Getting really bad fps such as 10 per second When I open chat or Esc menu then fps goes up to 30 or more. Would like to ask if anyone knows how to make this permanent without opening my chat or menu, can't really play with those open. Setup: Windows 7 Home Premium 64-bit i7-2670QM CPU @ 2.20GHz (8 CPUs) Boosts to 3.1GHz when necessary 6144MB RAM GT555M 3GB VRam I know it's a laptop but it used to run ARMA 2 DayZ mod much better than now.
