Adobe Camera Raw slow with RAW files from certain cameras?

Report · Sep 16, 2024

Hello all!

So I ran into this weird problem, when I used Bridge/ACR on an older MacPro with Mojave the other day. I was editing RAW files from my Nikon D810 which worked totally fine, certainly fast enough to be a pleasurable experience.

Later I worked on RAW files off a Nikon D7100, which was absolutely horrid. Camera Raw kept slowing down with spinning beach ball and being unresponsive for several seconds. I would have assumed that those D7100 files, being smaller than those D810 files, would have worked even better and faster.

How is it possible that Camera Raw is this picky, especially when the files should have put even less strain on the CPU?

Doesn't make sense!

I hope somebody out there has an idea, because when things are bugging me, I want to get to the bottom of it 🙂

Thanks 🙂

What version of Camera Raw, Bridge and Photoshop are you using?

Oh, I couldn't tell you, as it wasn't my computer, I was travelling abroad and a friend let me do my work on his computer. I've since come back home, so I wouldn't be able to just have a look.

All I know is that it was an older version on a pretty old cheese grater Mac with Mojave installed.

However, I believe the reason for the sluggishness I expereinced on some of those files might have been the use of noise reduction, which I had applied to the D7100 files, but not to those from my D810. Apparently NR is very hungry and thus slows down the process considerably, especially on older machines. So that might explain the issue.

Thanks for your reply nevertheless 🙂
