It’s arguably the exact opposite. If you have 1 track with high CPU demands then that equals 1 heavy thread. It can’t just be spread out over multiple cores if the processing is sequential, meaning that moving it to AG makes no difference. (or maybe you meant that spreading out the load was between AG and Cubase?)
But the problem indeed seems to be how Steinberg’s audio engine is spreading load over cores. When you wrote it is unsurprising that moving the load from Cubase to AG what I meant to say was that IF the audio engine was working better then it would not be surprising, because the load would be effectively the same but in different places, and therefore a lot of people are surprised when they see this because they assume there would be little difference.
I think that was my line of reasoning basically.
Perhaps we’re saying the same thing.
PS: I also think people consider the performance meter to show basically the same thing as the Windows Task Manager, and it doesn’t. That would be another reason people have “wrong” expectations.
