Will 16GB of RAM help reduce stuttering in games?

Yes. 16GB gives enough headroom so modern games can breathe without the OS swapping to storage, which causes micro-stutters. 8GB is the bare minimum that gets eaten up by the game, Windows, and background apps. For recent titles like Cyberpunk or Elden Ring, upgrading from 8GB to 16GB is the cheapest performance gain you’ll feel.
