Facial detection makes Lightroom CC unusable! It is the worst POS I have ever seen! I'm on a Windows computer, 12 GB, core i7 920, 2.67 GHz, running 64-bit Win 7. I left my computer running facial detection while I was out of town for a week. With nothing else running, LR is unusable for any purpose. I MUST turn it off, but can't see how.
See if this helps you:
Go to Edit > Catalog Settings > Metadata > Uncheck - Automatically detect faces in all photos.
Thanks, but unfortunately, that's already off. The system continues to show almost 80% memory usage and 28% CPU. There's nothing running except this browser and LR. According to Task Manager, LR's process is the culprit.
I rebooted the system and it's off. Yay, and thanks!
