Like so many, LR is running too slow. I have changed settings as suggested by some on here, but it is still so slow I can barely use it. A month ago it was running fine. I deleted some large lcat files about a month ago, and I have a new camera, R6. I wondered if either of those things would impact LR? I use an external hard drive for my large raw files.
Because LR was running so slow, I recently updated to Big Sur ios, and I updated to the most current version of LR Classic. I even uninstalled and reinstalled LR--all to no avail. I have 119.88 GB storage available, and 3.61 to 4 GB of memory available.
