P: Slow UI when using Mac and Custom Display Profile

[adamcrowe]

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 have 9.4 installed and I don't get an update notification, is that because I have to update to the ( not working ) 10.2 version to then get notified ?

[Nikolaus Netzer]

@Rikk Update is awesome. Scrolls and zooms absolutely fluid.

@Rikk 

Hi Rikk, I'm on LRC 10.1.1 but am not being offered option to update.

Any idea why?

Thanks

[nitin.chandra]

There seems to be no proper workflow from LR to PS for the super-resolution...Am I missing something?

[zobeleye]

please stick to the topic or open a new thread

@Rikk 

Thanks for the good news !

No update yet in Belgium-fr CC

I suppose availability depends on specific criteria like geographical area and/or language localization.

If it does, is there a schedule you could communicate ?

Thanks.

[Rikk Flohr: Photography]

It takes up to 24 hours for worldwide server propagation.  Make sure you refresh your Creative Cloud app to see the update. 

[FloCal]

Ok, thanks, I did it and it appeared. But why is it necessary to refresh the CC app ? Usually the new updates show up as soon as they are available. I never had to refresh to see the updates…

[Victoria Bampton LR Queen]

@FCbee they get pushed out slowly around the world to avoid crashing the servers, refreshing just does a manual check for updates so you get them before they get pushed out

[Lhotka]

Vastly better, thanks for getting it out at long last :-).

@bill_3305731 FWIW, re: GPU, LR doesn't seem to use it very much at all.  There's no visible difference in how responsive the application is, and even making adjustments doesn't show substantial improvement between the eGPU and the internal.  I'm going to sell the eGPU now while the market is hot, and then wait for an Mx machine this fall.

@Rikk I'm happy to say that this update has made Lightroom more than just usable again. It's more responsive than it's been for years. A big thank you to Adobe for really getting this right.

[jlehet]

Sometimes, like yesterday, it would take some time between opening LR and the slowdown, so I'm not yet going to say I'm 100% sure this is fixed, but I'm about 95% sure. Launched it about an hour ago. This is way faster and keeps up with me instead of lagging my actions as it was yesterday. Thanks!

[astrosven]

Thank you LR Team - solved with LR 10.2!

[stex07]

Many thanks to Adobe for fixing this. My experience today suggests that the previous unworkably slow performance of 10.1.1 has been completely solved by this update. 

[jlehet]

Yeah, I'm now 100% sure. 10.2 is faster than I've seen LR in a good while!

@Victoria_Bampton_Lightroom_Queen 

Got it, thanks !

@nitinchandra Lightroom cannot yet create super resolution files. Announced to be available with a future update. 

[Lhotka]

*timerickson Definitely seeing the scroll lag on the sidebar (right at the 'annoying' threshold), and also the choppy loading when thumbnails are larger.  Would say it's back to LR 8 / MBP 2017 level performance...which is certainly an improvement over recent versions, and definitely livable.  

What's interesting is that once I scroll through a whole folder, then the choppiness seems to improve substantially, so it's like it's rebuilding the previews for the larger thumbnails (I'm set to standard, not 1-1).

Using a 2019 MBP/32 GB/8-Core/Radeon 550M/thunderbolt SSD/4K monitor system.

Re: GPU effectiveness. The net benefit depends on the power of the CPU and the size of the RAW files. Run an i5 and 16GB of RAM and the improvement in Develop module sliders can be 10x. On my 6-core 12-thread Xeon, most of sliders show a small but appreciated speed-up. Resolution and noise sliders about 4X, almost instantaneous, really appreciated. One of the sliders doesn't use the GPU but I've forgotten which one. It does use all the threads so performance is fine. These comments are based on a Quadro P2200 with 5GB of RAM. There are other functions that use the GPU but all I care about are the Develop sliders. Lightroom Queen has a new article about Lightroom's use of a GPU, need to check it out. 

Also anxious about the impact of various video cards on Super Resolution. Hopefully we won't need one of those 64GB modeling cards that are the price of a really nice used BMW. 

[Lhotka]

Yeah, for me I was more looking for UI performance gains - the 5700XT didn't touch that at all.  The develop sliders were faster (50MB NEF files mostly, but some GB sized panos too), but not enough to warrant the investment in hardware.  Pano and HDR didn't seem to change at all.  

Hopefully the Mx GPU is leveraged better.

[MCHM]

Has the problem with the "RAM memory not being released" been taken care of?

[Barrie Spence]

@Rikk (edited) are you *sure* it's completly fixed? 

Quick collection ... massively improved.

Folders... massively improved.

Collections ... massively improved.

Publish services ... hmm or nope. 

Certainly a publish service to disk is still treacle in the library and it is deftly affected by the screen profile (that was what I had open after the update and why initially thought it wasn't fixed).

Other third-party publish services (Smugmug, J Friedl's Flickr plugin, LR/Instagram) are maybe a little better than the built-in disk service, but they are not as snappy as collections or folders.

Switching to a sRGB profile fixes performance in all the publish services.  So isn't completely fixed.

MacPro 2010 32GB RAM, Mojave 10.14.6, RX560 4GB.

Eizo CS2730, ICC profile from Eizo ColorNavigator (profile version 4.2).

And no, using an sRGB screen profile isn't a good workaround (I'm cringing at how bad my recent output might look with a proper screen profile).

[Lumigraphics]

Is that machine even supported? I'm not certain of the cutoff for Mojave and that video card.

[Barrie Spence]

@lumigraphics yip it's fine. I think what I'm seeing is a slightly different problem. I'll elaborate on that separately.

Hi Barrie,

my experience using a Mac Pro 2012 5.1 64 Go 2x3.33GHz, Sapphire Radeon RX580 8Go, Asus ProArt 32" 3840x2160 :

As long as I was using Mojave 10.14.6 with Lightroom 10.0 or 10.1, switching to sRGB was really better. After updating (not a clean install) my system with Big Sur (thanks to OpenCore since the Mac Pro 2012 is not supported by Apple anymore), LR 10.1  Library view was very slow ***whatever the profile*** (including sRGB...). But now, switching to LR 10.2 solved everything while I still use the Adobe RGB 98 profiles v2 created with Mojave. 

I'm not sure that can help you but it proves that this is not easy....
