Lightroom Classic CC Extremely Slow - Gets Slower In Use

Running Lightroom Classic CC in a Windows Environment with an i7 and 32 GB RAM is running so slow that i am seriously being hampered in my workflow. While this is not the latest i7, LR should perform better than it is. I also have SSD for main drive and for scratch disk. Theoretically, things should be better. Since the conversion to LR CC Classic, I can no longer get my work done.

I can wait seconds to see sliders react. Editing a mask is painfully slow. The lag time in unbelievable. This shouldn't be that way. Also, as i continue to process photos, LR gets slower and slower. It's behaving as if there is a memory leak. In the past I've been unhappy with LR performance, but now that LR is supposed to be faster, I'm finding just the opposite is occurring. Not only am I unhappy, I am becoming very frustrated.

Lots of little niggling things occur. Switching to the next image or zooming in, even with 1-to-1 previews created, takes many seconds, The image quality looks like it's progressively being built, kind of like a jpegs did when internet connections were real slow. The image quality gets better over 5-10 seconds. Also, sometimes, all too often, the screen goes black for a few seconds, or bright yellow polygons appear. It may be a nice light show, but what's really going on. When cropping, the previous image I was working on gets displayed for a few seconds before the one I'm working on comes back. I'm sure I could come up with other problems, but it's getting late.

Lightroom Classic CC is seriously flawed and is so slow that I am considering giving up the boat, and I've been with LR since it was first released. I will hate to do this, but I do have to get work done.

The link I gave states that the GTX 760, 770, 780 are supported, implying that the 670 is not supported.

Turning off the GPU acceleration will not help.

Yes, I do believe you need a more recent and powerful GPU.

Lr Classic, or Lr of any type, is far from "flawed".

If Lr were 'flawed' it would be so for all of us. It is not.

If Lr doesn't work on your system as you think it should the cause is either the system or the system operator.

Adobe didn't make a 'flawed' version just for you. If it works on my system and not on yours, simple logic dictates the cause is . . .

. . . well . . . You figure it out!

You are no help at all, and i don't know how you came up with that conclusion. There are lots of posts about performance problems with LR Classic CC, not just mine. Timing issues are not related to skill, experience, Anyway, I will add more information today. if you do not have any substantive information to add, please do not reply.

You are right. I had to switch from lightroom 5 to Lightroom Classic CC because I could not preview my files from a new Canon 6D Mark II. I watched videos on Lightroom Classic CC and how fast it was. LR 5 was faster. I have talked to others from the Mac and PC world that are experiencing the same problem. You get a beach ball with Mac and an hour glass with PC. For $120.00 a year I expect better.

Wow, and you obviously are an example of courtesy... Why do people get in this forums if all they will do is have a nasty attitude? Of course people will rant, Lightroom gets super, extremely slow... Let the guy find his answer, if you don't like how he is ranting, just ignore him. Talk when you have nothing good to say just takes space and is completely useless.

Mine just got really slow and I have no idea why. I installed it recently because my old one was too slow... it started up great and now again it is slow too. I will try these and see if it helps

My reply was curt for a reason. It simply mirrored your rant.

Tell us what hardware you have. Including: exact CPU, exact GPU, monitor size in pixels (not in inches), and free space left on the disk where your catalog is.

Tell us how big the original photos are from your camera (in pixels or megapixels and not megabytes).

Tell us what version of Windows you are using.

Tell us if you are doing a lot of brushing and/or spot healing on your photos.

I cannot say that I am having any issues and I use Lightroom almost daily... and it's usually not the only program I run on my MBP with 16GB RAM.

dj_paige has posed some excellent questions to you that may allow us to help you better. It doesn't sound like Lightroom itself is the issue... but, if you are convinced that it is, you might do the good old uninstall, cleaner, and reinstall.

I should add further information to my first post.

1. I started noticing performance issues with the first update of LR Classic CC. It actually seemed to work fine at it's initial release. i actually thought that it did work faster, although I never timed it. When I noticed the performance issues, I completely uninstalled LR, deleted any presets, rebooted and then reinstalled. Unfortunately, that did not fix the problem.

2. RAW file size. Typically, I am processing Nikon RAW files from a D-750 or a D-610. Both are 24 megapixel cameras.Maybe one could expect some slower response with large files. However, recently I went back and processed some Nikon D300 RAW files, which are only 12 megapixels. I have never experienced any performance issues with those files on this computer.

Detailed Desktop Specs. (My computer is certainly up to the task):

Windows 10 Pro – X64

Asus Z87 Deluxe Motherboard – Z87 chipset

Intel i7-4770K (3.5 GHz) CPU

32 GB RAM - ADATA USA XPG Gaming Series  (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 2133

EVGA GEFORCE GTX 670 –

Main Drive: Samsung Electronics 840 Pro Series 2.5-Inch Solid State Drive, 256GB

Scratch Drive: Samsung Electronics 840 Pro Series 2.5-Inch Solid State Drive, 128GB

Data Drive: WD Red 3TB NAS Hard Disk Drive - 5400 RPM Class SATA 6 Gb/s 64MB Cache 3.5 Inch - WD30EFRX – 2x in RAID 1 (mirror)

Eizo CS2739 display at 2560x1440 resolution.

3. Adobe Photoshop is not experiencing

I did notice that my standard previews were set to 1440. I just changed monitors a few months ago, and I neglected to reset the Library settings. I have reset the standard preview size to 2880 pixels to see if that makes a difference.

So, I will retest and see if rebuilding the previews improves the situation. I do find it hard to believe that this is the root of my problems, but stranger things have happened.

You have a number of problems. First, the GTX 670 is not a supported graphics card. This leads to the 2nd problem, that your 4K monitor will put a heavy strain on the CPU, and it can't keep up, causing the apparent lag you are seeing. You need a supported graphics card when you work with a 4K or larger monitor. Adobe Lightroom GPU Troubleshooting and FAQ

Also:

You haven't stated the amount of free space on your hard disk. You haven't stated if you are doing a lot of brushing or spot healing. Photoshop performance is irrelevant to Lightroom. Your previews are not the root of the problem.

Thank you, dj_paige.

Interesting comments about the graphics card. Checking Adobe, while my card is not on the "suggested" list, it does seem to meet DirectX and OpenGL specs. Direct X is 12, OpenGL is 4.6 (from specs below). Adobe says that other graphics cards may work, but they don't have time to test. So, saying the card is not supported may be a bit extreme. 

Also, when I reinstalled LR Classic CC, the GPU acceleration feature was not disabled. The documentation says that LR will disable if the graphics board does not meet spec.

I did not think that getting a larger monitor may affect graphics card performance. But, the documentation implies I may need a beefier card now.

I could disable the User Graphics Processor and see what happens.

The link I gave states that the GTX 760, 770, 780 are supported, implying that the 670 is not supported.

Turning off the GPU acceleration will not help.

Yes, I do believe you need a more recent and powerful GPU.

I'll look into another graphics card. I also have to remember it's driving a second monitor now. It's about time to build a new rig, one that can easily handle 50 MP Raw files.

Thanks for your help, dj-paige
