Question

Lightroom became extremely sluggish and uses a lot of CPU

I didn't really change anything recently, but now lightroom is really sluggish for any operations that are changing the viewport.

Lightroom classic, the latest of the '5'.

For example, I just changed cropping, then clicked reset, and lightroom.exe was "frozen" and "not responding" in the task manager for the last 1-2 minutes, consuming a lot of CPU (2 cores or so)

I have plenty of RAM available

I tried upgrading NVIDIA driver for my geforce 1060, it did not help.

And here is the CPU usage, most of it is lightroom

As I finished writing this post, lightroom is still non-responsive.

Any ideas?

And two tips that relate to outside of Lightroom

1. As you are not on a laptop, nor, apparently a all in one (heat concerns, power concerns) and you are using an NVIDIA GPU, see:

https://www.winhelp.info/boost-lightroom-performance-on-systems-with-nvidia-graphics-chip.html

Note that the above setting used to get reset to default upon GPU driver update

2. And for Windows, see tip 8 in:

https://au.pcmag.com/windows-10-1/5180/11-tips-to-speed-up-windows-10

Note, the above setting, often gets reset to default upon OS updates.

So, first some observations from your Sys Info

Lightroom version: 5.7.1 [994254]

Well not get into that ancient version in terms of moving on to subscription, but v5 will enter in to one issue below

Operating system: Windows 8.1 Business Edition

Unfortunate that, probably the worst MS OS, causes lots of issues. But to fix will probably involve a new rig. I assume your rig does not support MS OS Windows 10, or else you would have moved to it long ago.

Processor speed: 3.5 GHz
Built-in memory: 32700.1 MB

Or, perhaps you can move on to Windows 10? Why not?

Displays: 1) 3840x2160

Ok, so the reason I brought up v5. I do not remember if in v5 an option in /preferences/performance/ existed for use Graphics Processor, does not matter because I know in v6, it exists, but is useless, it did not work. Does not matter how nice your GPU is. Lightroom is a Parametric editor, not a raster editor, every develop edit you take causes LR to recreate each and every pixel for that 4K screen. In fact LR starts at your first history state, works thru all the history states, recreates pixel each step of the way, eventually working thru all those states and presents the new develop preview (and rewrites library previews) So, decrease your screen resolution, and adjust standard previews as appropriate (auto works nice)

Thanks David for your response.

Just to clarify: I am on Windows 10 pro. It seems that Lightroom is misreporting the operating system 🙂

From systeminfo:

OS Name:                   Microsoft Windows 10 Pro
OS Version:                10.0.18363 N/A Build 18363
OS Manufacturer:           Microsoft Corporation
OS Configuration:          Standalone Workstation

> I do not remember if in v5 an option in /preferences/performance/ existed for use Graphics Processor

It doesn't 😞 I already looked for that.

And to clarify: this is a regression 🙂 I've been having the same OS and Lightroom for many years now, and I never saw such freezes. After I changed the directory, the freezes went away. I will try again going back to the directory that has issues and will report back 🙂

How many hard drives do you have, are any of the SSD?

Some performance points

1. The catalog benifits from being on a faster hard drive

2. The Photographs do not benifit from being on a faster hard drive

3. The Camera RAW CACHE can benifit from being on a faster hard drive

4. The Camera RAW CACHE should if possable, not be located on the same hard drive as your Windows OS Paging file, as they will comoete for hard drive read/writes.

5. The Library Previews must be with the catalog.

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

1 more observation: it seems that after I switched the folder in LR to a different one, it came back to life and started being responsive again.... Which is interesting, since the one I was editing wasn't even having many pictures (but it had some videos).
