Dread Viper

ok so in control pannel it reconizes the controller and it passes all the tests however when I go into the game and go under gameplay options it doesn't bring up a game controller or joystick option to play can anyone tell me what I have to do here to play it with a controller? I honestly cannot stand the pc controls for it I've been a console gamer too long and only got the PC version because of the updates to be less buggy
