Starting off with the most up to date system info post:
The summary of the problem is basically laggy / insufferably slow performance issues with LR CC running on a system as follows:
- i7 4790k @ 4Ghz
- 32Gb RAM
- SSD Catalog
- 2x HGST 5Tb RAID 1 image host drives
- nVidia 970 GTX
- 2560 x 1440 display, LR in Single Display mode only
- Windows 10 Pro 64bit
I have been engaged with Adobe on this issue for several months, during which time I have kept my display drivers and lightroom up to date.
Performance *HAS* improved slightly since 6.10 but is still not at a point where it is comfortable to smoothly work. Every operation has a lag / UI update that just makes the whole experience jarring. The memory leak that would send LR to its knees was indeed resolved with 6.10, so performance no longer degrades as rapidly over time as it used to, however baseline performance is still not what I'd expect and is certainly not comfortable to work with. Editing in Lightroom is a headache to be dreaded right now, so much so that I've been putting off jobs that I really shouldn't be.
This initial video opened up the dialog with Adobe, and was recorded on 6.8. This is the best performance I ever see from LR as it was freshly loaded up and hadn't been subject to the memory leak in versions < 6.10 . I'm currently regenerating the 1:1 previews on the images in the video to see if the cache was corrupted or something. It's taken 2 hours so far, and it's at 58%. (700 images). In another 2 hours I will be able to say.
I've produced another video that shows the GPU accel colour shift and screen blackout. This time LR had been open for a few hours, so it's the absolute worst case performance. Running on 6.8 / 6.9 as 6.10 had not yet been released
Another video, this time with some diagnostic information onscreen. It's a long video as I was discussing with a reddit group ideas on how to improve performance. Skip through and you'll find CPU readouts, HDD benchmarks and some other stuff. This was recorded during a 1:1 preview generation session, which took 3 hours for 1000 images.
I've had lightroom open long enough to import 286 images and generate 1:1 previews for them. Performance is still just as bad as in the recorded videos. I'll leave it open and idling overnight to see if it leaks any memory, but honestly the concept of editing even this tiny set of ~300 images is enough to give me a headache.
Face tagging, geotagging, and all other extraneous gubbins turned off from day 1. 1:1 and Smart previews. 90% CPU over 4 cores, but no account given, seemingly, to people trying to use LR while an import is in progress. Its borderline unusable as it is (As I demonstrated in my videos) but during import - no chance. I normally leave it on overnight importing images, but this was a rush job. Rush. Hah.
At this point I was tempted to revert back to 5.7 as , although not exactly a greased sow in terms of performance, it is certainly less cumbersome than CC.
I updated the title of your thread from CC2017 (which doesn't exist) to CC2015.10.
No where in your text description (I haven't looked at your videos yet) do you mention whether going to Preferences>Performance and unchecking the GPU box improves laggy brushes and sliders. Does it?
Also, with whom at Adobe have you engaged so far and how was that facilitated? Forum? Social Media? Direct contact?
To address Rikk's comment, GPU Accel was disabled for the vast majority of the videos, as it causes strange artefacts and screen behaviour as demonstrated in video 2.
I should also add that the original videos were produced on a "Nearly Clean" windows installation - I rebuilt a new workstation from scratch to try and improve LR performance, the irony of which is not lost on me :) The installation of windows (And subsequent profiles etc) were only a few weeks old, with not much besides PS CS5, LR and web browser installed.
The Slider/Brush behavior you describe is typically GPU related which is why I am asking. My home system is very similar to yours (I have the same video card and Ram) but I don't see these behaviors. (I have GPU enabled).
If you will indulge me for a test can you:
1. Create a new catalog for test purposes and import a few of your bigger (file size) images into the test catalog.
2. Turn off GPU in Preferences.
3. Restart your computer.
4. Launch Lightroom with the test catalog.
5. Attempt the Slider and Brush adjustments that have been plaguing you.
Are you seeing similar lags in this test environment? Differences?
