This game is very unstable with overclock, yeah, you saw it right, the game is unstable, why? My older video card MSI GTX 460 had a factory clock of 760, if you tried to overclock it to even 770 or higher the game would go black screen. This game can't demand much besides stress stability tests(furmark, kombustor, etc). Also it was the only game causing trouble for me. Now I have the amd r9 280, and guess what, the same thing if you overclock it a bit, however the BF4, Crysis 3 and other demanding games have no problem with it, how is this possible, even uniheaven engine runs perfect. I'm not new with overclocking, I know how to monitor temp and other things, however thinking that game that have medium graphics crashes, it is a problem(even with two different brands of gpu's).
