Disk Cache Mystery Overload?

Cubase

Hi all! I am having the most strange issue that I can’t figure out and hoping someone can help.

I recently formatted my work machine and reinstalled everything.
Everything seemed to work perfectly until yesterday, when I started getting Disk Cache spikes that would stop playback in my project.

I’m finding it so challenging to figure out what’s causing this as its quite inconsistent.
It seems that a plugin (The God Particle) on my Master channel might be an issue because when I turn it off it seems to work ok again but it had been working fine for the last few days and also for the few weeks before I formatted. And sometimes the project works fine with it turned on, so I don’t believe the plugin is the root cause.

Also, just an extra thing to note - sometimes I open the project and it works fine even with the plugin turned on. And then as soon as I duplicate a vocal track the disk cache overload starts again.

I have also run the task manager during the spikes to see if any of the hard drives might be causing this - but there are no spikes or any unusual activity on there.

Does anyone have any ideas on what I can do to figure this out ? This happens on both Cubase 13 and 14 :sob:

Here are my PC specs :
Windows 11
B550 AORUS PRO V2 Motherboard
AMD Ryzen 09 5900X
64GB ram
and all hardrives are SSD.

Thanks for reading!

You could look at the new performance meter in Cubase 14 and see if it tells you anything.

You could also check if the Latency Mon gives you any indications of possible real-time performance problems.

Hello,

Since updating to C14.0.10, I’ve been experiencing the same issue. In slightly demanding projects, the disk cache meter suddenly starts fluctuating wildly, eventually maxing out at Peak and triggering loud bursts of white noise. The track and timing of the white noise occurrences are random.

Once the disk cache meter starts acting up, Cubase remains unstable until I restart the program. It may play back at positions unrelated to the locator or repeatedly loop the same section.

I save my Cubase data on an external HDD. Changing the USB port or resetting it temporarily stabilized the system, but I haven’t been able to identify the root cause yet.

Also, in my case, an old plugin (VST2) was one of the triggers. After removing the old plugin, it seems to be stable for now.
