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

Hey Victoria, 

thx for the quick reply. It's 10.1.

The "downgrade" to 9.4. worked  and seems to solve the problem. (despite that the Catalogue can`t be used anymore.....)

I will try and "downgrade" PS as well....

Same issue here. Extremely slow on a MacPro 5.1. It only gets back to normal when using "Apple rgb" or "sRGB" profile. With any other profile it's damn slow.

For all of you having slowdowns related to your custom monitor profiles, it might be worth re-calibrating and re-profiling with different software to see if a profile generated by a different algorithm will allow you to stay in a color-managed workflow.

DisplayCal & ArgylCMS are free, open source color management & profiling tools that are worth trying.  Photography Life just recently did a thorough write-up on how to use them:

https://photographylife.com/how-to-calibrate-apple-mac-monitor

The article is focused on using them on a Mac but they also work on Windows PCs.

Thanks for the suggestion, are you experiencing any slow down with profiles from these software?

I'd be hard pressed to believe it's the profile software for the display only because, I sent a profile from my end, where I have absolutely no issues (SpectraView/MacBook Pro) to someone who was having issues and that profile didn't fix his problem. There's something about the sRGB profile or how it's used that seems to fix this issue. I mean it can't hurt to try a different product but I'd be shocked if one product worked and another didn't, all settings (like V2 spec) being the same.

No, I've never experienced the profile-related slowdowns.  I've always used DisplayCAL and my installation of Lightroom Classic 10.0 and later 10.1 run as fast as they do with the sRGB monitor profile.

I actually had hoped switching to sRGB would magically make my Classic speedy again.  Sadly, my own performance issues are of the more mundane variety- those baked into the software architecture of Lightroom Classic.

Right and I've never experienced the profile-related slowdowns with Spectraview but some have. It's a combination of additional factors.

I have experienced the slowdown and also on the same computer with the same monitor after having another monitor on not having a slowdown. And, then putting the old monitor back with the same profile as before and not having the slowdown, recalibrating and new profile with the same software and again not having a slowdown. I am totally baffled by what happened but I am pretty sure it is not the profile.

If you system is behaving as described in the Official Post on this thread, no need to start a new thread or provide any information. 

If you system behaves differently, then you should start a new thread with complete information.

Review the official post on Page 1 to determine how to proceed.

*Mayuri Jain  @Rikk  Switching to the sRGB profile fixed the insanely slow scrolling in the library view, but of course the colors are wrong. Thanks for the temporary fix!

Hi Rikk,

macOS Catalina 10.15.7

Retina 5K, 27-inch, Late 2014

3.5 GHz Quad-Core Intel Core i5

32 GB 1600 MHz DDR3

AMD Radeon R9 M29OX 2 GB

Just adding my similar experience to this thread.  In Develop module, I can move right along for about 10-15 minutes and then the cursor starts to freeze up and changes are first very slow, then impossible.  And then the grey blocks appear.  Tried various solutions suggested in this thread to no avail.  Will revert to earlier version of LRC.

Solved: reduce screen resolution to I.e. 2560x... and it all is back to super fast. For quick editing in grid view, that’s okay.

I have recently switched to a 5K retina display so that may have contributed to a slowdown. But again, having much worse browsing performances in the Library module than in the Develop module does not look right...

Adobe Lightroom Classic GPU FAQ

How does Lightroom Classic use the graphics processor?

When configured (Preferences > Performance), Lightroom Classic can use a compatible graphics processor (also called a graphics card, video card, or GPU) to speed up tasks of displaying and adjusting images in the Develop module, the Library module's Grid view, Loupe view, and Filmstrip. Enhance Details is also accelerated by the GPU. Using a compatible GPU can provide significant speed improvements on high-resolution displays, such as 4K and 5K monitors.

No difference in speed noted when running 4K... strange, although LRC marks the GPU as “acknowledged”

I am running a fully specced 2013 MacPro (12-core CPU, 64GB RAM, 2 x AMD FirePro D700 GPUs) and LR 10 froze my machine so completely that I could not even force-quit. The only thing I could do is a hard reset. I've never had any program render my Mac unusable before. That's really not acceptable.

 I solved that problem by turning off GPU acceleration.

@Rikk With respect, this is two months old, and the issue is still not resolved. LR 10 is simply not ready for professional work. Adobe should not have released it.

FWIW, if I switch to sRGB calibration (from Eizo Color Navigator) and vanilla sRGB Profile, Lr 10.1 goes like s**t off a shovel.  Otherwise it just goes like s**t.

But I didn't invest in a Mac Pro, twin Eizo monitors and, indeed, an Adobe subscription to do photo editing in sRGB.

I own licenses to several comparable applications to Lr, developed by teams with far, far less resources, and non of them of them have any issue with using a "professional" ICC profile. 

So I'll add my voice to the chorus of "when exactly, are your chums going to fix this, Rikk?".  If they're not, I'm sure I can safely assume you're arranging a refund ? After all, if it is such a small number of subscribers (not "users", "subscribers") then cancelling subscription fees until this disaster gets fixed is hardly going to impact Adobe's beloved bottom line, is it?
