FIFA 15's minimum system requirements include a 2.0 GHz processor, 4GB of RAM, and a DirectX 11 compatible graphics card. While 4GB of RAM meets the minimum requirements, players soon discovered that the game was not optimized for such low-end hardware. The game's engine, Frostbite 2, is a powerful and demanding game engine that requires significant system resources to run smoothly. As a result, players with 4GB of RAM experienced severe lag, stuttering, and frame rate drops, leading to an unsatisfactory gaming experience.
