Denoise slow after first try

[arjent75570866]

When I denoise a picture with the AI feature in Lightroom, the first try works great. The picture is denoised in about 20 seconds. After the first try however, the next picture takes several minutes. I found that when I close Lightroom and then try again, it's working fast again. This means with some projects I close Lightroom every 5 to 10 minutes or so, and that's a bit annoying. Does anyone have a better solution?

Some specs of my laptop:
Processor 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz 2.30 GHz
RAM 32,0 GB
NVIDIA RTX 3000

Is your system up-to-date, especially the driver for your graphic card.

Check if there an update available. Install the Studio version and not the Game Ready version of the driver!!

Thanks, I downloaded the latest driver now. Apparently I missed the last update. Let's see if this helps.

I probably should have checked this before posting here, but this seems to do the trick. I have now processed 5 photos and did not need to restart Lightroom yet. Thank you!

In /preferences/performance/  how large are you allowing the Camera RAW CACHE to be?

[arjent75570866]

It's currently at 5GB. Should I change it?
