The "Failed to allocate from state pool" error in Call of Duty: Black Ops II is a notorious memory-related bug that typically occurs during specific campaign missions (most notably "Cordis Die" in LA) or when purchasing perks in Zombies. It stems from the game engine's inability to manage resource allocation correctly, often triggered by modern high-resolution settings or specific in-game events. 1. Reduce Graphics and Resolution
