Copyright 1999-2025 Playnet, Inc.[/p][p][/p][h3]WHAT IS PREDICTION & SMOOTHING?[/h3][p]In an online game like WWII Online, every player’s actions (movement, shooting, turning, etc.) are constantly sent over the internet to the game server, and then shared with other players. But because the internet has delays (called latency), your computer can’t always know exactly where another soldier, tank, or plane is at the exact moment.[/p][p]To solve this, the game uses Prediction & Smoothing:[/p]
  • [p]Prediction – Your client predicts where another player should be right now, based on their last known speed, direction, and actions.[/p]
  • [p]Smoothing – When updated data arrives from the server, the game gently corrects any differences, so the motion looks natural instead of jerky or teleporting.[/p]
[p]Why is it Important?[/p]
  • [p]Fluid Motion: Without prediction and smoothing, enemies and teammates would constantly appear to “jump” around the battlefield as new updates arrive. That would make tracking targets or coordinating with allies nearly impossible.[/p]
  • [p]Fair Shooting: By smoothing out player positions, your aim feels accurate and fair even when there’s internet delay. Without it, you might shoot at where someone was instead of where they are.[/p]
  • [p]Immersion: WWII Online is all about scale and realism. Smooth, continuous movement keeps the battlefield feeling alive and believable, instead of looking broken or robotic.[/p]
  • [p]Playability with Latency: Not everyone has the same internet speed. Prediction and smoothing allow players across the globe to fight together without constant stutters ruining the experience.[/p]
[p]In short: Prediction & Smoothing is the hidden tech that makes the massive battles of WWII Online feel smooth, fair, and immersive—bridging the gap between internet delays and real-time combat.[/p]
