Is Lightroom Classic significantly slower than when it was just called Lightroom CC? I recently built a new computer with a Ryzen 1920x processor, 32GB RAM and dual Samsung 960 Pro SSDs. I also updated Lightroom to the newest version (Lightroom Classic) at the same time. I expected it to scream but everything about it seems much slower than it was on the four-year-old laptop I replaced. Building 1:1 previews for a couple dozen large TIFs has currently been running for 7 hours and is only about 1/3 done. While LRs processor usage is under 5%. The interface is incredibly slow too. Changing modules takes a long time. Grabbing a crop handle will take a few seconds to start responding. The whole screen will occasionally go black and show me the busy spinner. Nothing loads any faster than it did on my old laptop; maybe slower.
What gives? Is Lightroom bottlenecked by it's own code and simply unable to take advantage of fast processors and SSDs? Or is something wrong with my computer? PT GUI and Photomatix both seem much faster. Photoshop too but I haven't used it much yet. It's frustrating to have spent this money on a powerful computer only to have LR act like it's running on a out of date budget PC.
