Lightroom Classic: Slow UI when using Mac and Custom Display Profile

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

with 9.4 the sys runs smoothly with my 32GB. If that is really the case, that the new version needs more than that, then we all have to buy a new M1 mac. I personally find it shocking to consider that they would do such a thing...

That is not it. 96GB and I see the same slowness with 10LR. The Library module in LR10 is not using the GPU.

32GB is plenty to run Lightroom well with only modest improvements with more memory. Don't forget what else you might be running concurrently that is using RAM, the machine needs to be sized for all concurrent resource consumption. 

 

With 16GB on a Windows machine, it runs quite well if only a few browser windows are open (Edge or Chrome but not IE or Firefox) and using Windows Defender instead of a 3rd party antimalware tool.

Lightroom Classic 10.1 brought my iMac late 2015 to a halt and forced reboot, and the crash disabled the Bluetooth keyboard and Magic Mouse II when I rebooted.  I've dropped back to LRC 10.0, which appears to work better.  Also, changed the monitor profile to Adobe RGB (1998) rather than a display profile generated by a colorimeter.  A Windows laptop with 16GB ram and a 4 GB graphics card seems to work better.   Photoshop on the Windows laptop (Dell Inspiron 2018) works fine and also seems to be okay on the iMac.   I've noticed that many of the people reporting problems were on iMacs from late 2015).

I've been having similar issues as some identified. Develop module painfully slow, freezes my MacBook, unusable essentially unless you are doing only minor edits. 

I reverted back to V 9.4 and so far this seems to have "fixed" the problem, although it has created another, ie I can not use my most recent catalogue, LR won't let me open it, says the version is too new so I had to go back to an older catalogue and start the process of reloading my newer images. Bit is a pain, I'd say but at least now I can do my work.

I just noticed that my system shows a great boost in Library performance on my 4K BenQ SW271 with Adobe RGB color profile (calibrated using i1) when changing the display resolution to "unscaled full 3840x2160" in BigSur. Way better than any scaled resolution which I usually applied before.

It's probably the same as running LR in Low-Res (Non-Retina) mode.

Hello everybody! I must also share the problems I face with new Lightroom and some potential "releaf actions" untill a proper update will come out to solve the problem.

My system is:
Apple Mac Pro 5.1 (2012)
x2 CPU Intel XEON x5690 3,45GHz
96GB RAM
NVME SSD for Cataloge and Photos
AMD RX VEGA 56 8GB

My system works great with all other software except the new version of Lr Classic. It is so laggy I cannot work with it at all.

Before I share my potential releaf solutions I should mention that my computer used to work the new Lr Classic great with my previous monitor which was a 28'' 4K (DisplayPort connected).
Once I bought 4 new monitors 32'' 4K in order to review them and keep the best, I realised that all of them found so dificult to work with Lr Classic. So it has to be something about the UI of the software and how it scales itself to work on larger displays.

One releaf solution was to make Lightroom work in "Low Resolution". It seems to increase the performance. I made a video about that:

That way I can work with the new version (because all my cataloges are converted to the new standards and I cannot go back) a little bit faster. Nothing like compared to the snappy experience with my 28'' 4K monitor, but it looks better.

Another work around is if you work with a 4K 30+ inches display, to make Lr work on a smaller window and not full screen. Working Lr as Full HD on a 4K display seems to make the software run better. You can also try to lower the resolution of the 4K display to Full HD dimensions, but what's the point to have a 4K monitor then.

The only way I was able to work the new Lr Classic on Full Screen on my 32'' 4K monitor was with Lr running on low res (video above) and changing the Calibration to sRGB. Of course I am not feeling well working my expensive monitor on a non calibrated profile, but I hope it is just a "buying some time" solution to this problem.

I hope Adobe will come up with something stable next days!

My system is near identical to yours, so your tip is welcome. Fortunately, I do not rely on Lightroom for my living and even more, fortunately, I was able to roll back to the previous version, so the issue is not as serious for me as for many others.

I just did the latest update for LR and I can barely get the tabs to slide. I’ve never seen it so slow. I get white squares across the picture like it’s still loading. When I logged on my iPad none of the changes were there and it crashed. How do I back this out?  It’s totally useless to me.

Since I upgraded LRC to 10.1, LRC is running extremely slowly and occasionally crashing on my iMAC (2018) running Mojave 10.14.6. Frequent delays when scrolling and editing.  Even switching from Library to Develop.  And it hangs when I go between FIT and 100% on Navigator. Either LRC hangs, quits or the iMAC crashes.

Been configuring the new MacPro which has the W5700X GPU. First off before it arrived I did a clean install of 10.15.7 on the MBP and migrated the production OS 10.14.6 to it. It was my intention to do a clean install of everything which I have a partition started but thought I would go ahead and use the migrated partition if everything was working ok. 

