and i dont know why, some people told me that its about the tv screen the told me you should get pc monitor so you can get better fps
even in battlefield 3 i get 40 fps in some areas but when i watch any gameplay of my amd r9 290x i can see that the fps is much much better its between 80-110 fps in gameplays
