Lightroom Classic 8.1 latest update - Running Extremely Slowly

As per an earlier post today, I had a very severe performance problem in Adobe Lightroom Classic CC.

I have just fixed it.

I notice in Adobe Creative Cloud that there was 3 versions of Lightroom installed while I expected that only Classic CC v8.1 and the cloud based version CC v2.1.1 would be there, and not the prior Lightroom v6.

On the Lightroom v6 tab I selected uninstall - remove preferences.  Then I rebooted the computer, started Lightroom Classic and configured the catalogue and other preferences.

Everything works fine including PhotoshopCC being fast to load.   Must have been some conflict in old library files used by v6 and the latest update on ClassicCCv8.1

I too am saving the same problem with Adobe Lightroom Classic CC v8.1.  EXTREMELY slow startup and response.  It takes well over a minute to start and populate the initial screen even with a nearly empty catalogue.  There is also a significant lag (10 seconds) between keystroke or mouse click input and response from the program.  No lag in mouse pointer movement though.

Lightroom is the ONLY program with performance problems except Photoshop 2019 which also has startup problems.  All other software runs as per normal expected performance.

Lightroom is not usable as it is.  Hopefully someone at Adobe takes this seriously otherwise WHY PAY the subscription prices???

And I should have pointed to #11 in the link I provided Getting more speed in Lightroom Classic CC | DPC | Digital Photography Courses  and it comes up in others, this tip about power management OS.

Some additional tips fir performance, discussions on hard drive use and space in their somewhere

Lightroom Performance Tips - Make Lightroom Faster

Optimize Lightroom performance

40 gb of free space remaining? You are looking at trouble ahead.

You state this is a PC, and I see the GPU looks like a desktop card type as opposed to a chip set. So, not a laptop??

Do you have additional internal hard drives to start lmoving files to? That’s files, like spreadsheets, word documents, graphics, pictures.

Do you have additional hard drives to relocate the Camera RAW CACHE to, and for OS the OS scratch disk to. Perhaps the OS virtual drive, the OS temp files.

keep the LR catalog on the fastest internal hard drive, consider moving images to another hard drive.

All to make more room for programs, to make more room for images, to make more room for all the various CACH files LR, OS, and other image apps eat up.

And while we are talking hard drive space. I hope you make backups and/or copies of your catalog(s) AND your images to some drive other than C. Preferably one copy to another internal hard drive, one to a external hard drive that is connected, and a third to an external hard drive you lock away somewhere in case of theft.

And, from this somewhat limited article Lightroom Running Slow? Here's How You Can Fix It - Alik Griffin  I am reminded that a fouled up preference file could all of a sudden slow you down, amongst a hundred other things, well dozens,

Some links on resetting the preference file

https://lightroomers.com/replacing-the-lightroom-preference-file/745/

https://helpx.adobe.com/lightroom/kb/recover-catalog-images-resetting-lightroom.html

And researching another discussion I am reminded if an obvious question missed.

When was the last time you turned your computer off? What I am getting at is a cold boot, as to flush out any memory leaks.

Some people never ever turn their computers off, so this is not at all far fetched.

And when was the last time you optimizes your catalog?

Make sure you have a backup first.

Some more hopefully constructive

Check hard drive space in several areas. You stated System was working fine, then not, so some sort of change has occured. Drive space could be one.

1. Wherever you are placing your Camera RAW CACHE. How much space remaining on that hard drive. And have you perked the CACHE recently?

2. Wherever your computer OS keeps its virtual memory, the page file. Check fir space.

3. Same for OS temp files.

4. Whatever drive your LR catalog is in, remaining hard drive space.

5. You did not mention ant video work, you cannot specify where the video CACHE goes, but you can purge it as well (in preferences)

6. Software installed to cleanup temp files, cookies, browser trash etc?

7. Windows, so a lot of old trash remaining in recover deleted items?

Imam clearly missing a suspect

And now for something more constructive, as you have a Nvidia GPU

How do I customize Optimus profiles and settings? | NVIDIA

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

And that hat has nothing to do with using GPU setting in preferences

And as for in Lightroom preferences to use or not to use GPU,  well :

https://www.lightroomqueen.com/lightroom-performance-debunking-myths/

As for the DirectX status, Yes Lightroom wants to use DirectX in Windows OS, Metal in MAC OS, it runs poorly in OpenGL and in fact Adobe has a troubleshooting page that shows how to fix that. It can affect performance, but as you stated, yours is good.
