i've found a solution to this, but it has to be done everytime i play the game (so the word temporary is an understatement). it is a graphics bug.
this is what i did:
upon getting into the game, i go to options, then graphics, i check the disable HD&T box and click ok.
i know have text on the buttons, however once i quit the game i have to go through this whole process again as the game doesn't remember graphics settings (like refresh rates). hope this helps.
