When I start up arma 2 oa and reach the main menu the background scene will play and I will here sound but then it freezes and I have to stop it in task manager so it doesnt make my computer crash and it says my amd display driver has stopped working and recovered. I am not having this problem with regular arma 2 just oa. If someone could help that would be great. I have the amd radeon HD 7730M graphics card. I used to be able to play this just fine but up until recently this problem started happening.
