A 5v5 hero shooter where abilities, positioning and team objectives change quickly.
How long packets take to reach and return from the reference region.
Variations that can cause stutter and delayed hit registration.
Packets that fail to arrive. Measured in the iPhone app.
How the route reacts while the network is busy.
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.
An ability fires late, a player appears to die behind cover or an opponent snaps into a new position. Download speed alone does not describe latency, jitter or packet loss.
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.