I started to curse Lr after version 4... I upgraded hadrware to have latest and gratest. 3 SSD's: images on one, 99GB !!! cache on another, catalog on third... I have SAME camera now for 3 years, still performance degardes. I it laggy EVEN if I go to edit thoose 3 MP files from 10 years ago. I have 2 computers with 6-core CPU, (one have HDD's and 16 GB ram, and older GPU, other have 32GB and SSD's and newer GPU), but no difference on them regarding Lr.
Sometimes (?!?) for some projects it works better, another day it is to pull hair slow. I started to use smart previews. The day I changed that setting it was FAST... ok, at least workable. But another day, same as before. Than GPU... when I enable it, Lr works better and CPU cooler is quiet, so GPU works. But Brushes are insane than. If unticked, brushes are more alive but Lr is a bit slower. I hear CPU cooler... with latest update, if I select / change 2-3 images fast one after another, the CPU works a lot, but it seems only few threads, since CPU get hot (cooler wakes) and Lr is almost unresponsive until image "loads" 100%, but only few cores out of 12 of my CPU is utilised. BTW making 1:1 previews upfront does nothing to performance.
Lr on that beast machine is almost no faster than on my 5 year old laptop with 8 GB of ram. Making new catalog for project does nothing. While exporting there is the only time whine CPU goes 100% with all 12 cores and export is VERY fast on my fastest machine and not so on slow laptop.
Photoshop have no issues, CorelDRAW/PAINT no issues and Capture One works smooth as butter. Only LR is hessitating SNAIL. Another aspect of bloated Adobe software code is Primiere, which is similar on performance and I started to thinking of harakiri. But than latest version after patches gived me hope, as I work now OK. Even I say "OK" (25 years on NLE's all from Avid, etc). So Lr need to be revamped. This is insane. We do not need ever new functions that bloats basic functions such are brushes, crop, etc... not to mention perspective correction.
This is a universally known problem. Nobody can build a computer fast enough to run LR.
I was in the same boat. Always loved LR and most Adobe software, but over the last year I canceled my subscription and stopped editing.
I won't start again until this is resolved for the vast majority of users.
Everywhere I look people with outrageously expensive computers can barely run LR (I am one of those people) and I will not post log files and pretend this is a support issue.
This is a general problem and must be addressed somehow. It has to be possible, because LR used to run better.
Though it hasn't run _well_ for years. It should feel like Photoshop. But it doesn't.
I use 2 monitors. On second monitor I have 1:1 preview selected. So I can see when image is rendered to highest resolution. It takes some time.
1) discarded smartpreviews and 1:1 previews. No image in folder selected. All images are 16MP DNG (Pentax), and already edited. All have with same preset applyd, but some with aditional brushes, radial filters and spot healing and perspective correction.
First 6-7 images needed exactly 5 seconds to be fully rendered after clicked on it. Than it was close to 6 for every image after that. Thoose with selective effects needed 8-12 seconds. I found out that perspective does not take much, most peformance hit is with brush and radial. Spot healing is slow to operate, but renders fast. What I found is that sometimes image on second monitor renders seconds after it is rendered on main window and sliders come back. Sometimes image renders much faster and sliders needs 10 seconds to show (sliders are gray during image loading).
This is not usable. If I need to load 250 images (average shootout) that is 30 minutes just to open them once. Multiply that with 10 per image during workflow that damn thing I'm paying regularly and not that little (e.g. Lr) takes me 5 hours of WAITING on average job. That means I loose 5*20 EUR (my low hourly rate) = 100 EUR / job. Thank you Adobe! I must charge more on already compating market or I just buy competition licence. Unfortunately, not using Lr does not save my bill, sicne I use Premiere which thankfully works (until next update).
2) Build 1:1 previews (in the prefferences "use smart previews" is unticked):
Images loads mostly instantly, some of them needs 1-2 seconds to render. So this is what I need. But I only tested 20 images. That means nothing since I did not test to work several hours. While image loads instantly, sliders still needs to "load": That is probably to render effects. Still this is much faster than using no previews. It takes 2-4 seconds to load sliders in develop mode.
