Lightroom Classic SLOW on High-End PC

I know that this is a common issue, but I am trying to see if there are any suggestions to fix it. I am using Adobe Creative Cloud and Lightroom Classic CC. The program runs pretty slow especially while using the healing brush, radial filter or other adjustment brushes. My PC Specs:

Windows 10

AMD Ryzen 1700

16gb TridentZ RGB RAM 3200mhz

Samsung 960 EVO 500GB NVME m.2 drive

Asus ROG Strix 1080 Ti

Asus Crosshair VI Hero Motherboard

Currently I have everything stock and not OC.

I have GPU acceleration on in Lightroom. Photoshop and ACR mostly run great in comparison.

This is driving me insane so looking for any suggestions.

Thanks!

Ridiculous that LR has still not been rewritten after all these years to work on modern systems. I'm about to call my clients to convince them to switch to CaptureOne with me because I can no longer go on losing money on jobs due to the slowness and lag inherant in Adobe's offering.

The last 2 updates have killed performance so badly that LR is no longer useable.

Ryzen 7 2700X PBO

I've previously posted similar frustration with the slowness of the software. Now I've upgraded my PC to 6-core Ryzen, 64GB RAM, Geforce 1070, 512GB .m2 drive on a PCIE4 enabled motherboard.

Youd think throwing all this new hardware at Lightroom Classic would make a difference, but no.. This god awful abandonware crap is still running slow as freck.

It's time to abandon this workflow and save myself from continous frustration caused by this crap from Adobe.

Recently purchased Luminar 3 and also the free alternative RawTherapee.

20 Years of using this software, I have seen it develop, I have seen it grow into the most comprehensive editing package out there

But most importantly I have seen an ever decreasing performance due to utter arrogance and complacency.

I cannot believe someone who represents Adobe actually said reduce the res, I cannot believe people are saying use a smaller monitor, for editing!!!!!!!!!!

how exactly do you see the detail on a 160mb raw file shot at 50mp on a low res monitor?????

This is a Pro package not free with someone's breakfast cereal

Hex core i7 clocked to 3800hz, 32 gig DDR 4, 500MB M2 SSD, 8gig Nvidia 1070 gtx GPU, win10 64, cache set to 100gig on a 32" or the old 24" 1440x2780 or 1024 x 1980, it makes no difference, it runs like an absolute dog, locking up, not responding again and again and again no matter what I alter,

Nothing and I mean nothing else struggles on my system, from the latest Auto CAD rendering full Architectural plans in less than 80 secs to 4k games running at 144hrz over 100fps live, Luminar had no issue, Arura no issues DXO no issue

I have had enough of Adobe's attitude, unplug everything, change everything, Why? to get one appallingly written piece of software to work half decently because they can't be bothered to sort it out

Nah sorry, remove app, cancel CC account and install one of many other options these days, Luminar, Aurora, the list goes on. I didn't want to do that because it means completely re-learning the software, but the performance is a joke

Oh, absolutely the same feelings..... I'm photographer and 3D animator; PC: 18 core Xeon, 64GB, 1070, m2, SSDs...

LR stutters, it's "not responding" at loading immages, slow to the point of making me bite my fingers - starting to hate it really, really bad!

By the way, another members non related issue reminds me to inquire

Have you made sure that some attached device, like a multi card reader, another reader, a tablet, a smartphone (apparently Android creates issues) etc. is not causing issues?

Hmm I don't have any other devices connected besides a USB C sdcard reader. Maybe could be the cause? Doubt it though

Easy to test. Just remove and see if things improve.

That monitor, connected via DisplayPort. yes?

HDMI could be wrong, well actually, would be wrong.

1. And check you various attached devices for issue. Typically detach all this devices other than mose, keyboard, and monitor, and a ext hard drive that your catalog or images, etc are on. If not used by LR, disconnect them, and see what happens. May or may not need a reboot.

Smart Phone? several members had issues with Android devices.

Ext HD not in use by LR, one user had a HD going out, could not import smoothly.

Card reader, after import, does disconnecting the card reader help

Card, typically most of us probably have LR send an eject to the card, and probably just under 100% take it out. But?

