Since update to Lightroom CC Classic switching images takes 3-4 secods. if smart previous are off up to 10 seconds.
Same problem as the previous release. They didnt fix anything. as bad as always (lag). We cannot trust Adobe anymore. I think I ́ve be waiting for a solution too long and I ́ll give C1 one chance. Interesting debate topic on adobe forums "Lightroom Classic CC seems slower than previous Lightroom version it replaced"
