Call Of Duty Black Ops 2 Failed To Allocate From State | Pool Fix Better

Below are the better, more effective fixes — moving beyond the basic “verify game files” suggestion.

The Driver Rollback (For NVIDIA users)

Drivers after 2020 changed how memory is reported to 32-bit applications. While newer drivers are great for Cyberpunk, they break BO2. Below are the better, more effective fixes —

• Better fix: Download NVIDIA Driver 456.71 (October 2020) or AMD Driver 20.9.1. These are the last known drivers that treat BO2's memory requests "nicely."
• Install using Clean Installation (using DDU - Display Driver Uninstaller in Safe Mode).

4) Disable overlays and recording tools

Why: Overlays (Discord, Steam, NVIDIA/AMD overlays, Xbox Game Bar) inject DLLs and use VRAM, which can cause allocation failures.
How: The Driver Rollback (For NVIDIA users) Drivers after

• Discord: User Settings → Overlay → toggle off.
• Steam: Library → right‑click game → Properties → uncheck “Enable the Steam Overlay”.
• NVIDIA: GeForce Experience → Settings → In‑game Overlay off.
• Windows: Settings → Gaming → Xbox Game Bar → Off.

Also close background recording or streaming apps (OBS, ShadowPlay, ReShade, ENB). Better fix: Download NVIDIA Driver 456

4.2 Reduce system memory pressure

• Close browsers, Discord hardware acceleration, etc.
• Set Windows page file to system managed on an SSD.
