I just downloaded this game. I am very eager to play it, but it seems to be lagging immensely. It's not so much that the game is going slow, but more like my frames per second are really low. I've tried every setting on the options menu, but I was wondering if others encountered this. It's like my frame of references (the world) keeps jumping back and forth into and out of the screen. It's really irritating. Anyone know a fix?