A device like a Loupedeck

Some form of tablet like Wacom

A dongle for WiFi, for Bluetooth, for authentication, etc

2. You stated not overclocking, so we can probably skip any BIOS mods.

3. Your GPU driver as provided by the chip set mfg . ASUS might have it, but who really makes it? NVIDIA?

I have what I will call high-end PC, Intel 9700K, 64GB RAM, 1TB m2 system-drive, 3 x 1TB SSD drives for photos and catalog/cache, and still Lightroom is just ridiculously slow. And now when I changed my monitor to a 5120x1440 ultrawide 49", it is worse than ever. This is being backed by a Nvidia RTX-2080 which should be more than sufficient for this.

Adobe need to just revamp the whole architecture of Lightroom, or I do not see it being used many years longer. I don't want to change at all, I love working with LR besides the slow use, but it's getting worse by the year and at some point we need to take a stand and say it needs fixing. There is no way I am moving to the shitty online version called Lightroom, if they make it like the Classic version with all the same tools, AND make it quick, yes maybe.

Thanks, but I also have followed the guides previously, I am using GFX accelerated editing (without is worse), I have 20GB cache, I optimize my catalog, I have ONLY SSD for anything I do on my computer and I do not run out of RAM as I have 64GB. The guides might help people with low end computers, but they do not change much for high-end. I also run 1:1 previews and I use Never on expire, I just add more disk instead of deleting.
It's about the application and the old architecture it's built on. Capture One (which I have worked some with, but have not changed), does not have this issue, it works perfectly quick. I am usually not one for whining and complaining, I rather buy better hardware, but at this point there is very little else to do.

This discussion is a month old and the OP has not commented in a month.

Would recommend that you start your own discussion. Include your system information in your discussion.

Would also recommend that you post your issue at:

Lightroom Classic | Photoshop Family Customer Community

(as a problem) actual Adobe techs respond in that site

Now that being said. Either your OS is not included in your comments, or (more likely) I have overlooked it. But, if your OS is Windows, simply, for now, for LR, reduce your screen resolution to 2K. No need for a separate monitor. If your OS is MAC, not much help. (With some GPU drivers you might be able to alter via properties, that setting to occur for a specific program)

Yes Adobe has a problem with LR above 3K. No LR performance does not have any relation to Photoshop, Premier, etc performance. No, just because say PS works does not mean Adobe can fix LR for this. No, we fellow members have no idea if Adobe will ever fix

I doubt you understand your own comment here to be honest. If the monitor is 5120x1440 it cannot be "reduced" to a lower resolution. Non-native resolution does not look good, and I would expect someone on an Adobe Lightroom forum wouldn't suggest someone editing photos on non-native resolution with all the negative effects it will have on image quality.

But point taken, it's the consumers job to resolve the Lightroom issues, not Adobe. One could never expect that when paying for a full Adobe CC subscription one would get a proper user experience like most other application providers give.

And yes, it HAS to to with relation to Photoshop and other tools they create, cause they show quite clearly that they can get good performance WITH image editing on large monitors/resolution, they just cannot on Lightroom.

And the OS is Windows 10, the modern OS that most users are on these days, unless they are running a Mac.

Thank you.

You don't state how large your monitor is. We need to know in pixels, not inches or centimeters.

The slow brushing and other local adjustments is a well known deficiency in Lightroom Classic, particularly if you have a 4K or larger monitor. You can try to turn the GPU acceleration off, this should speed up local adjustments. Or you can do the local adjustments in Photoshop.

Thanks! I mostly do major adjustments in photoshop but sometimes it is nice to work with the Raw file and especailly with batch quick editing stay within Lightroom.

I have a Dell u3415w 34 inch ultrawide monitor 3440X1440.

I can try the gpu acceleration off, however everything else is slow too. Moving the image around, scrolling through images, etc.

Well, that's not quite a 4K monitor, but it could be the same issue as with a 4K monitor.

Can you plug-in an HD monitor 1920x1080 or 1920x1200, restart the computer and see if the problem improves?
