Am I being throttle because of neural filter overuse?

[ultrachrome]

My company does a lot of Kodak disc film scanning and we've found that dialing A.I. "Photo Restoration" in the neural filters to about 20% to 30% to reduce grain and make faces clearer. What happens though, after a couple of dozen of images, is that filter starts running extremely slow...going from about 10 seconds per image to a minute or two per image. I then have to close the images I have open and restart Photoshop. Once that's done, I get another couple of dozen images done before this issues starts again and I have to close and open Photoshop again.  Am I being throttled because of the number of images I'm processing?

Hi @ultrachrome, thanks for reaching out! Using multiple or complex Neural Filters in Photoshop can sometimes slow things down or cause your system to throttle, especially if it's under heavy load. Even with an 8 GB GPU, filters like Depth Blur or Landscape Mixer can use a lot of VRAM, and if it gets close to the limit, your system might throttle to stay stable.
To help things run more smoothly, make sure you're using the latest version of Photoshop, your graphics drivers are up to date, and there's plenty of space on your scratch disk.
Appreciate your patience and hope that helps!

Thank you Aleke - that's very helpful because it's for this we're considering a new computer and we didn't want to make that purchase if it was throttling at Adobe that was causing this slow down. j

I wonder if Photoshop is using more and more memory, or clogging up the Scratch Disk.  

Use Windows Resource Monitor (via Task Manager > Performance tab) and see if Photoshop is maxing out on its alocated RAM?

The look at the root directory  of your primary/only Scract drive for Photoshop Temp files.  I've got an 11gb file with hardly anything open!  Remember, Photoshop is using those uber large files as additional memory, so you are held hostage to however fast your system can read and write to those files (I usually have at least two large temp files when working a project).

You could try Edit > Purge > All but IME that does not tend to win back near as much as restarting Photoshop.
