Oh, don´t worry, madpaddy.
Just ignore weary ol´ Al.
He´s only been traumatized the recent years by the way he sees all dev resources dedicated once to gameplay, story and all washed away now in favour of all out graphics and eye candy - a fear harassing him at every corner.
While there´s certainly a valid point in it, he´s strictly exaggerating and lashing out pointlessly whenever he can.
Me, sharing a certain soft spot for the tech aspect of games, i can relate to you and of course you asked a legitimate question that shouldn´t be faced with unmotivated resentment.
As for your question, Al was right w/ at least s.th.:
- Div2 not only has multi-threading in it already but even makes it an inevitable requirement in terms of demanding multi-core CPUs (which might not be exactly the same, but close).
If you look for the sysspecs given about the game, you´ll find Dual Core listed at minimum.
But it is really an interesting question to know how the game really scales over the various classes of multi-core available these days (dual -> triple -> quad core).
I frankly do not know and i haven´t seen a word from the Larians on that particular topic unfortunately - yet!
