Hello guys I have a good notebook: Intel core i5-2450m AMD Radeon 7670m 2 gb VRAM 6 gb DDR3 RAM I play dota 2 and Diablo III with 50-60 FPS on maximum settings, but ArmA 2: OA is lagging (15-20 FPS) on the lowest settings! It's awful! What should I do to fix it? Help me please, I bought this game only for DayZ and I dont want to lose it..
