HDR Merges take much longer than previously
Before updating to LRC 15 last week I routinely blitzed through bulk HDR merges of dozens of images in just a few minutes, as well as other dng processing/import from DXO Pure Raw, and now these tasks are taking an exorbitant amount of time to complete. This is destryong my work flow at a critical time for my clients. Any help is greatly appreciated... thanks!
