NX Studio 1.70 & 1.80 are very slow fetching files across a network, and on Win11 just useless for anything not on the local computer.
I'll do a test install of 1.90 on Win11 to learn whether Nikon (or Microsoft) have got their act together, such that remote storage can be use. My hopes are not very high, though. Win11 is very buggy under its slick surface. Perhaps Win12 will clean up all the bugs?
NX Studio not only constantly scans all files in the current working folder, but also folders previously accessed by other applications. I caught NX Studio reading my accounting folder on the NAS even though I was opening a picture folder on the SSD.
Microsoft Sysinternals' ProcMon (to be found on microsoft.com) can be used to log NX Studio's activity. Then you understand why it's so slow. With only a few files on a fast SSD, this isn't noticeable. But when a folder containing several hundred images on a NAS is constantly being scanned, NX Studio can't do anything else.
To increase the speed of NAS access, Nikon wouldn't have to do anything—on the contrary, they would have to do less. It's sufficient to generate thumbnails of the images currently displayed in the browser window. Loading an entire 45MB NEF file into RAM takes less than a second over a gigabit network. Therefore, it can take a maximum of one second longer than from an SSD. The problem arises when the program attempts to generate previews of thousands of images. A thousand seconds is an incredibly long wait for someone who only wants to edit a single image...
