Lightroom Classic 7.3: Slow switching from Library to develop, zooming in, using brushes

After the update to 7.3, Lightroom has become unusably slow. Regardless what you do (Switching from Library to develop, zooming in, using brushes). 

It is laggy to the extent where a normal workflow is not possible any more. 

Using an 8-core AMD 3.1Ghz, with 16GB of RAM and an Nvidia GTX960 under Win10 64bit. 

Pls. advise.

Have you tried completely uninstalling and reinstalling? I'm hearing a few reports of that solving performance issues in this release.

Yeah - first thing I did. Unfortunately without success. While the previous version provided notable speed improvements - it's now worse than it was before Adobe worked on the performance :-(

Was slow immediately after upgrading? Did you let it sit open overnight for all the updates to ripple through the catalog? If so, is performance better today?

Unfortunately yes. I had the machine running yesterday for 10-12 hours with LR open in the background. But honestly I did not notice, Lightroom was doing something during that time at all. How can I check if there are still background tasks ongoing?

I have the same problem:  I've upgraded Lr classic 7, and was looking forward to enjoying the new features. To my great disappointment Lr started working so slowly that I can hardly process my photos in it. It annoys a lot just to list presets, to say nothing to work in develop mode.
 How can I fix this problem? Can I upgrade it one more time? I'm afraid to reinstall Lr because I don't want to lose my albums, which I  had once in my practice..

I'm also experiencing slow performance with this release. I've restarted my computer but the problems still exist.

Specific slowdowns:

Switching between photos in the Develop module, even when Smart Previews have been generated. I've even changed the standard preview size to a size smaller than my 4K monitor. Happens on my Fuji XT-2, XPro2 RAW files (compressed) and Fuji jpegs. Haven't yet tested my Canon files.

Slow previews when scrolling over presets. It used to simply preview in the navigator window, but now it previews simultaneously the on-screen images at preview-size which makes everything reaaaaalllllllyyyyy slow. I don't like this feature but can't find a way to turn it off.

Pasting copied settings. Too much delay now. 

I've since rolled back to 7.2 until these performance issues are resolved.

i7 4770K, 32GB RAM, Win 10 64, GTX 1070 8GB card, 4K monitor.

How do you roll back to 7.2? I am finding that adjustments are really slow to be made, and though there are some great improvements in version 7.3, they are just not worth the slower speed. Or is upgrading from 12GB to 16GB on a Mac likely to make all the difference (the memory is ordered and on its way).

In the Adobe CC app, you can find a menu listed beside the LR app when you click to expand it. There, it gives the option to roll back to previous versions.

Sorry, but if I click on the arrow to the right of "OPen" the only options are "View tutorials" and "Uninstall". The arrow to the left gives nothing.

Thanks. It worked eventually. However, to get the option to roll back, I had to uninstall all versions of Lightroom CC. I reinstalled Adobe CC Desktop App and then found I had to log in with a different Adobe ID. Not sure how I ended up with two.

My experience incl videos. Unusable slow GUI overall. Compared with 7.2 in video.

My experience: version 7.3 is now slow in zooming, generating 100% previews in develop. 16 mpixel image = two seconds..Mac pro classic 3.33, 12 core, Amd 3 Gb. 48 GB ram. Version 7.2 was instant zooming in develop

I've just done an interesting test!

I got Lightroom 7.3 to make a pano from 10 vertical D800E images - this it did without too much of a sweat, and the result is a DNG at 33,300 pixels and 970Mb.

If I try to add even a graduated filter to this not-so-massive DNG then the Dev module crawls to a halt - just placing the filter takes nearly 2 minutes of spinning progress indicator.

However!

If I close Lightroom and open the DNG in ACR, then I can apply any adjustment I like and there is no slowing down of anything.

So why would ACR act normally and the Lr7.3 dev module act like it's been shot with a very big gun??

Not only raw processing is very slow, but also basic GUI functions like dragging a panel around, switching from one view to another, minimizing, etc.

Today it was so particularly slow for me that I had to record a video



Its so unusable at this point that I'm wondering if I should ask for a refund until they find a solution.

Sorry for the poor quality, I had to record with my phone as screen recorders wouldn't work with lightroom sucking up all computer resources.

Same here, crazy slow on high end rig (8700k + 1080ti + 1TB NVME + 16GB RAM), specially all local adjustments, switching modules and general GUI lag.

Hi Al Fresco, I am having similar (same?) issues. Has your system improved with LRCC 7.4 release? Did you find any other solutions/improvements?

Cheers, Harvey

Same here.  Super slow rendering of ALL local adjustments, changing from Develop to Library Modules, and zooming in/out.

I wonder how long it will take them to make a patch...? This release was a total disaster, but I'm used to it by now.

7.3.1 just came out a couple of hours ago. I'm not certain if it fixed this issue as I wasn't able to reproduce it, but you could give it a try to find out.

Hi Philipp, same issues for me. Working on my photos has stopped - it's all problem-solving at the moment and has been for several months now.

I also did the re-install and made new smaller catalogs and all sorts of other little adjustments including the 7.4 update with no real improvement. My system is a new, fast iMac with 32gb ram and a SSD, which apparently well exceeds the minimum spec.

In my experience LR gets a bit erratic; sometimes takes 90 secs to change from Develop to Library module, if the program has been in the background. Showing/hiding masks may not work at all when clicking on edit pins and can take up to 90-100 seconds when selecting the checkbox. The brush lags so much that painting layers of adjustment is not functional.

It's become so frustrating I'm exploring migrating to other platforms to ease the pain! 

All very frustrating for a program that I use constantly and love enormously (when it works well!)

Same for me

I noticed that on my side disabling GPU support made things less laborious.
(Moreover, advanced tests have allowed me to see that the GPU was never solicited apart from the use of brushes, while slowing down everything else - usage advantage almost to zero all along)

Without the GPU it is more livable but, even downgrading the version of lightroom to the last but one can not reprofit with a proper speed thanks to the CPU + GPU

Please correct this defect, I spend hours on my photos ...

* Another problem appeared with the last 2 versions:
Full screen display bug on OSX latest version + iMac 5K.
as soon as we switch to another "desktop" or that we click elsewhere than in LR are display takes odd proportion until it becomes normal after a click in the app.


Courage and thank you to the develloppers for their work to make LR always more functional and powerful (a preference for me for the overall fluidity of the application, do not hesitate to load my GPU there is margin! ;))
