Cubase 8.5 - CPU Drop-outs and spikes and more

So it’s a temporary work around and the program works better without multiprocessing? I will try this. I too built a fully blown system with an i7 and 24 gB of ram. I have a pro video card (for Premiere Pro) and a RME FF 400. And 5 hard drives.
Thank you for all your work into this.
