Windows 10 Pro 16299.309 (latest) 32 GB i7-6850 GTX-980 graphics with latest driver Lightroom Classic CC 7.2, Camera Raw 10.2 Samsung 860Evo SSD with lots of room I work with very large images, typically 470 MB TIFs from a medium format camera. LR has always dealt with these reasonably quickly, taking about 10 sec to load an image and calculate a histogram. Suddenly, it has slowed right down. It is more than minute before the image is available and the histogram shows. Most of these images have not been worked on and do not have anything in the history. Nothing on my system has changed. I have checked the monitor calibration file (fine), tried creating a new catalog, made sure previews are set to auto and 2560 )(correct native res), uninstalled and reinstalled LR, made sure Windows Defender excludes my CR cache, enabled and disabled graphics coprocessing. Nothing seems to help. LR is till taking forever to load images. ????
