The COD MW2 system requirements kicks things off asking for either an Intel i3-6100, AMD Ryzen 3😊 1200, or even the ten-year-old Core i5 2500K CPU paired with 8GB of RAM.

Modern Warfare is typically the😊 free version which has a huge map. I wouldn't worry about it personally. That game is a resource hog and😊 RAM usage probably goes up and down quite often. I still use 16g and have no problems running it.
