to 9.4.

Hope this will be fixed pretty soon.

Glad to know I'm not the only one - took me some time to find the right thread.

cMP 5.1 running on Mojave 10.14.6

2 x 3.46GHz 6-core Xeon

64GB 1333MHz DDR3 RAM

Radeon RX 580 8GB

Lightroom catalogs are on NVMe in slot 2, however,

scrolling through library module has been an excruciating experience.

Should have reverted to 9.4 right away but having worked already on buggy v10 catalog, no turning back on current year's catalog...

At least Adobe is aware of the situation...

Performance tip, I started with a similar setup on a Windows Xeon workstation except I have only one 3.6/4.0 Xeon with a Quadro 5GB P2200 video card.  

 

Began with Lightroom components split across 3 SSDs. With the images in the GoogleDrive folder. Was seeing a 1-2 second delay with every drag of a develop slider. 

Moved the images to a separate folder and periodically sync them to the Google Drive folder. Huge improvement because every image edit results in a write to the XMP file and the catalog whereby Google software locks the files until they are successfully uploaded. 

Then I put a Samsung 2TB SSD on a PCIe adapter and moved all Lightroom components to that drive. Nice but modest improvement. Then using Samsung Magician, set that drive to RAPID mode choosing it to accelerate both overall system performance and to manage TRIM. Very noticeable performance improvement though unfortunately I didn't do any measurements. 

 

Through all this, the Lightroom software components were left on the NVMe system drive.

What does this have to do with the original post? Would be best to start a new thread or find a Windows or overall performance tip thread.

Hello I am working with the MACpRo 2013 and Mojave. Since I upgraded to Lightroom Classic, Lightroom has been running extremely slowly. Is this also due to my Spyder profile?

Possibly the display profile as some have reported. If you load a simple sRGB profile instead, any better?

Same problem. 10.0 is completely unusable. I get a spinning beach-ball with every click for 5-10 seconds, incredibly laggy.

2013 Mac Pro, 6-core, 32GB RAM, FirePro D700, SSD, Mojave 10.14.6

I had to downgrade back to 9.4.
