With 10, I am having the same issues. 17% CPU load, with 6 heavy (Maschine, 2xMassive, 2 Omnisphere, and Minigrand) VSTs and only 5 light plugins.
I just dont get it. Might have to redo my entire Hackintosh setup, reinstall everything and start from scratch, see if that fixes it. Might go Lion while I'm at it.
Hope not
