Check Your Connection to Core Keeper 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 Core Keeper
No native in-game ping display exists in Core Keeper. Use Windows Resource Monitor: Ctrl+Shift+Esc → Task Manager → Performance → Open Resource Monitor → Network tab. Find CoreKeeper.exe, note the remote IP, then in Command Prompt: ping <IP> -n 20 Not available in-game. External tool required (Resource Monitor + command prompt).

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