Hi All!
I see that the load indicator on the processor cores (CPU meter) show an even distribution of resources. But as in the past glitches in projects remained the same.
Why?

I think you need to give a little more detail about the projects that are giving you problems but it could be that you are using synth plugins which are not part of the load balancing across the cores.

OK! I understood! Very cool! I use unbalanced plugins! Bravo! Thanks!
----------------------
Is there a list of plug-ins balanced (of course, except for plugins from Cakewalk) and where can I see?
---------------------
1. If I do not work with balanced plug-ins (which obviously), CPU indicator should be showing an uneven load on the eggs .., sorry, the cores!
2. And If the CPU display shows a balanced intake, then he's lying!
Is not it so?

I think it would be easier if you were to list the plugins you are using

Slate, UAD, Eventide, Sonalksis, Ample, Vienna Ensemble Pro 5, Steven Slate Drums 4, Kontakt, MusicLab RealGuitar, VirtualGuitarist 2, Sonitus, AOM...

you probably already know this, but just to be sure, you must enable plugin load balancing by ticking the box in preferences (sorry can't recall the exact place). i myself have noticed a good increase in performance in sonar platinum since the release previous to this one, (quite amazing in my opinion) and with the latest release that certainly has not changed for the worse

Thanks The Grim. This must be done individually for each plug-in?
Or are you about it? - http://www.cakewalk.com/Documentation?product=SONAR&language=3&help=NewFeatures.002.html
But it's obvious! ))

you just enable it once in preferences/audio/playback and recording

Of course I did it.  ))

Perhaps your performance issues aren't due to CPU usage?
