Nuendo 6 performance - compared to Nuendo 4.3

Hello, there!

I’ve been trying Nuendo 6.0.3 on Mac OS X 10.8.0.

I opened a session I had created on N4.3(because I wanted to have video on Mac OSX), but performance couldn’t be worse. VST meter going crazy and totally “Unplayable”!

I was wondering if this is because the original session had been created in Nuendo 4.3 and there are compatibility issues or if Nuendo 6 has become such a heavy application.

I wouldn’t know if VST meters scales are the same, but N6 appears to be strainning CPU twice as hard!

Thanks for your time,


Hello Leo,

can you please let us know your system configuration and operating system?


Sure. I was just trying to figure out how to do it permanently in this profile here…

But here it goes:

MAC OSX 10.8.0
3.06GHz Intel Core 2 Duo
12GB 1067MHz RAM - DDR3
ATI Radeon HD 4670 256MB

I’ve come from 4.3 to 6.0.3 on osx and there were various reasons why I had some performance issues…

  1. Mountain Lion… some plugins were not updated properly for MT.
  2. I suggest updating to at least 10.8.2 on MT
  3. N6 is a whole new beast… and some older plugs were not performing efficiently on N6

Once I updated my "go-to’ plugins and opened old sessions, performance was at the least comparable.

However, I have to sat N4.3 was great!
