Nuendo 13 Audio Performance for Sound Design

Hi, I was having some issues with the audio Performance in Nuendo 13 with even very simple Sound Design Sessions. Yeah, I work with high sample rates and yeah, I need to stack up a lot of plugins for processing in my sound design workflow. I’m on Windows 11 Pro, I’m using an AMD Ryzen 9 5900X on an Asus ROG STRIX X570-F Gaming Mainboard with 64 GB DDR4 3600C18 RAM and a Geforce RTX 3080. My Audio Interface is an RME Fireface UFX III. I have the buffer set to 1024 Samples, activated the “high” setting on ASIO guard, and I’m using the Steinberg power scheme. Is there Anything I can do to increase performance? Or should I get a new CPU+Main board at this point?
In the case that I would need a new CPU: What would be your recommendation for my kind of sound design workflow? I also noted audio drop out with Phase Plant patches played at high sample rates if I press more than 1-2 keys, which is also pretty unacceptable.
I would appreciate any tips on how to get a nice performance with Nuendo, what CPU to use and if you have any other tips where this kind of questions can be answered.

Thanks in advance
Daniel

Hi Samllvillee,
I know Steinberg has an issue with spreading the workload over your processor cores. See my point.

Steinberg is working on it. For the time being you can “unpark” your processor cores in Windows. If you Google this theme you will find ways to achieve this. This might help. Good luck
