Denoise taking 11 minutes per image. I need to do a batch of nearly 300!

[svree]

I've just done a job with a fairly new camera, unfortunately had flash lighting issues.
(Wish I still had my trusty Canon :l )

I've spent time already editing everything, though found many images are very grainy.

I want to do denoise on all of them, but at 11 minutes per image it will take days!
Really hope someone can help. What can I do to resolve this?

Thanks in advance!

Is the problem that Denoise used to be faster but now it’s taking 11 minutes per image, or that you haven’t used Denoise before and are finding that it takes 11 minutes per image? In other words, is the problem that the time got longer or it’s just too long to start with?

The most important question: What kind of graphics processing unit (GPU) does your computer have?

Assuming the GPU has enough graphics memory, how fast Denoise goes depends almost completely on the GPU, and also on the number of megapixels in the image.

Typically, 11 minutes sounds like it’s being done on a low-end or older GPU, or it’s a high megapixel image on a GPU that’s a few years old.

Capable graphics hardware made several years ago can typically denoise in 1 to 5 minutes per image.

The latest pro level Nvidia RTX and Apple GPUs can denoise in 10 to 20 seconds per image.
