Is this a limitation of Cubase 12.0.70?

I am using Cubase 12.0.70

51 audio tracks (28 equalizer tracks, 5 de-esser tracks)
16 group tracks
FX is one reverb send

I created the above project.
Project also loads. It also plays.
However, the orange lights for disk cache overload and processing overload come on.
Sequence start up is also strange.

I have also deleted the cache.
The SSD with the system in it has plenty of space.

Is this a limitation of Cubase?
Or my PC limit?
Is there any way to fix this?

My PC specifications are as follows

Processor AMD Ryzen 9 3900X 12-Core Processor 3.80 GHz
RAM 128 GB installed
System type 64-bit operating system, x64-based processor

Edition Windows 10 Home
Version 22H2

No stock or third party plugins used?

Which sample/bit rate the project at?

And the audio card latency?


Use LatencyMon utility to test for system and get some optimisations advices, please. Maybe this is limit of your system.

Also check the ASIO-Guard in Cubase and the Buffer Size of your Audio Device. What ASIO Driver do you use, please?

Thank you for telling us about LatencyMon.
I installed and started LatencyMon immediately.
Do I wait until LatencyMon stops?
This time I stopped in the middle of the process.

The ISR count for the kernel mode driver framework runtime is higher than any of the others at 159586 (the others are 0).
I don’t know what the kernel-mode driver framework runtime does or where it is located.
What should I do with this kernel-mode driver framework runtime?
Can you please help me?

No third party plug-ins are used.
The interface is RME’s Fireface UCX.
The Fireface USB setup is shown in the figure.

Thank you very much.

The buffer size is 2048.
I also enabled ASIO-Guard.

It can be various things actually, run cubase project and post latency mon screenshot here after 1minute. Also what is the motherboard?

Also If you have any antivirus (windows security/defender included) try to disable it for the moment, as well as disconnecting from the internet and see how it runs.

Also 2048 samples buffer is quite high, on my old 4790k(2014) don’t go there. Try lowering it.

@touchup1954 I see you have 9 WDM Devices active. Why don’t you try disabling them all temporarily? And see if ASIO performance improves a bit?

This may help

Thank you all very much.

I’ve been doing a lot of things, but it never seemed to help.
Yesterday at the end of the day, the Windows 10 update came, so I updated and closed the system.
Today I launched the problematic Cubase data and, strangely enough, there was no problem at all.
Even when I later reduced the buffer size to 128, it ran smoothly and no problems occurred.
Is this possible?

Yes, it is.
