I am having this exact same problem - I bought the HVK version of this NUC a few days ago, it all seems fine until I install the graphics drivers, then I get exactly what you describe, stuttering every few seconds no matter what I am doing. It is making this unusable!
Thank you for posting in the Intel Community.
I recommend creating a new thread to isolate you case and system configuration, please make sure you add the information of the system model and specs, detail information of the problem that you are having, plus all the information that you have added to this thread, so we can get more information about the problem.
Thank you; hope to hear from you soon.
