You can force it to respect your hardware, cap your framerate for stability, lower internal rendering resolutions for a playable FPS, and finally enjoy James Heller's brutal, chaotic rampage through a mutant-infested New York without technical interruptions. These methods are the collective work of countless dedicated fans who refused to let a great game be defined by its terrible port. Now, it's your turn to play.
