Hi Billy it strange you say that about plugins I haven't heard that before. I haven't had any problems with plugins.
I had a few issues with other daws I tried a few when sonar went under. Cubase was bad I could only have one izotope breaktweaker and it was using more than half the cpu power of my old fx 8350. But I think it doesn't use plugin balancing the same way as sonar because I could 4-5 breaktweakers in one project with sonar.
