I ran artisan-west's 01714.jpg on my desktop computer 16Gb, i5 CPU, Win 10 latest.
GPU is the RX580
I ran on v188.8.131.52, same settings noted in post above on this thread.
Time to Blue Bar 4min 49 seconds and 5min 15sec to the Check Mark.
I have also run several images off fB (.38MB to .42MB) to 10 inch width, 16 bit, moderate, TIFF and they run in 30 seconds or less. Make great prints 8x10 inches.
Thanks for this thread. Great program.
