Lag when using tone curve and mask in LRC 13.

Report · Jul 28, 2024

Desktop PC: Ryzen 7 5800X, RX 6750XT, 32GB memory, Windows 11 23H2.

I experienced some lag while using LRC 13. The issue is particularly noticeable when adjusting the tone curve or any option in the masking feature. This delay and sluggishness significantly detract from my photo editing experience. However, what puzzles me is that everything works perfectly on my NVIDIA laptop. Adjusting the tone curve and using the mask are both very smooth.

I have tried some common solutions, such as disabling GPU acceleration and clearing the cache, but none of them worked. When adjusting the tone curve, it feels like I'm playing a game at no more than 10 fps. I don't know how this issue originated, but it seems to be related to a set of presets I installed. The problem I described only started occurring after I installed those presets.

Currently, I am baffled by the issues I'm experiencing with LRC 13. I would greatly appreciate any advice or assistance from the developers or community members.

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut out as that is just so much dead space to us non-Techs and it takes up vast amounts of scroll space making the reply less readable and less likely that others will bother with your post.

I finally solved my problem! I found that when I adjust the Parametric Curve it works smoothly, but when it comes to Point Curve or RGB channel the lag happened again. It was this moment that I was shocked by thousands of Point Curve presets, as shown in the picture ( they were deleted ). They were saved in C:\Users\XXXX\AppData\Roaming\Adobe\CameraRaw\Curves. After deleting all these presets, my curve works good without any lag. Hope my experience can be useful and helpful! And thank u for your immediate help!
