There is no shortage of PC's at my place, but each .CR3 RAW file from the EOS Ra are just shy of 40Mb in size. So 40 of them is 1.6Gb of data...but in BIG chunks.

My older Win i7 hex core, 32Gb RAM 3.2 Ghz machine does the just the PI registration in 15mins.

My new (2019) i7 quad core Mac running Catalina, 4.3 Ghz clock with 40Gb of RAM Registered the same set in 13 minutes (12:56 to be exact)

Stacking times were about 8 and 6 minutes respectively, so sure, not a half hour for the Win machine (23 mins) and 19 mins for the new Mac.

The 6720 x 4480 pixel raw files I'd suggest are the bottle-neck.

I'd be interested to hear from anyone running the 60Mp Sony chip to see how long it takes to register 30-40 frames.
