The game engine (IW 3.0) is not heavily multithreaded. It was designed in an era when dual-core CPUs were just becoming standard.
While the game can launch on minimal hardware, achieving a stable frame rate for competitive multiplayer often requires meeting or exceeding the recommended specifications.

The PC version defaults to a low Field of View (approx. 65), which can cause motion sickness on larger modern monitors. The game does not have an FOV slider in the standard menu. The game engine (IW 3
Yet, the true genius of the system requirements lay in the chasm between the minimum and the recommended specifications. To experience Modern Warfare as the developers intended—at a silky 60 frames per second, with high-resolution textures and full dynamic effects—players needed a considerable step up. The recommended spec called for an Intel Core 2 Duo E6400 or AMD Athlon 64 X2 4400+, 2 GB of RAM, and a graphics card like the NVIDIA GeForce 7800 or ATI Radeon X1800 with 256 MB of VRAM. This was a deliberate strategic choice. The Core 2 Duo line, launched just a year prior, represented the ascendancy of multi-core processing in gaming. By recommending a dual-core CPU, Infinity Ward was future-proofing the game while subtly pushing the market forward. The requirement also anticipated the rising memory demands of Windows Vista, an operating system notorious for its resource hunger. In this sense, the recommended specs were a promise: Modern Warfare was not just a game for today’s hardware, but a showcase for tomorrow’s. Yet, the true genius of the system requirements
