Nuendo 12 doesn't like Dante

Using Rednet PCieR Focusrite with Lynx Aurora (n) 32channel. Something changed with the Nuendo 12 update. Previously Dante was much faster than the generic ASIO driver. But now the generic driver is about the same CPU usage as before but the Dante driver with the PCIeR card is slower than the generic driver in terms of the usage meters and dropouts. Even the VIA version is about the same efficiency as the PCIeR version.

All drivers are up to date and I am using the latest Nuendo version. Does anyone have the same results? The crazy part is that N11 is more tolerant of Dante but it still is slower than before. (but faster than N12) I know some apps resist Dante for instance the standalone version of Native Instruments will not start is Dante is the interface but it was running ok as individual plugins in Nuendo. Maybe it wasn’t tested for Dante compatibility?

What does Audinate have to say about that? Seems a driver might not be 100% with your system.

Deets on your system? Mac, PC? Did anything change in the operating system? Any settings different inside Dante Controller? Buffer settings larger?

Dante is working great for me, though i’m using an RME Digiface Dante. it’s been nothing but rock solid since day 1.

Since posting I have done a lot of trial and error experiments. With N12 on a new empty project with an empty audio track and an empty instrument track, the peak jumps up and down with 25% being the center point. Now with N11 doing the same experiment it runs about 1/2 of that reading.
On both N12 and N11 adding just one effect plugin in the audio track doubles the peak reading.
N12 will not tolerate a full project with a dozen tracks and a few plugins. Peak keeps going to redline and stopping audio. N11 will run that same project with snaps and crackles and occasional audio dropout but randomly will stop audio for a few seconds.
Now with the generic Asio driver (non Dante) there are no peaks or dropouts. I can run larger projects within limits as I would expect to have with the generic Asio driver.
I have the most recent Dante driver for the Aurora (n) Lynx. Also the most recent Dante Control app
The buffer size make no difference for Dante settings. I have ran it up to max .5msec without any change to dropouts. (normally it is set to minimum without problems- .15 msec)
I have sent a trouble ticket to Lynx support to see if they can help. I was hoping someone would be using the Lynx Aurora (n) and could share results.
This is a PCAudioLabs custom computer with i9 processor and tweaks performed by them along with the Windows10 Pro installed and Nuendo also installed by them. No problems with N10 and before just the last 2 versions have been progressively worse. Now unusable.

I found this, hope it helps:

Running N12 Dante to Avid MTRX no issues.

It’s been since September '22 when I made that original post. I had been getting by but still had issues with running DANTE which really spiked the ASIO guard and the CPU meter. I always like to follow up with a resolution when I find one so here it is. It got so bad that I was trying anything to solve the issue. I normally would not even think about installing those “fixit” programs on my studio computer but it became un-usuable even after several lengthy re-installs of everything including Windows (several times) Windows 11 upgrade made it much worse. I couldn’t imagine anything would finally fix it but I discovered something quite by accident. I looked into what was running in the background on my computer and found hundreds of services and applications. Seems like these are the normal lot of things that run with Windows. They were still there after a format of the drive and another re-install of Windows. I started eliminating groups of things thinking I would get lucky and find a fix but all it did was break windows causing another lengthy re-install. I have no idea what really needs to be there and what can be stopped or eliminated.
I tried an experiment. I found a program that claimed to stop all (and only) the junk that needs to be out when gaming. It’s for those gamers that need all of their resources when gaming. As soon as I hit the “BOOST” button, my spikes stopped on the ASIO guard. So I know for sure it was not a Steinberg issue but a background app problem. Which one? I have no idea BUT if it works like this I am happy. I know I should not need to do this but hey, if it works… So instead of trying to locate and eliminate the offending background application (or service) I can do this to save time.
I will not put the name of the program here. I do not want it to look like an advertisement. But most of you are smart enough to figure out what program this must be. So far there have been no adverse side effects. only much lower latency and CPU usage. It was the magic bullet I needed for my sanity. It may not be anyone elses issue that is experiencing higher loads in the ASIO guard so I can only say try at your own risk. Maybe someday I will find out exactly which one of these background apps or services is causing this but for now I have it solved.


There are quite a few such programmes. Some are free, such as Razer Cortex: Game Booster or Wise Game Booster. Others cost money: Ashampoo WinOptimizer or GameBoost.
Some are better than others. And some even come with bloatware, which ironically slows down your computer even more.

So if you have found a piece of software that you are sure will help with the problem you are describing, you should share your knowledge. (If you have a guilty conscience, you can also share your advertising commission with us. :wink:)

Sorry for dragging this back up again but a lot of things didn’t make sense. Although running my “secret” Driver Booster app did have an effect in reducing the dropouts, it wasn’t a permanent solution. About a week later all of the dropouts were back (with a vengence). I had been putting off replacing the expensive options for obvious reasons but after going bonkers I had to take a chance.

I couldn’t get a new Focusrite PCIEr card. Unavailable. (I have heard discontinued) So that was out. So I settled with the Marian Clara E PCIE Redundant card. This was 3 days ago. I think it has solved the issue. (even without the booster apps running) The only down side is that my Pro Tools will not accept it. No audio there but great on Nuendo.

Finally I now have audio in Nuendo even with an incorrect project sample rate. This was not possib;le before. And now when I do audio warping I no longer get the weirdness I had with the Focusrite card. I am wondering if there was a driver that I was missing with the Audinate card??

I would love to be able to use the new card also with the Pro Tools sessions that I have. Most of these were client sessions originally done with Pro Tools. But Marian says that I need an “emulated ASIO driver” since AVID doesn’t use a native ASIO format. Maybe somebody is familiar with this and can advise please?

It’s a pain importing PT to Nuendo with AAL or manual importation so hopefully I can get some kind of resolution to this…

BTW the “secret” booster was in fact IObit Driver Booster,albeit not a permanent fix
