Settings Adjustment: Turn every graphical setting to its Lowest possible value or Off.

Resolution: Drop your resolution to a lower setting than your native monitor resolution (e.g., if you play at 1080p, drop to 720p or 800x600).

BO2 Error: Failed to allocate from state pool :: Call of Duty

This report is intended for PC gamers, technical support staff, and community forum moderators. It assumes the user has already applied the official game patches and is still encountering (or wants to understand) the error. Tier 2: The Graphics Driver & Overlay War

Tier 2: The Graphics Driver & Overlay War

Modern overlays are the #1 cause of the "state pool" error.

Fix C: Disable ALL Overlays

Fix D: Force the Game to Use Your Dedicated GPU (Laptops ONLY)

4. If You Still Get the Error (Post-Patch)

Try these manual fixes (which work for the remaining cases):

  1. Reset config – Delete players\config.cfg in the game folder, then verify game files via Steam.
  2. Set launch options – In Steam → Properties → Launch Options, add:
    +set r_state_pool_size_mb 384
  3. Disable Steam Overlay – Known to conflict with memory pools in some older games.
  4. Run in Windowed mode – Add -windowed to launch options.
  5. Limit VRAM usage – Use NVIDIA Control Panel or AMD Adrenalin to cap the game’s VRAM access.

Tier 3: The Nuclear Option – DGVoodoo2 (The Unofficial "Patch")

If Tier 1 and 2 fail, you need the community’s real patch: DGVoodoo2. This is an open-source translation layer that converts the game’s old DirectX 9 calls into DirectX 11 or 12. It completely bypasses the state pool issue.

How to Install DGVoodoo2 for BO2:

  1. Download the latest DGVoodoo2 from the official site (do not use random mirrors).
  2. Extract the archive. Go into the MS (Microsoft) folder, then x64 folder (even if your OS is 32-bit, use x64 for modern Windows).
  3. Copy these three files: D3D9.dll, D3DImm.dll, and DDraw.dll.
  4. Paste them directly into your BO2 game folder (where t6mp.exe lives).
  5. Run DGVoodooCpl.exe (the configurator) from the DGVoodoo folder.
  6. In the configurator, under the DirectX tab, set "Videocard" to your actual GPU (not "Unspecified").
  7. Under General, uncheck "dgVoodoo Watermark".
  8. Click Apply, then launch the game.

Why this works: The game now thinks it’s talking to an ancient DirectX 9 card, but DGVoodoo silently translates everything to modern DX11/12. The "state pool" error disappears permanently.

Understanding the “Failed to Allocate from State Pool” Error in BO2

The “Failed to allocate from state pool” error is a memory allocation crash that has affected PC players of Call of Duty: Black Ops 2 for years. It typically occurs when the game engine attempts to reserve memory for graphical assets (textures, shaders, models) but cannot find a sufficiently large contiguous block of memory in the state pool—a reserved portion of RAM or VRAM used for rendering states.

Common triggers include:

1. Verify Game Integrity

Steam updates can sometimes corrupt the file allocation table.

  1. Right-click the game in Steam -> Properties -> Installed Files.
  2. Click Verify Integrity of Game Files.
  3. Wait for the process to finish and relaunch.

Method: Increase State Pool via Registry (Windows)

This forces the game to use a larger, custom state pool.

  1. Close Black Ops 2 completely.
  2. Press Win + R, type regedit, press Enter.
  3. Navigate to: 
    HKEY_CURRENT_USER\Software\Treyarch\Black Ops II
  4. In the right pane, right-click → New → DWORD (32-bit) Value.
    • Name: StatePoolSize
    • Value (Decimal): 1536 (for 1.5GB pool) or 2048 (for 2GB pool)
  5. Optional (if using high-res textures):
    Create another DWORD: MaxTextureMemory
    Value (Decimal): 2048
  6. Click OK, close Registry Editor.

Why this works: The game checks the registry for StatePoolSize before falling back to its default (512MB). A value of 1536-2048 MB resolves allocation failures on GPUs with 4GB+ VRAM.
