Performance regression browsing images on 4k monitor

I've been using Lightroom Classic for more than 12 years. I've got a big workstation with lots of CPU and GPU. Lightroom Classic worked great last year on this computer. Now it takes approximately 0.7 seconds to change photos in Library mode. I narrowed it down to the fact that my monitor is in 4k resolution. If I drag Lightroom to my second monitor (1440p resolution) the image switching performance is back to normal. If I lower the resolution of my 4k display to 1440p or lower, the performance is back to normal. This computer used to run Lightroom normally on this same display with all the same settings (same preview size, image import settings, etc). This is a performance regression and it makes Lightroom essentially unusable for my workflow culling and managing a lot of images from my shoots.

I'm on windows 11 23H2. Everything is fully updated (Windows 11.0.22631, NVIDIA graphics drivers 566.03, Lightroom Classic 14.0.1).

System Info is attached.

Try turning *ON* HDR processing (it's off by default). Completely unintuitive but it fixed my perfromance issues.

I'm using Lightroom Classic 14.0.1 (latest update) on a Dell XPS 9720 with RTX 3060 on windows 11.

I am getting around 2 minutes export times when exporting with only the CPU active.

When i activate also the GPU for export (in the Lightroom performance settings) i was expecting to get faster export times (since the cpu will have aditional help) but i am getting twice as slow times... around 4 minutes.

How is this even possibile?

Try updating your graphics driver by going directly to the manufacturer's web site:

If that doesn't help, please copy/paste here the entire contents of the LR menu command Help > System Info -- that will let us see exactly which versions of hardware and software LR thinks you're running.

Graphics Processor Info: 


DirectX: NVIDIA GeForce RTX 3080 (32.0.15.6603)

So NVIDIA GPU Driver v566.03. Two issues :

1. Fairly sure that is the Game Ready driver, not the Studio driver. For creative uses, NVIDIA reccomends using the Studio driver. The Studio drivers are more mature, they have been more thoroughly tested. The Game Ready drivers can be a bit untested, often out to make Gamers happy.

2. This particulay Game Ready Driver may have a bug as discussed in the following link:

https://www.tomshardware.com/pc-components/gpu-drivers/nvidia-reports-that-latest-geforce-drivers-ar...

Over at the NVIDIA site:

https://www.nvidia.com/en-us/drivers/

for Windows 11, and the RTX 3080, the current Studio Driver is listed as 565.90 released 15 October 2024.

You may want to remove your current driver and install the Studio driver, when doing so select a custom install as to clean out the old crud.

Not sure if you noticed but it's not a problem with the driver but with the crappy Adobe software. There is clearly a bug in the program, turning on HDR processing fixes the problem for many people.

It s funny all this Adobe Legends lol, they write aways blaming the USER or any other thing but never a problem with Adobe products. I canceled my plan because of this performance issues and when i discovered the HDR button fixed i went back to make a new plan and now they want the DOUBLE of the price for the same plan i had before. Come on adobe.

Holy cow, that worked! I would never have thought it would improve performance but it really did bring it back to where it used to be, perfectly snappy to browse images. I just spent two hours culling images with my monitor turned down to 1080, so this is great news 🙂

Thank you!

@RH_1234:,

Can you please do the menu command Help > System Info and copy/paste the entire output here. That could help understanding why enabling HDR in Library fixes some people's performance issues.

I have noticed similar behavior for some time now on my 4k monitor. The workaround I have deployed is to cull using grid mode with thumbnails dialed up as large as possible. Its not a resolution, but at least gives good performance for culling.

Hey everyone -

I'm on a 2019 Mac Pro, 12 core 3.3ghz xenon, 192G RAM, 8TB internal ssd in LR 13.5.1

At times, switching from image to image in loupe view is very slow (2-3sec, while other times it is instantaneous) and I get the message 'Loading...' at the bottom of the screen.

If I stop and do something else, then come back, it seems to be a bit faster.

I have 1:1 previews rendered for the images, and the catalog and previews are on the internal ssd.

Catalog is pretty big - 283,000 images. I have 1:1 previews rendered for only for the most recent images, but this is where the slowness occurrs. Is there a way to speed this up? Is it slow hardware? Or something in LR I can optimize? I optimize the catalog every day or so

Thanks!

Is this in:

the Library Module?
the Develop Module?
Both?

Oh - I meant Library module, not Loupe module. When cycling through images quickly to look at them. Grid module also slows sometimes. I'm trying to figure out if this is drive speed, or something else.

Thanks
