The Black Ops 2 engine (an evolution of the IW engine) was designed in 2012. It allocates fixed memory pools for system resources based on the hardware standards of that era. Modern systems with massive VRAM, high core counts, and aggressive overlay software can easily overflow these rigid, hardcoded memory limits, causing an immediate crash.
