Develop Module Slow to Load Images

Develop Loupe View is slow to load one image to the next, particularly when try to flash back and forth between a group of sync’d images. Advancing through the sync’d images gets bogged down and won’t load images properly. This happens even after 1:1 previews have been created. Was not a problem in LrC v14.X

System Specs: 

LrC 15.3

Mac Studio
Apple M2 Ultra

Memory 64 GB

MacOS: 15.7.5 (24G624)

Samsung T7 External SSD via Thunderbolt 4 cable

ASUS ProArt 32” monitor 

Sony A1II or A1 ARW files converted to DNG

AI culling turned off

This is just about the best gear you can buy and LrC is the weak link…again. Please fix. I can send you a screen recording in a private format as needed.
