Does the efficiency of AI denoise decrease when used on a sequence of thousands of images?

[lingjie368158042wwy]

Hello Adobe technician, I have encountered a problem when using the AI noise reduction feature in PS and Lightroom. When I am doing time-lapse photography and applying AI noise reduction to a sequence of two to three thousand images, the efficiency starts off very high. However, after a period of time, the work efficiency gradually decreases, and I notice that the intervals of GPU operation are getting longer. Only by restarting the computer can the GPU operation intervals return to their initial state, but the intervals will gradually lengthen again afterwards. This issue occurs on all three of my computers.

I would like to ask what might be causing this?
Are there any ways to improve this situation?
Additionally, my motherboard supports multiple graphics cards, so how can I increase the efficiency of AI noise reduction?

thanks

Have a look at the root directory of your primary Scratch drive.  I'm wondering if the Photoshop Temp files are building up?

What you could do is make an action that runs deNoise and then goes Edit > Purge > All and then batch the images using Image Processor running the action.  I don't this is what is going on, but it seems like a reasonable first step to trouble shoot the issue.  

Note:  I am not sure that Purge with clear the scratch files, if that's part of the problem.  the only way I know for sure to do that is to restart Photoshop, which is obviously impracticle.

Denoise runs entirely in your GPU. I don't think it touches Photoshop's memory management since it's not system memory, it's VRAM. If paging memory, it's probably operating system paging.

In any case, monitoring disk usage should be straightforward.

My first thought was heat buildup throttling it down, but I see it's steady at 74-75°.

Do not use multiple GPUs. Supposedly it will work if the two cards are identical, but it will only use one. Read this first:
