[citation][nom]InvalidError[/nom]Even when PS4 ports come to PC, desktop quads run at ~2.1X the PS4's CPU clock rate and should easily make up for the lack of octo cores. Ports will likely get optimized for that by folding some threaded bits back into their main threads to avoid unnecessary threading overhead for trivial code.[/citation]
But that's too much work. If many ported games still only went up to DX9, what makes you think they'll put in extra effort to "fold" back in the threads?
Also, folding threads into one giant one? You should play Cities XL sometime. It's a single-threaded game first released in 2010 and so far received a 2011, 2012, and 2013 DLC, but that doesn't mean it won't try to process a metropolis's hundreds of thousands of commuters.
God that game is horrific even on an i5... A friend of mine had to disable three of his i5 2500k's cores and clocked the heck out of the one core to delay the inevitable bog-down of the traffic simulator.
