P: Slow Curves Adjustment layer with zoom tool selected

Apologoes for the file drill. The issue is marked fixed for an upcoming updated, not 23.1.

"Sorry, but no improvement here too. Same old super slow curves.

And adjusting mask with curves still almost not usable. Stays frozen for minutes before able to move any point. then freezes again for long time and do on..."

so I did some testing today with 23.1 and I see it is very slow on my real PSD photos but it is not so easy to reproduce that issue with new image created just in PS, after some experiments I think it is related to the masks because they make rendering slower, I will try to create video in near future with the way to reproduce that so maybe it will make Adobe interested in fixing the issue

Sorry, but no improvement here too. Same old super slow curves.

And adjusting mask with curves still almost not usable. Stays frozen for minutes before able to move any point. then freezes again for long time and do on...

please FIX!

I just tested 23.1:

- using curves on zoomed in image is still noticable slower than on not zoomed

- however looks like it is faster now (when I move point it is like 2fps previously it was below 1fps)

- on zoomed out image issue is fixed (no slowdown)

Hi all,  

We're happy to announce the release of Photoshop 23.1. This update includes the fix for this issue. To see the list of all fixed issues, click here.

Let us know if the update resolves the problem for those affected and share your feedback with us.

Thanks,

 I have an Action that creates a scenario that easily replicates the slow Curves performance. 

In the process of testing a fix and the results are looking positive. 

@J453 @Dramenon - has something on this page here been changed? Monterey, Safari, responsiveness of page is super slow. That's why I replied 2 x on Daniel's SO/rasterized question, didn't show up in my browser. My Internet connection is 300/300 Mbits - pretty sufficient so far... 😉

Hi @Dramenon , thanks for reply

1. Smart Object, lossless compressed NEF of a D850, 8256 x 5504, ACR settings AdobeRGB1998, 16 bit

2. Rasterized sent to Ps using same parameters

No difference. Slow and jerky on both, even after converting to 8 bit sRGB

Hi @Dramenon , Smart Object / Rasterized File: no difference.

Resolution of a 45 megapixel of D850 or Z7, NEF uncompressed, sent AdobeRGB 1998 16 bit to Ps when rasterized.

@Roland_RickI am familar with this issue for long, long time, I found it by doing dodge and burn under my stack of layers, so the easy way to reproduce it is just create many layers like curves/hsl/balance and then open anything like curves or levels under them, then try to move, you will notice extremely slowness, the last working version was Photoshop 21.x, it is broken since 22.x, however there must be some combination of setup/configuration which triggers that, that's why Adobe wasn't able to spot it for so long - they probably don't have test configurations to find it, after last discussions I found that it works correctly on my system if disable technology preview and use only default zoom (ctrl+0), it slowdowns when image is zoomed in or heavy zoomed out, however it is interesting that problem appears both on Mac and Windows, both on AMD and nVidia - or maybe this scenario in triggered by multiple things
