What Lagcheck checks for Rematch
Packet-to-packet variation
Variations that can cause stutter and delayed hit registration.
Missing packets
Packets that fail to arrive. Measured in the iPhone app.
Under load
How the route reacts while the network is busy.
How lag shows up in Rematch
- A counterattack registers late or a player snaps back just as the next exchange begins.
- High jitter or packet loss can make actions feel inconsistent even when download speed looks fine.
Reference route
Your Wi-Fi or mobile connection and the path through your provider can affect this game. Lagcheck measures a regional reference route, not the private server for your match.
Practical tip: Test on an iPhone connected to the same home network before joining a match. Compare results near the router and while your network is busy.
Questions about lag in Rematch
Why can Rematch lag on a fast connection?
A counterattack registers late or a player snaps back just as the next exchange begins. Download speed alone does not describe latency, jitter or packet loss.
Does Lagcheck test the exact Rematch match server?
No. The browser uses HTTPS to a regional reference endpoint. The iPhone app can measure UDP packet loss on its test route; neither result identifies the private server assigned to your match.