Now to the LR10.1 Library Module test on the migrated partition. An AOC monitor with the display profile was hooked up first and the test showed no slowness. Then hooked it up to my two NEC monitors that I normally use and selected the two display profiles from the old MP5.1 that appeared to cause the slowdowns. Still no change LR10.1 was as fast as before. just as fast 9.4. So I went and did a new calibration of both monitors and still no slow down.

Not sure what to make of this. Was it a clean install of the OS or the GPU making that much of a difference? Surly others have tried this. By the way the GPU history still shows no activity when in the Library Module, in fact what I found strange was compared with the GPU in the MP5.1 there was absolutely no activity in the GPU History. Make me wonder if there is not some not so kosher attempt at using the GPU for some reason going on when the slowness is showing.

seriously ADOBE, what are you guys doing with LR ???

why is this not being fixed ? first 10 and then 10.1 ??? and still the same ???

At least some info on your progress would be appreciated...

same here, went back to 9.4 and did the move to 10.1 today, just to realise, no change. STILL SUPER SLOW... it unusable (and even 9.4 is too slow - by the way)

Just curious @eschhols, what is slow in 9.4? Just generally slow or any comparison to some?

Easy to explain: goto grid and move from one picture to the other an wait for the spinning beach ball… for ages.. its damn slow just to display the pictures. Okay, I’ve got a couple, bit is 10.000+ really an issue for a professional app? - this relates to 10.1 - 9.4 is okay-ish but could be faster..

Best

I have around 30k+ images in one catalog and have all the previews built (I leave it overnight to build previews on a fresh install). Works fine on my iMac and MacBook Pro. Maybe having the catalog and previews on a SSD helps...

This is not applicable to LR 10 though...9.4 works fine.

SSD: This is kind of old but I believe still pertinent and very well researched and written:

You can scroll to the conclusions if you want it 'quick and clean'.

Same. Mac Pro 5,1, Mojave, 2x 6-core 3.46GHz, 96GB RAM, Radeon 580RX, Samsung EVO SSD driven on an ACHI controller.
Three screens, the main 4K display running at 3840x2160 and two 1920x1080.
No matter the setting LR 10 is CRAWLING.

One would think it's a decent computer and Lightroom 10 brings it to its knees – no, it makes the machine unusable... Every move in LR takes eons to complete.

Activity monitor shows hardly any processor use & any setting regarding GPU performance or resolution makes no difference. Photoshop performance is a-OK, but it's not my main tool anymore. I'm seriously considering a.) switching to Windows b.) Ditching Adobe altogether (unfortunately we don't have many options in our industry.)

The same software runs OK on another 5,1 with High Sierra and lesser RAM, processing and graphics power and on a little MacBook Air & Mojave with an HD monitor. Go figure. 

Edit: the other machine maxed out on 9.4 w/ High Sierra and I'll try to downgrade on my main machine. Not happy.

Hi Markus, hope you’re well. I did a workshop with you in NYC a good few years ago when I was visiting from Scotland. Itching to come back.

Some reading this forum will identify temporary solutions as your machine has plenty of power. I'd start with comparing your slow and fast systems to find the differences:

  • plugins 
  • monitor calibration 
  • monitor color space
  • ... 

Yes we windows users have experienced very few problems with V10 and even fewer with V10.1 but I assume that you have a good business reason for choosing Apple products.

Yeah... None of these hot fixes bring sufficient relief. I downgraded to 9.4 and I'm working with an older catalog for now – until –or if– this can be resolved. Sometimes updating just does not make sense & the older version performs exactly as it should.

From my experience I would guess it is probably the GPU and/or its drivers.

I would make a test clean install partition on the machine that has the problems and see if it makes any difference. If not then it is probably the GPU and/or its drivers

Can you link to that Office Response - I've not been able to figure out where that is - there's so many threads about this issue.

I switched my monitor profile to sRGB with v10 and I had the recollection that it more or less fixed the issue. Now, in v10.1, the Library module is again much slower to browse than the Develop module. And that's with sRGB. With a custom profile, the Library module is just unusable.

I use a MP6,1 12 cores with 64 GB RAM - catalog and photos on M.2 SSDs - using either the D500 or a VEGA 56 in an eGPU, connected to a 5K screen.

This comment might be out of date but Lightroom with an eGPU used to either not work at all or delivered terrible performance. At least a year ago, I was researching an eGPU to use with a HP 5K monitor.

I did not identify an obvious link between Lightroom performance issues and the use of eGPU. In this particular case (Library module much slower than the Develop one), the use of the internal GPU or eGPU does not seem to make any difference.

Same here. Lightroom Classic 10.1 is absolutely slow and laggy. Switching the display profile to Internet sRGB and speed is back to normal. Selecting any other profile and Lightroom is slow again.

@mac_nick Did you do a clean install of the OS and then LR10.1?

No. OS was stock. LR update was the background install through Creative Cloud.

I have not installed LR10.1 on the stock OS that came with the machine. The new install on new partition plus migration form the old machine/Mojave is working fine though at some point when time permits I do want to do clean install of the apps I use on the clean OS partition. I will do an install of LR10.1 first to test.
