Interesting, thanks for posting about that. I have gigantic sessions with many tracks and groups and sends, most with plugins on them. In similar sessions with the same plugins (all scoring sessions, so they were setup very similarly) on PT and Reaper, there was far more CPU available and better spread across cores. That was my experience, anyway, on Mac Pros with Xeon processors. I see you’re on Windows – this thread was about OS X, so maybe there’s a difference in favor of Windows? I don’t know since I’m not on Windows.
