Upgraded to Mac 12-core, have same ASIO/CPU in Cubase

Huh. Well I recently came from Pro Tools (and sometimes Reaper) to Cubase 8.5 and immediately I noticed that it got knocked out far earlier than PT would. I’m sticking with Cubase in hopes that this issue is improved (hopefully in C9), but it’s a very real thing for me. Same computer, too. Last week I tried what someone suggested on another thread and I recreated a Reaper session to mimic a very large Cubase session exactly, since those programs both use the same VST’s folder. For me the difference was night and day, where Cubase was overloading and stuttering on playback with dropouts and Reaper was hovering at around 65% with no dropouts.

As I said I (would like to) stick with Cubase, so I hope whatever is causing this for myself and the other users here (seems to be both on Mac and PC??) gets fixed. I have a 6-core 2014 Mac Pro.
