Since disabling my virtual cores (only when running cubase 10.5), I haven’t had a single ASIO realtime processing overload during normal playback or live recording.
My specs, which used to be in my signature until my sig was converted into an angry protest against a pattern of dishonesty that I saw here –
Intel i7 7800x 6/12 core @ 4.1ghz
Asrock x299 taichi MB - all stock config.
Focusrite scarlett 8i6 gen 3
Cubase 10.5 + maschine2 + mk3
Akai advance 49 + vip.
Since disabling virtual cores, I’ve jammed and produced inside this environment for 1000+ hours without a single issue. However my maximum vst/fx loads are relatively low - I doubt I’ve had to load more than 10-12 instrument/instances and I run efficient send fx whenever possible. I don’t freeze or render anything until late in my process. Maschine2 makes it very easy to chain tons of fx inside each of its groups, and many factory library groups come with inefficiently routed (all individual) fx, but I’ve had zero trouble with HT disabled in BIOS. As soon as I turn HT back on, I get erratic performance/spikes in ANY project, whether I’ve got 1-2 instruments/tracks, or 10+. Makes no difference in my environment. A blank project will sometimes peak, lol.
With HT off, occasionally I will look down and see the ASIO meter indicating that it has hit red at some point over hours of playing, but usually those max spikes occurr when loading an instrument or some other process that I do not notice, but those spikes do not persist nor bother the audio outputs at all. That’s my experience anyway.
