This article will serve as your ultimate guide. We will dissect what the "Rendering Thread Exception" actually means, why Unreal Engine 3 throws this specific fit, and provide a step-by-step battle plan to make Gotham City stable again. Before we fix it, we must understand the enemy. Batman: Arkham City runs on a modified version of Unreal Engine 3 (UE3) . UE3 uses a multi-threaded rendering pipeline. In layman’s terms: your CPU tells your GPU what to draw (the Render Thread ), and your GPU draws it.

Remember: Even Batman needed a contingency plan. Your contingency is disabling tessellation. Go clean up the streets of Arkham City without the game throwing a tantrum.

Few things are more frustrating than settling in for a night of superhero crime-fighting, only to be ambushed by a villain you can’t punch: a critical system error. For fans of Batman: Arkham City , the "Rendering Thread Exception" (often accompanied by a crash to desktop or a blue screen) has been a persistent and infamous foe since the game’s initial Windows Live days.
