Question

Very slow image resizing Photoshop v21.01

Something curious:  I updated to Photoshop v21.01, and now it's curiously slow resizing images.

 

Simply resizing a  4K (3840) image to  1K(1920) using basic bicubic resampling can take 10 seconds or more - Much more if I use a more expensize algorithm live preserve details 2 or have a lot of layers in my image.

 

What gives?  I have an absolute powerhouse computer and this action was almost instantaneous (except for very large files) in the last build of Photoshop.  What are you guys doing now during a resize?

    Same problem: I'm using Photoshop 23.4.2 and using the image processor to change RAW files to smaller jpg files now takes forever. For example, 4 images took a little more than minute to complete. I have a new Mac Studio/ 64 GB RAM. I have tried severa suggestions shared hear but nothing seems to work. Also using a scratch disk. Any suggestions. Thanks

    Follow-up to yesterdays post: Today I tried the image processor function with a previous version of  PS. I used the 2021 version of PS and Bridge. Converting the same 4 RAW files to jpg took less than 10 second versus the over 1 minute with the current version of PS and Bridge, This certainly appears to be Adobe's problem and not my hardward of OS.

      Update: I downloaded the latest version of PS 23.5.0 and Bridge 12.0.3.270. The performance of the Image Processor seems to be much improved. Processing 4 RAW files took about 12 seconds versus the previous time of over 1 minute.

          I also do not see any option under Prefernces > Performance for "Legacy compositing"... but do see the message that is has been removed: 

           

          Since 2018, Adobe has been modernizing the compositing engine in Photoshop and finalized the effort in version 22.

          As of version 22, the Legacy Compositing checkbox is no longer available in the performance preferences.

            I have the same problem.  Started recently...but there is a lag of 10-15 seconds to resize, and sometimes it freezes up completely.

            I have the same/similar problem. Image resizing worked normally before last update, now it takes several seconds to "think" before it actually does anything.

            Hi Christopher,

             

            That does not sound good, as Photoshop is alow at resizing images, could you please try enabling "Legacy compositing" located in Photoshop's Preferences > Performance, then relaunch Photoshop and let us know if it helps?

             

            You may also try optimizing the preferences of Photoshop and let us know how it goes: https://helpx.adobe.com/photoshop/kb/optimize-photoshop-cc-performance.html

             

            Also, please update Photoshop to version 21.0.2 via the Creative Cloud Desktop app and see if it helps.

             

            Regards,
            Sahil

            I'm having the same problem - Legacy Compositing is selected. I can't get anything done.
