What is iNumHWThreads?

[Mr. Ox]

I'm using the Fallout 4 tweaker and I see this performance tweak that is set to 0. I have 4 cores, will my performance possibly increase if I set this number to a 1 or 2?

It's used to set how many cpu cores the game uses. If I remember correctly, 4 is the maximum FO4 can use.

Check your cpu specs, then go ahead and tweak away.
