I don't get it. Some areas my game runs fine on maximum settings at 60 FPS, like Grassy Island, Treasure Vault, etc, and then areas like FSC, IMF, Arenas, it barely runs at 15-20FPS even when I turn things down.
What gives? Why does this game run so great in some areas, and then take such an enormous performance hit in others that I can't even improve a little bit?
My PC specs are a dual-core processor at 2.9 GHZ, Radeon HD 5570 video card (1gb version), and 5gb of RAM. There's nothing else running that would be eating resources.
