I really don't remember...it was during the Revolution lesson on merge HDR. I think Ezra had me merge three pics from his collection. I downloaded them and then "collected" them during the lesson. I don't remember the file size. I had just never seen the memory scroll across the bottom right of the Affinity window before.

In Affinity Revolution, almost done, and during the merge HDR, the computer got bogged down and in the bottom right hand corner of the screen below the CMYK %ages, I get a memory pressure (>400%) and memory efficiency of hundreds of thousands % that increase as the protocol of the HDR merge is calculating (tone, denoise, etc). It takes a long time (not nearly instantaneously) as all previous functions of the program up til now. What's going on? Do I need a more powerful computer (I have a 2013, 13" pro with one five hundred gigs of stored memory, and 8 gigs of RAM)? Or do I need to be more patient?
