Part 4: The Asylum's CPU Straightjacket (Multi-Core Fix)

The General Protection Fault often fires when the game tries to sync a physics calculation across 16 CPU threads. You must restrict the game to 4 cores.

What Causes the General Protection Fault?

Before diving into the fixes, it helps to understand the villain behind the glitch. Arkham Asylum runs on an older iteration of Unreal Engine 3. When the game was released, 4-core CPUs were the standard. Today, many gamers run 6, 8, or even 16-core processors.

The game’s physics engine (PhysX) and engine threading often struggle to handle modern CPU architectures, resulting in a memory violation known as a General Protection Fault. Essentially, the game tries to calculate physics or threads on a core that it doesn't know how to address, and the system shuts it down to prevent damage.

With that in mind, here are the solutions, ranked from easiest to most advanced.
