I've used it enough and I watch it that this has spiked to about 10x it's normal use. Anyhow I'm a little hesitant to upgrade things but it said it had a lot of good new features so I did, now my CPU usage is upwards of ninety percent plane very very small even self-made 3 sample instruments.
I just upgraded Kontakt for the first time since owning it, I installed it when I purchased the bundle about a month ago.
