Check Your Connection to Left 4 Dead 2 Servers

See how much latency your ISP routing adds

Detecting your location...

Estimates based on real-time measurement to nearest Cloudflare edge. Actual in-game ping may differ by ~15ms due to different routing to game servers. Your IP is sent to ip-api.com for city-level location — we don't store it.

How to check your actual ping in Left 4 Dead 2

Command / method Open console with ~ key, type: net_graph 1 — shows live ping, packet loss, and lerp in the bottom-right corner. Also visible on TAB scoreboard (rounded estimate).
Where to find it

Bottom-right corner overlay when net_graph 1 is active — shows 'ping: 45ms' and other network stats. TAB scoreboard shows a simplified ping column.

What you'll see

Small text overlay in the bottom-right shows FPS, ping in milliseconds, svcloss (server to client loss), choke, and lerp. The 'ping' value is your current round-trip latency to the game server.

If your actual ping is higher than our estimate, your ISP is routing Left 4 Dead 2 traffic through a longer path than necessary. That gap is exactly what PingAim optimizes.
