I'm having an issue where LR Classic is running 120% CPU utilisation while idle. This is leading to terrible performance while trying to edit. Face detection is not turned on.
Troubleshooting I've done so far:
Tried different catalogs.
The result is the same. It just sits there chewing up resources and slowly eating up my RAM.
Terrible performance when you try to edit? Exactly what edit steps are the problem?
Make sure you have turned off synchronizing with the cloud, make sure you have turned off face recognition, and make sure Lightroom is not building previews. When I say "Make sure", that does not mean you state you never turned these on; it means you actually CHECK with your eyes to see that these are turned off because sometimes they get turned on accidentally.
Found it.I did some elimination testing on my plugins and found that a plugin I have for using a midi controller for editing was causing the issue. I'll close this.
