Using updated LrC CC for 13 NEFs from Z7, shot handheld.
It's been cranking for over an hour now and the status bar isn't even 50%.
This is on a 2017 iMac with i5, 24 GB of RAM, Fusion drive. The RAW files are on an external USB 3.0 drive.
I've been using Pano merge since it came out a couple of years ago. It's progressively gotten worse in terms of time it takes to complete the merge with each successive CC release. More failures than there used to be as well.
I will also say the performance was much better with D750 NEF files.
But while this merging operating is going on, it pegs my CPU. Yet the resulting pano DNG files are several hundred MBs at a minimum and often over 1 GB. The individual NEFs are around 60 MBs.
So how does this get improved, all SSD in the chain? Upgrade to an ARM processor Mac? Switch to Windows with some $1000 graphics card?
Obviously prefer to merge in LrC. But I swear, I could send my NEFs to a dedicated stitching program, which I haven't played around with in a long time, and get the results back and re-edited in LrC much faster.
Got to be faster than going for well over an hour (and running, though I wouldn't be surprised if this merge operation fails).