3) Discard 1:1 previews and Build smart previews (in the prefferences "use smart previews" is ticked):
Some of images loads instantly. Most of them renders (loads) for about 2x the time as with 1:1 previews. Processor works much harders as my 1KG cooler starts to spin when working with smart previews, but is quiet with 1:1. Than another issue: Screen blackouts - some parts of tool panes blacks out. And approaching to next images demands several clicks until it goes. Even after image is rendered fully, it refuses to approach to next image and CPU cooler goes like mad. When cooler calms dow, the next image is loaded.
Interesting that sliders loads at about 1/2 the time as with 1:1 previews.
Cocnlusion: I will stop using Smartprevirews since it ruins performence, not improves it. Image loads quicker under 1:1 since it is prerendered. SmartPreview probably tryes to render 1:1 on the fly. It is even slower or similar than no previews at all. But sliders loads faster in Develop mode since effects are rendered at lower resolution file. (I guess).
Let's try the performance when tweaking the images.
The most annoying is perspective tool. The nods jumps all over so it is pain to adjust it right. Furthermore they stick to mouse and even you placed them and released mouse button it is dragged by moving mouse to somewhere out of screen. Same happens sometimes in brush editor (if GPU is selected, for shure).
Another annoyance is that on second monitor mouse click enlarges the image to 2:1, only than it is rendered to 1:1 as selected. And another click does not revert image back to FIT, but "fit" icon must be clicked, or another image selected, than it releasess it and revert it to fit.
Third annoyance (long ago noticed) is masking or brushing while having image at 100%. It is fine, until you want to move it (with hand tool, pressing spacebar), or zooming (in/out) while on brush or other selective tool. Once or twice it will do with much lag, but after few inteventions it will cease alltogether. You need to close the tool, wait until system rests, than open tool, select nod, and try again...
All in all: We pay big money to Adobe, and get this kind of software. Uggh. Sometimes I wish I would digg trenches for living, because there every shovel of dirt you lift, it is one less in the trench and you can see the progress. With Adobe software (mostly) you can see only suffer and little progress / joy. Sorry folks, that is how I (we?) see it after 10+ years with ever the same problems. New version will supposedly be better right.
Lets' try to edit some NEW previously unedited images:
Same crappy sluggish performance. Yes 1:1 previews loads image faster, but editing is a bit slower. Even paning image at 100% is laggy (1-2 seconds to move, if it moves in first attemtp) and zooming on an image still takes long. Using smartpreviews editing is a bit faster but you loose insight of image quality (sometimes I even reject image, which is fine otherwise), and image loading is double the time. So I guess I will NOT use smartpreviews from this test on. In fact...
I will not use Lightroom until this is sorted out and Adobe release new version with some "mercury playback engine" which will clain REAL TIME EDITING again.
I'm sick of wasting my life on this forums, where we chase our tails debugging something for which we pay ADOBE to do it for us. We bought tool, not opportunity to debug one ourselves. We need something that works. Something that competition already have.
I reckon Adobe gives a *** if I leave. I will still pay for compete CC for other software (that I mostly curse as I do Lr). And even if I leave completely... huge stream of new customers comes in. Lightroom is amateurish software. It is great if you only open image, apply preset, press auto upright, auto lens corection and export (to social media from Lr directly). Thoose people are slow for masking by themselves or they do not mask competelly, so they do not know it is slow. They are attracted to make panoramas, HDR's, "books", and "slideshows", use (ugly) dehaze tool ...
We need speed.
Maybe I will make comparison video of editing 20 images using Lr and other tools.

Library is on Samsung EVO 850 SSDs in RAID arrray.
Brush performance and gradient adjustments are especially bad. I often use 10 to 12 circular gradients for dodge and burn and by the time I get more than 4 or 5, they become hard to manipulate or place accurately because just trying to move them takes seconds, and the refresh rate drops off a cliff.
I have disabled GPU acceleration - but overall it actually seems worse in most other situations, although it does improve the brushes slightly.
Overall, the performance of Lightroom is far far behind Photoshop for me.
