Hello!
I know Lightroom speed and performance issues are not new here. Still, I am very frustrated and looking for help. I have a brand new Mac Studio M2 Ultra with 128GB RAM (60 core GPU). Specs below. My library has ~11K photos. I am using latest version of Lightroom CC. Local storage for all orginals and smart previews is turned on. Graphic acceleration is fully turned on (I've also tried turning GPU off per other threads).
Despite all this, Lightroom is lagging to the point of being almost unusable.
Specifically, I face serious issues with:
-Switching between photos in gallery (can take multiple seconds to switch, then multiple more seconds to fully load the preview)
-using masks, opening masks, turning on/off overlays, etc
-these issues are especially exaggerated when I'm using AI masks (subject/background/object); even just one 'subject' mask seems to take performance down significantly
Not sure what I'm doing wrong here. Should I move to LR classic? I've experimented with that but doesn't seem to help much. Weirdly, the iOS app seems to be much faster and doesn't face these issues. I don't get why my brand new $4500 PC should be worse than an old iPhone...
Thanks for any help 🙂
