It will be determined by how graphics intensive your game is. For example, if a game consisted of 4 segments, and no lights, then it will be less system requirements intensive then those same for segments and 40 lights. That's why when you add a lot of lights/dynamic entities it lowers the FPS. Because it takes more system usage to create those scenes.
Hope that clears it up for you. Just try and optimize your maps for as many people as possible, and you won't have to worry about system requirements too much.
