I normally use Ozone and other Izotope tools, and I love them. They are supposedly CPU hungry, but my system runs well on them. However, the new Sonar mastering tools are completely unusable on my system, causing playback to stutter, lag, and get out of sync. Deleting the instance of the plug-in eliminates the problem.
 
Anyone else finding this to be a problem? I'd like to try and use these to see how effective they are, but I can't and I don't remember ever having a problem with a Sonar update or Sonar effects before.
 
 

Have you tried increasing the buffer size for your audio device? Do you still get problems if you do? 

I am having exactly the same problem with the new plug ins.  They cause shuddering during playback and drop outs. Like yourself I have never had any problems whatsoever with any sonar Platinum upgrade until this one. They look good and I would like to give them a try but at this time they do not work. Up until this new upgrade everything has been excellent.  How about some help here to get these things fixed.

"nonlinear" worked for me, this was when I was using Addictive Drums, would drop out during a pattern play back. Review the first link above.

Non linear or low are all I can get to work here without stuttering.

Not exactly the point of a linear phase EQ. 

The suggestions above have improved the situation, and in some cases solved the issue. But seriously, I'm not sure I'm going to use those plug-ins, when I already have equivalent types of tools, such as Ozone, Alloy 2, etc., etc. Frankly, this is the first time I've had a new "house" plug-in cause a system problem. I wonder if anyone else is less interested in the built-in stuff offered with both Sonar and all other DAW's. There are so many good plug-ins, and while it would be nice in theory not to have to purchase as many 3rd party products (especially given the reasonable pricing for existing members), at this point I am less interested in having my DAW include tons of plug-ins and instruments, and simply stick to what they do best--a recording and editing platform. A "slim" edition with the cababilities and engine of the "bundled" version might be more cost-effective in the long run, as I have so many built-in options in Sonar that I simply do not use.
That being said, I love the ProChannel console and emulations, etc., but I could certainly live without them and use 3rd party solutions if it made the DAW simpler to use and less $$, too.
Not exactly a rant, but just a growing feeling that sometimes more is not always better...

I think you just invented Sonar Artist.

LP MB AND LP EQ ARE THE BEST BY FAR AND BEYOND > but I can't use more than one instance of each without a project crash ! I truly hope when they fix them that we don't lose there soul because WOW .
