so i played as the vasari, made about 10 ships that lays down mines,. had to drive my lil sis to school so i was gone for about 20 minutes,. when i came back the game is soooooo slow. about 5 FPS!! and theres more than 3000 mines layed out. my game never slows down that much even if i have the same ammount of frigates out there (if i zoom in to those ships i get around 20 FPS.). however havign 3k said mines on the field, my game crawls, i turned down every settings and effects to the lowest. still the same. any ideas why?
