I have tried differnt settings as far as graphics. I have even reformatted my computer and still does it after the reformat. It sucks cause I will be in a good game and poof the game crashes. I will have to crt alt del and end arma 3. Says Arma 3 is not responding. I am not sure if this has to do with my g card. I have a nvidia Gtx 580.
