Question

Lightroom 9.2.1 general experience slow

I did some searching and could not find a suitable solution so here goes.

Specs:

AMD 3950X

64GB RAM

GTX1080ti

Multiple PCIe SSD 2TB + 1TB etc (Plenty fast space)

I mainly import RAW CR2 files (50Megapixels) and do Basic adjustemnts with some brush spots. Nothing major. (Possibly 50 photos at a time with roughly 2 - 4 brush edits per photo)

I have worked through all the online tips incl:

Optimize catalog

Clear cache

Re install Lightroom

GPU accelerayion is ticked

Cache size allocated 100GB

Previes medium and delete every 30 days

GPU, Windows, CPU drivers are all up to date.

Create new catalog and start over.

The general interface is slowwwww. Making adjustments to an image takes a few seconds to respond. Everything is just very laggy.

Any further help would be great.

Thanks

GTX1080ti

so NVIDIA GeForce GTX 1080ti, what GPU driver version? What does System Info in Lightroom Classic (/Help/System Info) tell you?

Have you used the probably installed NVIDIA utility Geforce Experience to check?

Per NVIDIA, latest is v446.14

Adjusting res to sub 4K sounds like a plan too, will try this out. Thank you.

I have no idea on that

Since you appear to have MS Windows OS based on rig, try, as a diagnostic, or temporary workaround, decreasing monitor resolution to sub 4K, adjust standard preview size to either automatic, or something under 2K as well.

Issue could be Lightroom Classic having to create all those pixels over and over again with is develop edit, especially when you get into adjustments.

A common complaint. Large MP files, with local adjustments --> laggy. You don't say what size your monitor is (in pixels), could you provide that information please?

Also, local adjustments will be slower when you have the GPU acceleration turned on. Please try it with the GPU acceleration turned off.

Thanks, my monitor is a 4K 32 inch.

I have tried gpu accel off. no difference.

My assistant's machine is a 9900K with gt1070 card and same screen. Same LR settings. no problem there...

So weird...

Yeah, same project same adjustments.

We use Bitdefender on both machines. I can't find any specific way to tailor Bitdefender in this regard...?

Just funny that the 9900K machine works effortlesly.

There is "Manage Exceptions" in the Bitdefender AntiVirus panel.
