I run LINUX MINT 22.1 Operating System with Intel i7 CPU. The computer has 32GB RAM and I enlarged the SWAP File to double the DRAM size - 64GB. Polyphony is set at 3600. I currently keep up and running five simultaneous different Sample Sets so I can pick and choose ranks or aggregate the organs. No problems unless I go overboard with multiple TUTTI's and play too fast with big chords. None of the problems you mention. If I go overboard I'll just get some CPU cutouts, but that's my stupid fault.
I am more than ever convinced that LINUX is the superior OS for GrandOrgue and that it manages memory more efficiently. Here's a screenshot of the computer's current state with five big organs loaded:

And you can see the simultaneous GrandOrgue loads -

LUDGERUS-Rotterdam, Friesach6Manual,Utrecht, Rotterdam-Caen5Manual, and SolinaStrings.
Purists may protest, but in the final analysis the ear is to be pleased without regard to rigid tradition.
