Audio Performance meters are peaking like crazy at 0 load (Cubase 12)

There is a known bug where ASIO Guard gets disabled when creating a new empty project right after launching Cubase, which seems to be the case if we look at your performance meter. After fixing it, save the project and the issue will no longer be there next time you open it. That said, keep in mind that you are only using an Intel i3. These entry-level processors aren’t even officially supported by Cubase, and I highly doubt you’ll be able to achieve very low latency with these. Please try i…

Also there is a huge glitch with Multi-Processing which can exhibit similar symptoms :

Cubase multiprocessing synths unecessarily when record enabled?

While I was gathering some more data regarding audio spikes that I’m getting with low buffer sizes, I found something else that seems quite odd. When testing with only a single synth in a project, I noticed that Cubase still spreads the load on multiple cores. I wouldn’t mind that otherwise but with low latencies (buffersize of 64 here) and record enabled it seems to waste a lot of cpu resources.
