I am using the nVidia GeForce 260 GTX with the latest drivers (258.96). I have been playing the game almost every night, but I am getting a freeze condition that is not recoverable. I ctrl+alt+del and it takes minutes before the window pops up. I shut down the game process and then get a windows error message saying that the Display Driver stopped working. I am still searching for a solution, but so far no luck. Any advice would be greatly appreciated.
