I’m having problems with Cubase 14 on Windows 11. When it spikes it’s a loud beep.
9 audio tracks, 1 VST SSD drums. So a small project.
Other projects run better than this one but audio performance changes for no apparent reason. Sometimes I can run the session without this happening, other times I’m frequently interrupted by audio beeps. First screenshot, everything running perfectly, second screenshot, it falls apart
Have you tried running latencyMon to see if there is a dpc problem. What about background tasks? Have you checked if something else is causing this? I always pause windows update if I’m doing something important. Then there are all the windows tweaks (search windows tweaks for audio) that can help.

Sorted it. Turned off “”record” on the 1 midi track and I’ve been happily using it all morning, no glitches.
What a strange thing that simply enabling record on a midi track sends Cubase reeling. I watched the change in audio performance in real time as I switched record on and off. Thanks for replying
That is perfectly normal, if the MIDI track is connected to a VSTi. Enabling record (or monitor) on a track moves it from ASIOGuard engine with its high safety buffer (>2000 samples) to the realtime engine, which runs at whatever buffersize you have configured with your audio interface. If the overall load is already high, that can result in dropouts, especially if the VSTi in question is rather demanding on the CPU.

You can actually see it on the meters in your two pictures. The first shows the load on ASIOGuard only. The second shows the load moving to Real Time and Peak once record is enabled.

Seems obvious now I know 
but I’ve spent about a month refreshing drivers, reinstalling VSTs and generally pulling my hair out. I have a project ready to mix, 8 audio stems and 1 midi drum. Everytime I clicked on the drum pattern to edit it, I was arming the record button, not because I wanted to record, just to edit the drum map. That sent my audio performance into a frenzy. Just feels to me as if this should be easy to find information. Thank you again for your help
It does mean your default audio settings are too aggressive or otherwise incorrect for your setup and audio interface.
You should be able to record just fine. ASIOGuard just gives you additional safety.
