Well, I just tried it for the first time, & it seems to have fixed my issue!!!
I had a session the other day that was CPU spiking @ 64. Today, I opened the session again - still spikey. Next, I set processor affinity to NOT use cores 1 & 2 (of 12). Then, I set priority to high. The spikes stopped & the session ran perfectly. Reset affinity/priority back as before, & the spikes returned. Tried it again: 1 & 2 off/high priority ---> spikes stopped. I'm sold!!! Here's how to do it:
