i upgraded my pc a few days and ago and it runs every game i own flawlessly on ultra including BF4, but for some reason when i go to play DayZ my FPS will not go above 15 within a city and sits at about 20 in the wilderness. my specs: GPU: Sapphire radeon r9 280x dual-x oc overclock CPU: i5 2400 3.1 GHz RAM: 8GB @1600 MHz OS: Windows 7 Before i upgraded i was running on a low end GPU with a half the RAM and performed massively better than i do now it just makes no sense to me at all. Previous specs: GPU: Nvidia geforce GTS 450 CPU: i5 2400 3.1 GHz RAM: 4GB @1600MHz OS: Windows 7
