Would it be possible to implemet a triple buffer to exclusive fullscreen?

True. But implementing features in an application, although the root cause is possibly somewhere else, makes no real sense.
This issue sounds like it is related to the power settings in the nvidia control panel.
Disabling the adaptive setting and the stuttering is most likely gone.

I had exactly the same issue with vsync.
