Stuttering on both Mac & PC

Hi there,

I thought before I actually jump off a building I give this forum a try, perhaps I can find a solution to the issue I’m having on my system (below):

A couple of weeks ago I started experiencing major stuttering during playbacks on my Mac Mini so I decided to test the same Cubase template (2200+ tracks) on my slave PC. I installed Cubase 10.5 on the PC and connected it to 6 instances of VEPro (Locally). Unfortunately, I’m still experiencing stuttering even on a single instrument.

The control panel window under ASIO Driver doesn’t appear when I try to change the buffer size. On MacMini I could change the buffer size from as low as 128 and as high as 2000+ but on the PC this doesn’t appear. any suggestions?

On the PC, I’m consuming about 220GB of RAM with everything loaded. The CPU load hits 99% when I do a playback but I just don’t know how to get around fixing this issue.

One other issue before I decided to test the Cubase on the PC, Cubase recognises Zen-Tour (on Mac) and every instance is connected but I don’t hear any sound. The way I fix this is to unplug the power from the back of the Zen-Tour and reboot it again. All the firmware and drivers are up to date on Zen Tour.

I’d appreciate any input anyone can have. Thanks for your time in advance.
