Known Lag Problems
These problems are reported by real players. If your region or ISP is listed, a network optimizer is likely to help.
Australia / Oceania
20–60ms (local) or 150–300ms (US fallback)- Limited server population means frequent fallback to US West or Southeast Asia servers
- US West fallback adds 150–200ms; SEA fallback adds 80–150ms
- Off-peak hours (daytime on weekdays) often result in cross-region matchmaking
South America
120–260ms- No dedicated South America Azure region for Sea of Thieves
- Players connect to US East servers, adding 100–200ms baseline ping
- Early testing showed SA players at 260ms before Azure expansion
Middle East / Africa
150–280ms- No local Azure Sea of Thieves region — all connections route to Europe West or North
- South African players experience 150–250ms to European servers
What players commonly report
- Ghost hits and hit registration failures in sword and gun combat
- Rubber-banding during heavy combat (boarding, multi-ship fights)
- High ping when matched into cross-region sessions when joining friends
- Australia players falling back to US servers during off-peak hours
- Server instance performance degradation with many active players/events
How to Fix It
Try these first — they're free and solve the problem for most people.
01 Check and fix your NAT type
1. Open your router admin panel (usually 192.168.1.1 or 192.168.0.1) 2. Forward these UDP ports to your PC: 88, 500, 3074, 3544, 4500 3. Also forward TCP 3074 4. Alternatively, enable UPnP in your router settings 5. Restart Sea of Thieves and verify: Settings → Network → your NAT type should show 'Open'
Strict or Moderate NAT causes failed crew joins, session instability, and can increase ping as traffic gets rerouted through Microsoft's relay servers instead of a direct path.
02 Switch from WiFi to wired Ethernet
1. Run an Ethernet cable from your router to your PC 2. In Windows: Settings → Network → set the Ethernet adapter as the active connection 3. Disable WiFi on the PC while gaming to avoid adapter switching 4. Relaunch Sea of Thieves and check your ping overlay
WiFi introduces 5–30ms of jitter even on strong signal, which maps directly to rubber-banding in Sea of Thieves. A wired connection with slightly higher average ping will feel smoother than WiFi with lower average but high jitter.
General network tips (not Sea of Thieves-specific)
03 Enable the in-game ping display (PC only)
1. Launch Sea of Thieves 2. Go to Settings (gear icon in the main menu) 3. Select the Interface tab 4. Enable Performance Counters 5. Once in-game, your ping (ms) and FPS are shown in a small overlay 6. Watch for sudden spikes during combat or boarding — those are network events, not FPS drops
Confirms whether your problem is network (ping spike) or GPU/CPU (FPS drop). These require completely different fixes. Don't guess — check the overlay first.
04 Close background apps using bandwidth
1. Press Ctrl+Shift+Esc to open Task Manager 2. Click the Network column to sort by usage 3. Close any apps downloading updates: Windows Update, Steam downloads, browser video 4. On your router, disable active torrents or large downloads on other devices 5. Sea of Thieves uses roughly 1–5 Mbps; leave at least 10 Mbps headroom
Buffer bloat — when your router's upload queue fills up — causes latency spikes of 50–200ms that appear as intermittent rubber-banding. The fix is free and instant.
Regions with good connectivity
Players in these regions likely won't benefit much from a network optimizer.
- Western Europe — EU West Azure region typically delivers 10–50ms for players in UK, France, Germany, Netherlands, Nordics
- Eastern United States — US East Azure delivers 10–50ms for the US East Coast player base, which is the largest NA player pool
Still lagging? The problem is likely your ISP's routing to the game servers.
PingAim detects Sea of Thieves automatically
No manual config. PingAim identifies Sea of Thieves by process name and routes it through your fastest connection using a kernel-level WFP driver.
