Disclaimer:

Batman: Arkham Asylum is a notoriously unstable game on modern PC hardware. The "General Protection Fault" (GPF) is usually caused by the game's physics engine conflicting with modern CPUs (specifically those with high core counts) or the SecuROM copy protection failing.

• Note when the GPF occurs (startup, specific mission, cutscene).
• If an error dialog lists a module or DLL, record its name — that points to the failing component.
