Cubase 13 Performance Meter Peak going crazy

[adash123]

I just bought a crossgrade to Cubase Pro 13 because I do a huge ammount of midi editing and it has exactly what I need for my workflow.
Couple days ago I started porting over some projects and all seemed fine until today when I got constant dropouts which showed up in the Peak meter.
I've been using Studio one, Ableton Live and Bitwig for years and never seen anything like it. Even happens before I load a project or when I disable all plugins.
After googling I found out its quite a common issue. But after trying every suggestion I could find, nothing is helping.
After seeing so many posts online about this I am a bit surprised really as its clearly a software issue thats been around for a bit. Its a real shame I have to spend the first days/week of owning cubase unable to use it and dealing with their tech support. Feel like I've just jumped back 10 years.

I've tried everything to make Cubase performance meter to behave like S1, Bitwig or Reaper, but without a success. In the end I just find some compromises that helps:
1. Doubled the buffer size from 64 to 128
2. Avoid heavy cpu plugins or those that don't perform well on Cubase (like Kontakt, Massive X or some Reaktor synths).
3. Ignore the performance meter!

Anyway, I noticed that Cubase performance is better on my Mini Mac M1 than my PC (Ryzen 5800x, nVidia 3070)! It seems more stable on Mac!

There is no perfect DAW! There are always some compromises. Overall I prefer Cubase on S1 because S1 is full of hidden bugs.

This is more like its causing audio cutouts every few seconds - constantly - even from the main screen before loading any projects and with alll plugins disabled the peak is constantly jumping to near max. Buffer size is already 512. Its unuseable.
Already tried adding to exclusions, different drivers (Steinberg generic versus Presonus ASIO), setting power states to maximum etc. etc.

Did you check with LatencyMon that there isn't some process or driver that's causing DPC latency?

Yes I think this is the first step. For me I don't have a problem with the DPC latency.

What kind of PC (I suppose) the OP has? If nVidia card exists, then I suggest to install the Studio Driver because in some systems the Gamer driver can cause troubles with Cubase.
