What are the USB chipsets on your board?
Which are your sensors/HMD connected to?
Is the same behaviour experienced with fewer sensors attached?

It makes me think of this recent article by Bruce Dawson:

Windows 10 has a bug where the more cores you have the worse performance can become if you do certain workloads (in his case lots of process spawning), to the point of his 48 hyperthread xeon barely moving the mouse. This is because every thread was bottlenecked waiting for a global lock.
Might not be related, but who knows.
Try setting the process affinity of the oculus stuff (home, etc) to less than the full number of cores to see if that helps (process affinity is an option in task manager).

I tried to find any reports of Vive performance with threadripper, but I didn't find any (I also didn't try for long).
I'm planning on getting a 1950x, so I'm definitely interested in seeing what's up here.
(I do non real time graphics work, genetic algorithm and neural network training and c++ compiling, all of which benefit from lots of cores)
A shame you can't install win7(or Oculus had Linux support....) to see if that win10 serialised process destruction bug is the cause.
