note the date: https://community.adobe.com/t5/lightroom-classic/lr-cc-very-slow-on-hi-end-pc/m-p/10710207#M161896 My PC: i7 6700k, 32GB DDR, Samsung SSD, GTX 1070 Windows 10 Lightroom is very slow at basic tasks like select images, change module, write caption title etc. Can take up to 10 seconds just to select a few images. small jpgs as well as hires raws. LR freezes for some seconds (not responding). What I have tried: uncheck/check gpu acc. reset preferences. removed all plugins disabled all plugins uninstall and reinstall LR made a new catalog with just 130 images. Same response as catalog with 100k images. When browsing images, the cpu usage goes up to 10-15% It's been like this since last fall when I built this PC. On my macbook pro 2011 it is just regular slow. Not ridiculous slow like this. But tasks like editing images with the sliders in dev module, import and export seems to run like normal.
