Is 8GB of RAM enough for modern shooters like Call of Duty Warzone or Battlefield 2042?

No, 8GB is not enough. While upgrading to 16GB only gives 10–20% higher average FPS, the real win is eliminating stutter—those sudden frame drops in firefights disappear because the system isn’t constantly swapping textures. Minimum requirements lie by assuming a clean Windows install, but real-world use with Discord, Chrome, and background apps chokes performance before the game even loads. You’re leaving performance on the table with 8GB.
