Lightroom Classic CC 7.4 Is Completely Unusable

  • Updated 2 months ago
I am using a small test catalog of just 115 photos with Lightroom Classic CC 7.4, using some raws, JPGS, TIFFs and PSDs. Performance is STILL so laggy it's unusable. Going from Library to Develop takes anywhere from 10 to 20 seconds to load a photo as does going from one raw or psd file while in the Develop module. At first I thought it was an issue having tons of presets showing, so I folded them up, and the same issue that was in 7.3.2 is still present... Reboots, closing all apps except Lr, have no positive effect. 

I've now reverted back to Lightroom Classic CC 7.2 Everything is back to normal and very responsive. I've wasted untold hours fighting with the latest official 7.4 upgrade and trying everything possible to get it to work has been all for naught. More than 24 hours just updating all the presets I have is just ridiculous.   

It's truly sad that at this point I cannot go forward with my main catalogs which have upwards of 45,000 images in them. As new updates come out, hopefully with a fix, I may be able to continue with Lightroom but for the meantime I will stick with the older version but as I have no faith that there will be a fix anytime soon, I am now migrating all of my images to the stand-alone version of Capture One Pro which is by far infinitely faster and better in so many ways. If this is the way of the future with Lightroom Classic CC, I am not going to continue paying a subscription for software that cannot be updated. The fact that those who can't migrate to the newer updates miss out on things such as camera and lens profiles is also really just ridiculous. As a Lightroom instructor for the largest photography meetup group in Canada, I cannot teach a course on the new features of Lightroom nor will I now recommend this software to my students.

PS- Not Apple’s or Adobe’s fault, adding features which people want increases the RAM needed to run it. Adobe should do updates for awhile that just optimize the app WITHOUT adding new features, so our devices can catch up.

So... Up till 7.2 works great.. as did 7.3.1... no issues at all.. but all of a sudden 7.4 breaks my ability to Lightroom due to a memory issue? I'm actually using 7.2 with my huge 45,000 image catalog with over 16,000 presets with no lag, no problems at all with only 8GB ram, on my MacBook Air.  HDR, round-tripping to Photoshop, are a breeze. I have no issues with memory at all. I reboot maybe once every couple weeks. I also have a 2011 iMac which I cleaned up completely and it has 16GB of RAM and runs 7.2 perfectly fine and is my main production machine. You might want to try a full reinstall of your OS from scratch and keep your computer clean.. that doesn't sound like you have an ideal system, and those thing you have mentioned are what forced me to clean my iMac and start fresh and it's been clear sailing ever since.

Also, I was beta testing 7.4.1 ... 2... 3... 4... 5... and 6... out of all those, only 7.4.4 and 7.4.5 had no lag issues...7.4.6 and the final release all have lag... This is an Adobe problem, not a RAM problem.  

As mentioned in my comment I'll stick with 7.2 for now and miss out on my Canon EF 85mm f/1.4L IS USM lens profile and also miss out on updating Photoshop because of a Camera RAW mismatch going forward. I've already bought and started using Capture One Pro stand-alone and will use Photoshop for just editing from that program. Adobe has lost my trust and my business at this point.

I'm not saying  that it's anyone's "fault" per se, I'm just saying it worked and now it doesn't work.. even in the beta point releases as mentioned above they fixed it and then it was not working. Now it's "broken." If Adobe addressed in the final update that would have been great. As it is, they haven't fixed it. I submitted a report to them with the same information hoping they would do so before releasing 7.4 final release, but that was asking too much. I wasn't the only one to report this. One thing is for certain, and it has nothing whatsoever to do with RAM. I've also worked in IT for over 20 years in a major bank, and if you're having to reboot daily, back up everything on your Mac and completely reinstall macOS with a bootable USB key, partitioning and reformatting the drive before doing so. Then only install the stuff you need... I used Memory Clean in the past and it ended up casing more problems then it fixed. I have Activity Monitor up at all times and sometimes have to close an app (Path Finder) which eats up resources.

