Known Lag Problems
These problems are reported by real players. If your region or ISP is listed, a network optimizer is likely to help.
South America
120-200ms to US East- No confirmed dedicated CIG/AWS server region in South America
- Brazilian players connect to US East (AWS us-east-1) — typically 120–200ms depending on ISP and routing
- Some Brazilian ISPs route São Paulo → Miami → Virginia, adding significant latency
- No community workaround — server assignment is automatic with no manual override
Southeast Asia
80-180ms depending on country and ISP- Asia-Pacific region (Singapore/Tokyo) exists but has low server population
- Players may be assigned to US or EU during off-peak SEA hours
- Philippine and Indonesian players report 100–180ms to Singapore nodes
- Server meshing cross-node latency compounds with base network latency
Middle East / Africa
70-200ms depending on country- No dedicated CIG region — players connect to EU (Frankfurt/Ireland) or US East
- Middle East to EU Frankfurt typically 70–120ms depending on ISP
- South Africa to EU typically 150–200ms
- No community workaround available
What players commonly report
- Interaction delay — pressing F to interact has noticeable server round-trip lag
- Desync during server meshing zone transitions (ships teleporting, quantum desync)
- High ping assigned to distant server regions with no manual override
- Landing zone lag spikes when many players are present
- Connection errors (10002, 15006, 19000) — often firewall or NAT related
- Client authority exploits — cheaters exploit the server trusting client position/ammo data
How to Fix It
Try these first — they're free and solve the problem for most people.
01 Switch to a wired Ethernet connection
1. Connect a Cat5e or Cat6 Ethernet cable from your PC to your router 2. In Windows: Settings → Network & Internet → Wi-Fi → turn off Wi-Fi 3. Your PC will automatically use the wired connection 4. Re-check r_displayInfo 3 — jitter should drop significantly 5. WiFi interference is especially damaging in Star Citizen where server meshing transitions already add latency
WiFi adds 5–30ms of unpredictable jitter. In Star Citizen, jitter compounds with server-side meshing latency, making the interaction delay feel worse than your raw ping number suggests. Wired connections are strongly recommended.
02 Close background bandwidth consumers
1. Press Ctrl+Shift+Esc → Task Manager → Performance → Open Resource Monitor 2. Click the Network tab — sort by 'Total (B/sec)' 3. Common culprits: Windows Update (Settings → Update → Pause 7 days), torrents, cloud backups, OneDrive sync, Discord video 4. Star Citizen downloads large asset bundles on first load of new areas — check if the game itself is streaming assets in the background
Star Citizen has higher bandwidth needs than most games due to world streaming and server meshing. Background bandwidth consumers compete directly with game traffic and cause ping spikes during loading transitions.
03 Verify your RSI launcher region setting
1. Open the RSI Launcher 2. Go to Settings (gear icon) → check if there is a region/datacenter preference listed 3. If you're in Europe and getting 150ms+ ping, confirm you're not being assigned to a US server 4. Use r_displayInfo 3 in-game to watch your actual ping during different play sessions 5. Note: Star Citizen does not have a manual server browser — assignment is automatic based on location
CIG assigns players to the nearest server mesh automatically. However, during high population periods or regional outages, players may be assigned to sub-optimal regions. Monitoring your ping helps identify if this is happening.
General network tips (not Star Citizen-specific)
04 Check your ping and network stats with r_displayInfo
1. Launch Star Citizen and load into the Persistent Universe 2. Press the tilde key (~) next to the 1 key to open the console 3. Type: r_displayInfo 3 and press Enter 4. A performance overlay appears showing FPS, ping (latency to server), packet loss, and memory usage 5. r_displayInfo 1 shows basic info, r_displayInfo 2 shows more, r_displayInfo 3 shows the most detail 6. To remove the overlay: r_displayInfo 0 7. Watch for ping spikes during combat or landing zone activity — if it jumps by 50ms+, that's a network problem
Confirms whether your problem is network latency (ping spikes) or server-side performance (low server FPS with stable ping). Essential first step before trying any fix.
05 Configure firewall to allow UDP 64090–64110 unrestricted
1. Press Win+R, type: wf.msc, press Enter (opens Windows Firewall with Advanced Security) 2. Click 'Outbound Rules' → 'New Rule' 3. Rule type: Port → UDP → Specific remote ports: 64090-64110 4. Action: Allow the connection 5. Profile: check all (Domain, Private, Public) 6. Name it 'Star Citizen Game Traffic' 7. Repeat for Inbound Rules 8. Also ensure TCP 8000–8020 is allowed for the RSI Launcher
Some firewalls or security software throttle unknown high-numbered UDP port ranges. Explicitly permitting Star Citizen's port range prevents packet inspection overhead that can add 20–80ms of latency.
06 Flush DNS and use a fast resolver
Press Win+R → type cmd → Run as Administrator: ipconfig /flushdns Then set DNS to Cloudflare: Control Panel → Network → Adapter → IPv4 → Preferred DNS: 1.1.1.1 / Alternate DNS: 1.0.0.1
Star Citizen's launcher and backend services use DNS for server discovery and authentication. Faster DNS reduces launcher connection time. In-game UDP traffic is IP-based after initial connection and is not affected by DNS.
Regions with good connectivity
Players in these regions likely won't benefit much from a network optimizer.
- Western Europe — AWS eu-central-1 (Frankfurt) provides excellent connectivity for most of Western and Central Europe. Major IXPs in Frankfurt, Amsterdam, and Paris ensure sub-50ms for most EU players.
- US East Coast — AWS us-east-1 (Virginia) is well-peered and the highest population NA region. East Coast US players typically achieve 15–40ms.
- Australia — AWS ap-southeast-2 (Sydney) serves AU/NZ players with a dedicated region, preventing the 200ms+ latency they would face connecting to Asia or US.
Still lagging? The problem is likely your ISP's routing to the game servers.
PingAim detects Star Citizen automatically
No manual config. PingAim identifies Star Citizen by process name and routes it through your fastest connection using a kernel-level WFP driver.
