My Experience.
Well, a while back I had been using the shortcut method to set affinity.
For a while now I had stopped using that shortcut.
A while after you posted, after researching and noting the concerns posted, forewarned about possible issues, I tried your suggestions including real time - and immediately started having random crashes in WOFF.
I immediately stopped using real time and am using the affinity shortcut.
So far so good.
I would not consider my system as one with having "limited processing capabilities"
At this time I have not formed an opinion as to if setting affinity helps at all.
