Before initiating the download, it is crucial to ensure your hardware is capable of running the game. Modern Warfare III is built on the IW 9.0 engine, demanding significant storage space and processing power. The minimum requirements typically call for a modern multi-core processor (such as an Intel Core i5-6600 or AMD Ryzen 5 1400), at least 8GB of RAM (though 16GB is recommended), and a graphics card equivalent to an NVIDIA GeForce GTX 960.
