--#region Adjust process affinity and prioritity

-- The rendering thread appears to pin itself to the first computing unit of
-- a computer. The first computing unit is often also used by othersoftware,
-- including the OS. Through empirical research the framerate of the game is a
-- lot more consistent when we do not give it access to the first computing
-- unit.

-- That is what this section helps us do. The game functions best when it has
-- at least four computing units available. If we detect someone has 6 or more
-- computing units then we take the game off the first compute unit.

-- Note that we can not make the distinction between real computing units and
-- computing units that originate from technology such as hyperthreading.
