Test session was 24 tracks (from analog tape) at 88.2k buffer set at 64 samples. 120 instances of mono D-Verb. Im using https://www.whatroute.net/cpusetter.html to turn off hyperthreading. Will now cruise all day long at 80%+ without stopping. With hyperthreading enabled, I cant even put it into record without redlining. Distribution on processors changes dramatically between playback and record but at least its usable. Sorry about the extra text box.

Saw no performance difference with the new "Parallel task optimization" option high/off.
