latest Win10, latest V2, latest Nvidia drivers
Focus stacking in V2 is horribly slow compared to V1 - watched Task Manager and Resource Monitor trying to detect why is it so slow
First is disk reading - V2 starts less then 10 instances and read disk very slow - max at 5Mbit/s of only one picture, other threads are much slower - even 40k/sec
V1 starts more then 30 (maybe even 50) instances and reading goes up 20Mbit/s at fastest threads
180 50Mb BMP files V1 reads, I would dare to say, at least 10 times faster then V2 reads 120 of them
I estimate that just loading of 120 BMPs in V2 takes more then a half an hour and then alignment and merge starts (also with much less instances then V1)
In V2 alignment/merge processes are also slow - using also very small number of threads/instances of photo and system.
