Players have reported that Call of Duty: Modern Warfare 4 (MW4) can launch itself automatically on certain PCs without user input. This background activity, linked to shader caching, has caused MW4 to consume up to 80% of CPU and 50% of RAM, even when users are engaged in unrelated tasks like watching YouTube. The unexpected resource drain has led to performance slowdowns and concerns about the game running processes without consent. Players should monitor their systems for this behavior to avoid disruptions during other activities.

  • MW4 uses high CPU and RAM while running in background.
  • Issue tied to shader caching process causing auto-launch.
