To understand the fix, one must first understand the failure. The Black Ops 2 engine, a heavily modified version of the Quake III: Team Arena engine (id Tech 3), was designed in an era when 512MB to 1GB of video RAM (VRAM) was considered lavish. The "state pool" is essentially a reserved block of memory that the game uses to manage dynamic states—textures, shaders, and buffer data. On a modern system with 6GB, 8GB, or even 24GB of VRAM, the game’s 32-bit executable often misreads the available memory. When the engine asks the system for a chunk of the "state pool" and the system returns a value larger than the game’s 32-bit address space (limited to roughly 3.5GB total memory), the game panics. Alternatively, driver overhead and background applications can fragment the memory pool, leading to the same error. In essence, the game chokes on abundance. Now the game will launch in borderless windowed mode
