Movement speed slow?

[Lamil]

Recently boot camped my Macbook Pro and installed windows 7pro. My problem is, besides running on a mac, that my movement speed is super slow. Like its almost like my character isn't running. People in game say it looks like my toon is encumbered or something but none of them are. Any ideas why its like my characters run in slow motion? I can't even outrun mobs with sow on

Any help would be great
