Hyper-threading on or off for DCS?

I feel that without HT my DCS seems smoother with less FPS fluctuations....although FPS remain the same as before I turned the HT off

I found this weirdness, if I leave the affinity mask for a default, I have the most busy fake core?

If you manually assign only those physical everything seems fine.
