Dual v Quad

[KDN]

You are right Athos,
I did a little experimentation and although the ProcessAffinityMask=XX line does have an effect, commenting it out (default) will let the IL2CoD use whatever it is available CPU wise (lastest beta patch).

Although, I have not seen the hyperthreading cores in action yet, all my 6 cores are showing around 30% activity on the free hunt mission (loaded to max) in any of the settings below:
;ProcessAffinityMask=63
ProcessAffinityMask=63
ProcessAffinityMask=255

There is still CPU processing room left unused, so I am assuming this why I don't see the hyperthreading cores waking up.