I use LR at home and at work, and specs on both systems are similar:
iMac 27-inch, Mac OS Sierra
3.4 GHz Core i7
16 GB RAM at work, 32 GB RAM at home
3TB Fusion Drive
Library is on the internal drive
Zooming to 100% results in 10-15 seconds of loading time per photo, which makes it extraordinarily time consuming to check for sharp images.
I like LR just fine, but it's slow, slow, slow. Please speed focus on speed improvements for desktop rather than adding new features for mobile.

My performance is about the same or worse running on my new machine vs. my old MacBook pro (i7 2.7ghz 16gb ram) and recently I upgraded to the latest AMD drivers and the develop module crashes lightroom. I have to disable the GPU to get into it. Before upgrading to the latest drivers the GPU would work, but the apps performance would slowly degrade over time. Here are some of the issues I've faced:
- The screen would flash black frequently .
- Sometimes when I clicked on an image, it would flash to another image first the to the image I selected.
- Using the sliders had a serious delay associated with them, sometimes not seeing the results on screen for seconds. For example, moving the exposure slider would not update the image for a couple seconds.
- Sometimes there is a 2-3 second delay moving between images in develop mode.
- Using brushes and spot removal is painfully slow.
These are just some of the more common problems. I've had other issues come up more randomly as well.
I'm going to completely remove my drivers and re-install and see if that helps the GPU crashing problem. Regardless though, even when the GPU setting is enabled, the app is painful to use.
Happy to provide any information to help fix this problem as I'm actively pursuing other apps to replace Lightroom much to my displeasure. It's an amazing app if performed well.
The GPU checkbox makes using brushes/editing an individual photo faster, but there is a delay going between images. As someone that does exposure/white balance adjusts to 90%+ of my images I leave this off to make my experience faster. Wish this could be fixed so I can have both ways fast.
1:1 gives me exact feel about image, and loading is faster and slight slower slidre response does not weight ower. Than GPU gives me faster zooming, paning, and operation. Still brush (today, I will not speak for tommorow) is not that much slower.
Zooming and pannig is smooth ONLY in main window. On second monitor GPU does not make any difference and panning is jaggy anyway.
I was so disappointed.
Had to invest in another software to sort the images as LR was too laggy. Develop module tools are also very laggy - zooming an image, spot removal, brush, you name it. At some point it just lags so much to a point I am not clear if it has crashed. Closing (killing the task in Windows) and re-opening LR helps a bit. This is on a machine with 16GB RAM, Geforce GTX 970, SSD drive. Such a shame. And the number of blog posts and articles I have read about "speeding up LR"... :/
Those complaining that LR is slow in the Library aren't building 1:1 previews or they are comparing to PM which, I believe, pulls the embedded previews not new previews based on import settings. One of the problems with LR is that you must learn all of the *tricks*. Shouldn't the software be smart enough to guide users to the best performance? Shouldn't rendering pause when the user is interacting with the UI and resume 100% cpu load when the user walks away from the computer (FCPX). Shouldn't the user be able to queue up jobs and pause them? Shouldn't the user be able to choose between precision and performance (Develop mode)?
I've got all my drivers up to date, I've got the most recent version of Lightroom CC, and I've spent 3 hours with an Adobe rep directly controlling my computer trying to optimize my settings with no benefit at all.
I HATE using Lightroom, and if I could afford to use both Lightroom/Photoshop and Capture One, I would absolutely do it.
This afinity is nonsense. I excluded half of my logical cores (so 6 instead of 12) and it just goes slower. For editing it is not much of a difference. But for creating prewiews significant. I can tell my system is fast since importing and creating previrew are really fast. Exporting as well. Just editing. And NO, I do not mean how fast image renders (that too), but I hate that sliders that used to be smooth and real time are now choppy, sticky, laggy and during changes image got blurred, panels or sliders or part of images goes blank, and so on.
Yes, developers probably load handfull of images and try them. Fine, if you trying image per se. But culling on Lightroom is not an option anymoore. You nned to switch images fast, zoom in zoom out, decide which is which, maybe make simple exposure adjustment. Sure, creating 1:1 previews helps here. But still... c'mon, we are paying a lot.
