DEV ERROR 6065 in Call of Duty (MW, Warzone, MW2, MW3) means the game failed to create a DirectX device. This typically happens during launch or when loading into a match.
How to fix it:
- Clean install your GPU driver — boot into Safe Mode, run DDU, install latest driver
- If the game has a config file or launcher option, switch from DirectX 12 to DirectX 11
- Disconnect extra monitors — multi-monitor setups can confuse DX device creation. Test with one monitor
- Update Windows fully — DX12 improvements come through Windows updates
- Delete the game's 'players' folder in Documents (contains settings cache) — the game will recreate it
- Run the game as Administrator
- Make sure your GPU meets minimum specs — DX12 requires a GPU with Feature Level 11_0 or higher
- If on a laptop, ensure the game is using the dedicated GPU, not Intel integrated graphics
