Hello there, this happens after +/- 20 minutes of play. Tried clean instal of Windows, GPU drivers, steam and game files itself. Tried RAM stick switch, GPU contact on MB etc. Overheating is out of question as GPU and CPU temps wont exceed 70 degrees. Before the OS reinstall the problem occured as instant freezing of Arma without any error code and shutdown. Freezed the whole system and only restart or sign out was able to resolve the problem. Game is unplayable and im out of solutions. Please help. Thx!
