So, before I swap HW in my chassi (T-Minus 5 minutes..) I did a new quick .rpp with 9 Divas, default patch with some semi-random MIDI notes, identical on all tracks just duplicated.
With 9 tracks, I am pushing 75-83 'ish % according to REAPER's own performance meter and I needed to stop there (for my health)
with the Ivy i5-3570K (not OC)
If you people would just use this and see how many duplicated tracks you can pull of especially if we got/get any Ryzen users.
