Hi, I found that since the recent update (9.12.1) the image quality in the ACR-windows ist really bad.

The quality returns to normal, by selcting the GPU-accelaertion to off...

 

GPU-acceleration ON:


GPU-acceleration OFF:



The image looks like shot with ISO12800, but its shot with ISO200. And the rendered image is good as well.

As a result of this issue the "Visualize Spots" tools is affected as well, because due to the grainy picture, real spots are "overlaid"...

 

Regards!

Just checked this on my system Mac OS 10.12.6 and Camera Raw is not exhibiting this issue on my system, Possibly a bug Windows specific problem? Can anyone else confirm?

With ACR 9.12.1 on Windows 7 I see no difference in a similar raw image file.  There's nothing in this update that should affect GPU operation. Just new camera and lens profile support and fix for a Canon 6d Mark II camera issue.

I suggest you try updating the graphics driver on Nvidia site: http://www.nvidia.com/Download/index.aspx

http://blogs.adobe.com/lightroomjournal/2017/09/camera-raw-9-12-1-now-available.html

The goal of this release is to provide additional camera raw support, lens profile support and address bugs that were introduced in previous releases of Camera Raw.

Thanks, I use the actual Nvidia-Driver (385.41).
I can assure this came up with the release 9.12.1.

Please investigate in this issue!
I have to disable the GPU-Acceleration, but this slows everything down.

Graphics drivers are installed in Windows and OS X updates or manually by the user. They are not included with ANY Adobe software applications. Can you upload one of the image files with this issue to Dropbox to see if the issue is reproducible on my system?
