In LR 5. Recently I noticed my processed images are sharper in the Library mode than in the Develop mode. This makes doing adjustments difficult because I can't really tell the effect of the adjustments.
PC, i7, 24GB RAM.
I've tried purging the Camera Raw cache. It's been suggested to purge the Preview cache but I cannot find the Preview cache file. It's also been suggested to clear the Preferences but those file don't show up in a search either even though my PC search is set up to show hidden files and folders.
