Hi, I few weeks ago I picked up Dead Rising 2 since it was a 3d vision ready game. Low and behold this game has an awesome 3d effect. Its just a zombie game but it sure is fun to play and the graphics are actually pretty cool. It need Games for Windows Live and you can get the update from there which makes the game smoother. I am running this game on a gtx 285 and with a full room of zombies it really does not slow down.
Look at my screenshots to get an idea of what kind of 3d it can make:
