I just purchased this game and all of its DLC content via steam.  its patched to 1.2 and starts fine.  Yet when i start a new game, on the character screen, i can not see the character models, and if i start a game, i  get a white screen which i can zoom out to cloth map mode, yet when i zoom in i get the milky white screen.  my laptop specs are:

Intel(R) Core(TM) i7-2675QM CPU @ 2.20GHz,

 AMD Radeon HD 6750M

and 8gigs of ram. and windows 7

  I do have  a duo video card Intel(R) HD Graphics Family, but in games it uses the amd 6750m.

 Any assistance would be appreciated.

I have disabled the powerplay option in my catalyst control center as the 2nd main sticky suggested, to no avail
