RuneScape can be run with high or low-detail graphics; high-detail mode enhances texture and design, whereas low-detail provides a cleaner look and can reduce lag on older or less powerful computers. In February 2005, Jagex began the process of updating the graphical images in the RuneScape cities and the wilderness, planning ultimately to improve the graphics of the entire free area of RuneScape without causing more lag for people using dial-up Internet connections. RuneScape places emphasis on granting players the ability to customise their characters by supplying a wide choice in character models. Unlike many games in the genre, player characters are always human; however, players can choose their appearance from hairstyles, body types, facial features, clothing options, and sex. On-screen appearance is further optimised by wearing or wielding items, with each different item having a unique image. Standard weapons of the same class, such as swords, use the same set of animations in combat; however, some special weapons have their own, distinctive animations that differ completely from those of other weapons in their category. Players' appearances can be changed using special equipment or during particular game events. Transformations into frogs, mushrooms, eggs, and other objects and animals can occur, depending on the circumstances. These "morphs" are temporary, and sometimes allow players to avoid negative gameplay effects or access otherwise unreachable areas; however, they restrict certain activities that human characters are normally allowed to perform. Every activity performed by a player, such as planting a seed in a farming plot or walking down a street, has its own distinctive animation. Players can also express emotions through the use of emotes, which are specialized animations that can be performed at will. New players start out with most available emotes; some, however, must be earned by completing quests, random events, or holiday events.
