Desktop PC. I9-12900, 64GB memory, GPU is an Nvidia 4060TI. All the storage is on M.2 NVMe with images on an 8 TB SSD.
Images are nothing special – I see the same behavior whether it’s a 20 megapixel image or a 50 megapixel one.
I looked through several of the topics in here (some from older versions, some from LRC13) from other people having performance issues with Lightroom 13.X. Hopefully, I’ve missed something simple, but I didn’t see much to resolve the problems.
I have to add myself to the people having problems with slow, laggy, hanging operations in Lightroom 13.
I upgraded from the AMD GPU that worked OK with LRC 12 to the 4060 TI was because once I started using LRC 13, performance deteriorated. I thought throwing a more capable GPU at the problem would cure it. Didn’t work.
It’s not a problem as near as I can tell when doing normal, “adjust sliders in Develop” or “select a keyword” sort of adjustments. But when doing things like masks, particularly brush masks, the cursor just stops and hangs for up to several seconds, then resumes. It makes getting accurate selections more difficult because the cursor isn’t smooth. Zooming to 100% to make more accurate selections makes it worse.
Similar behavior can happen when using the Lens Blur – the cursor hangs when doing Blur or Focus and when making adjustments in Visualize Depth. I also see it occasionally when doing content-aware remove, but I only use that very rarely in Lightroom.
I was also hoping for faster exports, faster 1:1 previews, and so on. Not much happened there either, but I can live with that if I can get rid of the hanging and lag.
I don’t see this behavior with any of the tools in Photoshop.
I don’t see the behavior in Topaz Photo AI, which runs perceptibly faster with the 4060 than with the old GPU.
I’ve done the “standard” things I believe. Tried no graphics acceleration – just made everything slower. And the partial acceleration. And full acceleration. The lag, hang and such is always there.
I disabled the onboard GPU.
I opened the Nvidia control panel and added both Lightroom and Photoshop in there.
I've made sure it' susing the durrent drivers. I've tried both the studio and game-ready drivers.
Are there settings for the GPU in the Nvidia control panel that can be configured to make Lightroom (and Photoshop, but mostly Lightroom) perform significantly better?
Are there other things I should try that are likely to address the problem? System configuration? Something in Lightroom configuration?
Has Adobe said anything about being aware of the problem and trying to correct it?
