BTW  like someone said and is so true, is the fact of CPU power used by this game ( same as ancestors if we think a little a bit, the latest ones at least), but i can say with no doubts, already tested and still using it, the game runs with a I5 4th generation a 4440 @ 3.10 Ghrtz stock (no o'clocks), 8 GB Ram and a old sata 500 Gb all placed on a Asus MB B85 PLUS, the game runs good, i notice only that if a use twitch, or something that uses CPU on background while playing, some little breaks on fast moves with camera.

Made an experience,  a litle bit "cientific" and the result was that the game runs with GTX 650 TI 2GB with MID res LOL and stable, cool ah, for those who talks about bad optimzations in the game. 100 hours played stable @ 45 fps and guess what some details on high, the game beautiful and realistic, not far from 1060 set up, already tested 200 h, start new game after finish story erlier without the nightmare mode
