Used a stopwatch to know how long it take to stack 3 DNG files from the Pentax K1 (without alignment). But processing speed is not a problem in my own case. Hugin may align handhelds a bit better though I haven't had a chance to really learn the new Silkypix options yet. I'm completing the entire composites (strobe/moving object removal) in under 20 secs. Just checked by taking 3 shots out my front window at cars going by handheld. I have a 2-ish year old homebrew desktop (12-core Ry 3500Mz) and a 4 year old top-of-the-line Asus ROG (semi-)portable running Windows on an 8 core i-7 Well top-of-the-line 4 years ago, anyway. I don't know what computer is needed, unless the software coding is not efficient for the kind of task.K-70 user in my case. When I tried with alignment, I waited 5 minutes (application not responding), the application hanged and I had to stop the application using task manager. The RAM is only used to about 50%, not SSD swap involved. It takes 1 minute 20 seconds with a 8 core processor 2GHz and 16Gb of RAM.
