Honkai: Star Rail FAQ — Ping, Servers, Network

Yes. PingAim auto-detects StarRail.exe and routes its traffic through your optimal network interface using a WFP kernel driver. It is compatible with unifairy.sys — PingAim operates at the Windows network layer and does not interact with the game process in any way, avoiding the DLL injection that unifairy.sys blocks.

Less than in most online games. Honkai: Star Rail is entirely turn-based — ping does not affect combat performance, timing, or outcomes. Ping mainly affects open-world exploration smoothness and can cause disconnections if very high (300ms+). If you are on the correct regional server with a stable connection, ping is rarely a problem.

No. Server selection is permanent at account creation. If you chose the wrong server and have high ping, your options are: (1) start a new account on the correct server, losing progress, or (2) use a network optimizer like PingAim, which routes StarRail.exe through whichever of your network interfaces has the most direct path to your current regional server (results depend on your ISP, second connection, and physical distance — no fixed ms improvement is promised).

Using stable network routing tools for latency improvement carries low risk. HoYoverse's official policy is that VPN use is at the player's own risk, and may trigger account review for unusual access patterns. PingAim uses a WFP kernel driver that does not inject code into the game process — this is the safest approach for HoYoverse titles and avoids the injection detection that unifairy.sys enforces.

Frequent disconnections are usually caused by: (1) unstable WiFi — switch to wired Ethernet; (2) poor ISP routing to HoYoverse's Alibaba Cloud servers; (3) playing on the wrong regional server with 300-500ms ping; (4) ISP packet loss during peak hours. Running a traceroute to the game server can identify where the instability occurs.

Choose the server closest to your location: America for North/South America, Europe for Europe/Middle East/Africa, Asia for Japan/Korea/Southeast Asia/Australia, TW/HK/MO for Taiwan/Hong Kong/Macau. This decision is permanent — you cannot transfer your account between servers later.
