2990WX/W10 scheduler problem

Here is an interesting article on the latest W10 scheduler problem.  MS is working on a fix.  It provides a link to coreprio.exe (free utility) which is a temporary (and probably flawed) workaround.  I have tried it with significant improvement in Indigo Supercar Bench of about 65% (4.325 -> 7.254).  There was no improvement for the Bedroom Bench).  It did not help Cinebench.  All these test saturated PPT and TDC and I had to raise them to get these numbers.  Here is a screenshot of Ryzen Master:

Using this RM 'CB Profile', CB score went from 5040 to 5724.

I found in ryzen-master-quick-reference-guide.pdf this explanation for the '--%' always showing for EDC for the 2990WX:

Any questions/comments?  Enjoy, John.
