Gamers are more latency-sensitive than any other use case—the gap between 80ms and 40ms decides first-move advantage in competitive games. In August 2026, XuanFeng completed a dedicated game acceleration optimization with line and protocol tuning.
Game traffic differs fundamentally from web and video: it is small, frequent, extremely latency- and jitter-sensitive, and mostly UDP. A generic tunnel adds jitter in UDP handling. Game acceleration needs dedicated UDP optimization and low-latency lines.
XuanFeng configures independent game lines for popular overseas games, prioritizing low latency and jitter with optimized UDP forwarding. Aggressive retransmission reduces lag from packet loss.
| Optimization | Measure | Effect |
|---|---|---|
| Game lines | Dedicated low-latency | Lower base latency |
| UDP optimization | Dedicated forwarding | Less jitter/loss |
| Protocol tuning | Aggressive retransmit | Fewer disconnects |
Before launch, the team tested latency on several popular games.
| Game | Before | After | Drop |
|---|---|---|---|
| MOBA (overseas) | 118ms | 42ms | 64% |
| FPS (overseas) | 132ms | 51ms | 61% |
| MMORPG (overseas) | 96ms | 38ms | 60% |
"Overseas latency dropped from 120+ to around 40—teamfights feel responsive and my teammates noticed my faster reactions." — A MOBA player
Game optimization continues as XuanFeng adjusts dedicated configs with each game update. If you're struggling with overseas latency, download and try it.

Overseas latency halved—competitive play feels much better.
Split tunneling is great—voice and browser stay unaffected while gaming.
Hope they support more niche overseas games later.
