Just a Test For Echo; I'm experiencing Sonar crashes when closing Nugen Audio MonoFilter4 64Bit VST3 plug-ins, especially during playback. I haven't tested other versions, since they are not installed. Anyone else use Nugen plugs with the same result? 

I do not have that plugin - but I HAVE had issues with trying to LOAD a couple of Arturia's VST 3 plugins from their V Collection.
 
I only mention that because their VST 2 versions have no problems whatsoever, but something seems amiss with certain VST 3 plugins, so maybe this is one of those suffering from some small glitch in trying to work in Sonar X3.
 
I wish I had more and better information for you - it's all I got for you.  :)

I would use the VST2.4 version until this is fixed.

I couldn't tell if it was an nVidia issue, since I don't have a reference, such as ATi to compare against, but I did find that the VST2.4 version worked fine.
