Lightroom Classic M1MAX cRAW / CR3 slow and stutters

Hi there,

Thanks for reaching out. We are here to help.

Could you please confirm the version of Lightroom you are working on? Go to Help > About Lightroom or Lightroom Classic to find the exact version number for the application. Does it slow down when working with any specific tool or operation?

Please go to Lightroom Classic > Preferences > Performance > Use Graphics Processor > Set it to Off if it is on Custom or Auto. If this shows you any differences in performance, please check this article to troubleshoot further: https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html

There are a series of suggestions related to hardware & software optimization and other in-app operations you can do to optimize Lightroom Classic's performance in this article, and please give this a detailed read through: https://helpx.adobe.com/lightroom-classic/kb/optimize-performance-lightroom.html

We hope this helps,

Thanks!
