i had the game first downloaded on my game hdd, i was able to play the installation for one hour without problems. after the second start which failed, i redownloaded the game from steam. this time i installed it on my ssd (should no defrag need), which now shows up the same problems as when it was installed on the hdd. i have also the arma series installed which start without any problems, also my pc is at least 6months old.
i agree with the hardware problem but i have no clue what it could be since all other games and applications running really well.
PC specs: intel i7-2700k@3.50Ghz, 16gb ram, nvidia gtx660, win8