Unfortunately, I share your experience with 7.4. Import is erratic and export very slow. and most of my presets disappeard when updating. I work on Win 10, 32 GB of fast RAM plus adobe on a very fast SSD of 1 TB capacity. seriously: I would quit my subscription immediately if there happened to be an alternative. It is deeply frustrating to see that Adobe is making huge profits but can't get their act together

Whew.  Guess I'm lucky.  My upgrade from 7.2 (I had to roll back from 7.3.1) went very smoothly.  My catalog is tracking 280,000 images and my 9 year old Dell has 12gb of ram.  All my preset are present and converted in seconds.  My imports and culling process, have never been faster.

Lightroom is now unreliable for a professional photographer.I just updated to 7.4 and it is so slow, adds extra time and frustration to an already long day of shooting pictures. I take on average 500 to 1300 photos a day (more time wasted posting this) I don't have energy or patience for import & export crashes. I have an extremely fast modern computer with SSHD packed full of RAM with the fastest intel chipset you can buy. This is ridiculous.Catalog opimized of course. Plenty of extra local SSHD memory allocated, no other processes in backround. All the sync auto xmp etc. turned off. Windows full updated... It's just like the program is not compadible with Windows or something crazy. You guys at Adobe need to resolve this, and very quick. I have already called Adobe and reported several major bugs... but running slow is not negotiable. I want my money back.

Well after uninstalling Lr Classic altogether, and reinstalling Lr Classic CC 7.4, I have tried something. I took the small catalog originally mentioned above, and created an entirely new catalog for those photos. Imported/Added them to the catalog.. everything was awesome.. speedy.. no problems.. Then I added back in the custom presets I had in the previous catalog.. just a copy and pasted (after shutting Lr down).. when reopened.. sure enough.. there was the lag.. 10-15 seconds just to go between images. Bear in mind that I took pains to close every other app on the Mac.... and had created 1:1 previews first. There were around 6,000 presets added... and in Develop I had them folded up. 

I've given up and have gone back to 7.2 where these issues don't exist. To be sure, I noted most of what's above in the original post during the beta phase but no one at Adobe even responded to it, let alone fix it.

If I can't use an editing software that originally could (and can) sustain 16,000+ presets (not just the 6,000 I used in this catalog in it's latest iteration then there is something very wrong. What is the limit I need to keep my presets to now? It's not worth the hassle for some gimmicky additions that Adobe thinks are going to make some kind of difference going forward. It's a shame that I'll be paying full price for only being able to upgrade Photoshop, until that gets broken as well. Capture One will ultimately be my Lr replacement at this point, but I still need Photoshop, at least for now.

While I echo Christian's comment.... What about the setting in Preferences / Develop / Enable hover preview. Try it disabled - restarting LR after changing the setting.

Thanks John, I've done all that as well as completely rebooting, and Christian, how many presets a person "needs" is not the point... the point is they all worked flawlessly before but now don't. Even during my beta testing with Adobe, some iterations of point releases worked fine, but the final release went back to being incredibly slow and unusable. And by the way, I boiled it down to around 500 presets and there is still lag. I wonder about all the people who have bought tons of presets and may run into this issue. Maybe they'll fix it, or maybe at this point they don't really care to. I'm moving back to 7.2 for production and moving on to Capture One Pro which has no lag whatsoever.  Not on importing photos, making previews, editing, etc. It just works.

Since you do beta testing for Adobe, you should notify them about the difference between the last beta and the final release. Maybe there is something off in their build cycle....

will, money back wouldn't help, since we know that there is no real alternative to LR, and I am sure Adobe Techies won't do that just to annoy us. I also know it can be very difficult to diagnose whats going wrong, particularly, whe faults are erratic. with versions 7.3 and .4 I had so many different problems that I really couldn't pinpoint where the fault lies.

I have found if I simply add keyword presets after importing, seems to not slow me down. I still can't really do anything other then watch a progress bar while importing. Keywords or not. Everything else in Lightroom is pretty fast once the files are imported and then converted to DNG.. . Something wrong with the new import function...

That is one way of going about it. I am going to test with your keyword list and see if I can duplicate what you are seeing. If so, I will file it with the team. Thanks for your patience.

Thanks, Victoria, and all... it seems to have done the trick. I uninstalled LR from the Creative Cloud menue, but not before I made sure that LR would keep my previously installed plugins or presets. After I had re-installed the program, Lightroom Classic starts much quicker now, import is really fast and editing a real joy. May be, Adobe should add a little piece of advice to all customers experiencing similar problems. thxs once again

Sorry, what was the fix? My exports are painfully slow.
