  • Network: Connection speed and latency
  • Storage: Cache and temporary files

Performance Metrics to Monitor

  • Frame rate (FPS): Smoothness of animation
  • Input lag: Delay between action and response
  • Loading times: How quickly games start
  • Memory usage: RAM consumption
  • CPU temperature: System heat levels
