Presets

Latency & Tick

Your RTT 60 ms

Network round-trip. The number shown in-game. Does not include bufferbloat or server processing.

Your PlayerRTT 76 ms

RTT + server processing time. Shown as "PlayerRTT" in EFT/Arena fps overlay. Must be ≥ RTT.

Opponent RTT 60 ms

Opponent PlayerRTT 76 ms

Not visible in-game. Defaults to opponent RTT + 1 tick. Adjust to model a server-stressed opponent.

Server tick rate 60 Hz

Interpolation buffer 120 ms

Bufferbloat OFF

Simulate connection under load (someone downloading / streaming on your network)

Client & Events

Max jitter variance (±ms per leg) 0 ms

Simulates random network variance per leg. Values are locked when jitter = 0; use the re-roll button when jitter > 0.

Reaction time offset 0 ms

Delay before opponent shoots (you shoot at t=0 or t=peek).

Drop your first input packet (missed tick) Drop first server→opponent packet (missed tick) Include projectile dynamics

Corner swing (line‑of‑sight)

Enable corner‑peek mode

Adds physical movement delay before you can see opponent. Affects when your shot is possible and when opponent becomes visible to you.

Your peek time to clear LOS 150 ms

Time before YOU can see and shoot the opponent.

Opponent's occlusion delay 0 ms

Time before opponent can see YOU (e.g., they're also peeking).

Projectile

Your shot (Chart A)

Bullet velocity 900 m/s

Distance 50 m

Opponent shot (Chart B)

Bullet velocity 900 m/s

Distance 50 m

Flight time A: — | Flight time B: —

Trade outcome (server)

—

Based on server registration time — this is what the game uses to decide who wins.

Server registers your shot

Server registers opponent shot

Perception gap

—

How much earlier/later you see their hit vs they see yours.

Opponent sees your impact

—

You see opponent impact

Total delay opp→you

Each chart uses RTT/2 ± jitter per leg. Server processes on next tick boundary after arrival. Interpolation buffers past data. Projectile impact tick-snapped to next server tick after flight.

Visual perception — when each player actually sees the other

not yet visible becomes visible Δ —

Bars show the time from moment of action until the remote player becomes visible on screen.
