Why is there no better use of the CPU?
Is this an Intel, Microsoft or Steinberg issue?
Project setup:
86 instrument tracks
30 group tracks
11 FX tracks
All pictures measured at the same project part.
picture 1 Cubase Pro 13.0.50
picture 2 Cubase Pro 14.0.5
picture 3 Nuendo 13.0.50
Which windows version?
Hi Hippo,
Windows 11 pro 24H2
What is the problem? There is no need to distribute work on more cpu’s until the some are fully utilized. Is there audio drop-outs during the tests?
Hi Cubase,
At the moment I have graphic problems in the mixer. This is under investigation at Steinberg. Peaks in the threads could be the problem.
So i’m trying to get more info about this item.
Is it the same problem with all versions? I guess Nvidia is the problem…
Problem in Cubase 13/14 and Nuendo 13.
Nope, Asrock RX7600xt 16gb.
Have you tried to move the graphics to a pcie slot with lower prio?
I can try that, thanks! Let you know what it does.
Hi Cubace,
It did not work, but thanks!
this has nothing to do with your GFX card. It is the way Cubase handles projects with lots of busses unfortunatley.
I’ve posted about this earlier in the year as myself and Vin from DAWBench have been testing this for some time now and we’ve also been back and forth with the Steinberg engine team.
If you take the same project and remove the buses and put the same FX on just audio tracks etc you’ll find Cubase will spread the load very well.
AS soon as you start to use lots of bussing it seems ASIO guard gets overloaded and it will peak at 20% system useage with uneven threading as shown in the task manager here.
the only way round this is to use Audio Gridder locally on your machine and you can then load up buss FX to your hearts content until your CPU is fully utilised.
I found that this situation is a lot better on the Apple silicone machines with Mac OS, the threading seems a lot better for some reason, however I was comparing a 10 core MBP with my 16/32 thread 9950x so I’ve no idea what a 24 core Mac would do threading wise and I had no volunteers with a MAc Studio Ultra when i askd if anyone would run our DAW bench mix test.

Thanks Norbury, will take a look at it.
Audiogridder helps
placing inserts on tracks or groups didn´t make a difference for me.
