8 Seconds to switch between images

[emrosedee]

Oh my goodness. I want to bash my head in. I'm 100 photos away from finishing a wedding, and Lightroom is being so so slow that I can't even stand to work in it right now. I've tried adjusting preferences, upping cache size, disabling parallel previews, turning GPU on and off, resetting all preferences, using only Smart Previews, etc. All it's done is make it even more sluggish and given me more grief with editing. It takes at least 8 seconds to switch between edited images, preview presets, and forever to sync edits...I just want to rip my hair out!! 

Here's my computer stats:
Processor 11th Gen Intel(R) Core(TM) i9-11900K @ 3.50GHz (3.40 GHz)
Installed RAM 64.0 GB (63.6 GB usable)
System type 64-bit operating system, x64-based processor

Edition Windows 11 Home
Version 24H2
Installed on ‎2024-‎12-‎17
OS build 26100.4946
Experience Windows Feature Experience Pack 1000.26100.197.0

And I'm running Lightroom Classic 14.5.1 that just updated today. I feel every update makes it slower and slower. With 64gb RAM, shouldn't it be pretty fast?! What am I missing?!

What type of drive is G:? How is it connected?

[ShootingPixelsAndy]

It's 2tb M.2 used only for LR catalogs, plugged directly into the motherboard.

That's the same drive setup I have in my Win 11 machine. It should be very fast.

Is you antivirus set to ignore LrC?

[ShootingPixelsAndy]

Yes, have also tried disabling the AV completely with no luck. Have you watched the video I posted?

Another observation. When I switch images a spinning icon often appears on the right hand side of the toolbar below the image. If I hover the mouse pointer over it it says GPU Rendering but this doesn't seem to be the case. The attached video shows that the GPU is mostly idle but the CPU and DISK seem to be a little busy.

Do you have a different GPU that you can use for a test?

[ShootingPixelsAndy]

I don't but I see the same issues on my laptop (but worse as it's not as powerful with its RTX3050). The issue definitely seems tied to images with AI masks that's the only time I see it happen.

I worked with a RTX3050 on my Windows 11 machine and don't have any issue with AI masks. It works as it should and with a good performance.

On your laptop it can be that you have another issue, the internal GPU. The internal GPUs of the buildin CPU can caused several problems in Lightroom and Photoshop. So I would try to disable the internal GPU. 

Open the Windows Device Manager, right-click the card's name and choose Disable.

Thanks for the suggestion but the mobo GPU is already disabled and the issue on the laptop is with the exact same images I have problems with on my desktop. And, no, they're not from a network or external drive, the catalog and images were copied across to the internal m.2 drive on the laptop.

Just to be clear, creating the AI masks isn't the issue, it's switching to images that have an existing AI generated mask and especially those where that mask has been intersected with another mask, say a linear gradient.
