Hi Marc
I’m still exploring the frame rate with native USB3 ports throughput, as I’ve only used the ASI174MM 2 or 3 times (my ASI120MM is USB2 only).
For my Sunspot session, I saw the frame rate start at around 120fps but now that I’ve had a couple of sessions with the Moon (where I hang around the computer screen), I noticed that the frame rate starts at approx. 120 fps as the frames are buffered in memory (my Notebook has 8 Gig RAM ) then it quickly drops to between 7 and 15 fps before bursting back up to 120 fps as the “Captured” number of frames reaches the set target (say 2,000) and then it writes them to disc at 120 fps from the RAM Buffer until the “Recorded” target also reaches 2,000.
This is at the full res 1920x1200.
Cheers
Dennis
