Help! OpenGl on windows with bootcamp

Hi, so I've installed windows 8 on my iMac sucessfully, but for some reason (after updating the drivers through intel AND bootcamp) my opengl is still only 1.1 and i cant figure out how to update it. Most of the games i am trying to play require atleast opengl 3.0. Also my sound wont work when i use windows (using headphones and external speakers, neither work). Any information will help, thank you!
