Previous version of Lightroom was fast. This version... slow. All dialogue boxes are slow.
The develop panel and the folder panels are sluggish, taking around 20 seconds to respond to open or close.
Viewing Activity Monitor, LR is taking up 85% - 92% of my CPU.
I always have to Force Quit to close it.
Overall, you've killed my workflow. I can't continue to work in the environment. I'm now trialling Capture One.
