That may be a blessing in disguise. I know in Kontakt if I set the audio driver to Wasapi exclusive I get all sorts of nasty audio, but running under Wasapi shared mode all sounds are clear and pristine.
The problem is the modes and drivers are determined by the audio interface. What audio interface are you using?
Probably the s4 mk3 ;-)
Check for Windows updates including optional. There may be some for Native Instruments.
