I have never had an issue with ACR before.18.3 freezing saying not responding saving files took twenty minutes instead of seconds everything was super laging, when I disabled the GPU acceleration it improved I see on the other pages I am not alone I'm using the most up to date windows, Nvidia drivers ETC: I have a 7950x, 5090, 64GB and NVME drives. Please fix as soon as possible or at least give a link to the previous version which I had no issues with.

Solution:

Update following the instructions in this link:

Try installing an updated Camera Raw 18.3 plugin and see if that works:

I’ve also been experiencing this error message since installing the latest Photoshop Beta update version 27.7.0. It happens to me when I try bring a DNG file in from Lightroom via the “Edit In > Photoshop” right click menu option.

This is not responsive. This is ten years old and somewhat before the capability to enhance the image.

Happens on all files (Sony ARW from A7Riii)

This is happening since latest update.

This is the worst. I don't know why they aren't fixing it. Shouldn't they at least roll back the update? I can't get any work done after the forced update.

It is difficult to understand how something so bad could be rolled out to paying subscribers.

I belatedly found the patch version below. If it doesn't work even after trying this, I'll be really angry.

Same for de macos version. Camera Raw 18.3 is incredibly slow. Just clicking in the Remove (B) tab takes ages. Removing dust and scratches is impossible now. I reverted to an older version (https://adobe-camera-raw.en.uptodown.com/mac/versions) instantly solved the problem. It is fast again.

Nope, i couldn’t. If i click the link with the DMG a new tab opens and within half a second it closes. No download starting here. Copy and pasting the link in a new window does the same, instantly closes and no download is starting.

You can download a .RAF file here and try : https://transfert.free.fr/C5Lbxih

I suspected there might be a limitation on the size of upscaled images, but that wouldn’t make sense. Why let the generative AI process run for a minute for nothing? It would be better to display a popup indicating that the original image exceeds that limit.

Thanx again.

@ImZeOne I was able to reproduce the error with the file you supplied, but I got a different error message.

But I downloaded some sample files from here

https://filesamples.com/formats/raf

Also from here

https://drive.google.com/drive/folders/193s1-XbxOh1Ce94thDk4SFIc71U4c88m

It works fine with the files downloaded from the above links

The message I provided was slightly different because it was in French and I had to translate it.

Note that I also have .RAF files from a Fuji X-E5, and the issue is exactly the same. I suspect Adobe may have changed the AI upsampling process and introduced a size limit, but I haven’t seen anything about this.

If that’s the case, it’s unfortunate, as running AI upscaling followed by downsampling back to the original size (or to +10-20%) produced much better results than standard processing in ACR.

Takes ages to apply new settings to a raw file. And disables my rtx gpu. Never again updating to new versions.

Yes (thank you) but why do i have to delay my workflow with every update. Should the client be the beta tester ?!

Just tested and it works correctly here (but on .arw and .dng). I’m surprised a preferences reset didn’t fix it - maybe you need to reset Photoshop preferences as well.

Can you try with ACR hosted by Bridge, not Photoshop? You do that by right-clicking the file in Bridge and choosing “Open in Camera Raw” (instead of just “Open”).

Also, try a DNG.

I tried that as well — I completely removed Photoshop and ACR, keeping nothing, specifically to avoid reinstalling them with old preferences that might be causing the issue. I also tried launching ACR explicitly from Bridge instead of double-clicking, with the same result. I tried dng too.

Thanx
