01 1. [Key Comparison] Gaming from South Korea to Overseas Game Servers
While South Korea boasts the world's fastest domestic fiber optic speeds (up to 10 Gbps), international underwater fiber optic cable routing can introduce severe bottlenecks, high jitter, and packet loss when connecting to game servers in California, Tokyo, Singapore, or Frankfurt.
Target Game Server Region | Standard ISP Direct Latency | Optimized GPN / Multi-Route Latency | Primary Routing Bottleneck | Recommended Solution 🇺🇸 US West (Los Angeles / Oregon) | 160ms - 220ms (High Jitter) | 105ms - 125ms (Stable) | Transpacific undersea cable throttling | Dedicated multi-route booster (GearUP) 🇯🇵 Japan (Tokyo / Osaka) | 35ms - 55ms | 18ms - 26ms | Transit peering hops via Hong Kong | Subsea direct line routing 🇸🇬 Southeast Asia (Singapore / HK) | 80ms - 110ms | 45ms - 60ms | ISP routing loops | Fiber route optimization 🇪🇺 Europe (Frankfurt / London) | 260ms - 320ms | 190ms - 215ms | Multi-continental transit | Optimized tunneling
02 2. Why Standard VPNs Fail for Gaming (And Why GPN Multi-Routing Works)

Frequently Asked Questions (FAQ)
QWill using a game booster get me banned on Valorant or Steam?
No. GearUP Booster is officially whitelisted and compatible with Riot Vanguard, Valve Anti-Cheat, and Easy Anti-Cheat because it only optimizes network routing paths without modifying game files.
QCan I play on North American servers from Seoul with sub-120ms ping?
Yes. Utilizing direct transpacific optimized GPN routing reduces the Seoul-to-US West (Los Angeles) ping from the standard 180ms+ down to an ultra-playable 110ms-120ms with 0% packet drop.
