Convert that from binary to decimal (use Windows calculator) and get a mask of 85.

Thanks!
(we started with numbers 1,2,3,4 some years ago; then moved to 15 six months ago; now 85!
This is progress my friends!

I have been flying yesterday with HT = off
I must say I did not have any stutters but, I also realised I never had any stutters before.
So, I wanted to turn HT=on again and test but I also wanted to control better the use of CoD on the cores (and identify how much CPU-time is used by other processes).
Interestingly enough, I had exactly the same concern as SEE (the NV threaded optimisation usage).
