Part 1: Blue Protocol: Star Resonance Overview

Blue Protocol: Star Resonance is a free-to-play, cross-platform MMORPG developed by Shanghai Bokura Network Technology and published by A PLUS JAPAN. Set in the fantasy open world of Magna, players embark on adventures as "Resonators," wielding unique star-powered abilities. Including highlights below:

The game initially launched its China-exclusive test on July 17, 2025, and officially rolled out globally on October 9, 2025, across PC (Steam, Epic Games) and mobile platforms (iOS, Android).

Part 2: Why Lag Occurs in Blue Protocol: Star Resonance

Lag in Blue Protocol: Star Resonance typically stems from:

1. Server Connection Route Congestion

Given that over 9.8 million players have pre-registered for Blue Protocol: Star Resonance, the massive player base will cause congestion in server connection routes during the initial server launch period. This results in lag and slow loading times when players attempt to access the game.

2. Geographical Server Distance

• Chinese servers are physically distant from players in North America, Europe, or Southeast Asia, causing high ping (>150ms).
• Network congestion during peak hours exacerbates delays.

3. Device Performance Limits

• Blue Protocol: Star Resonance has a file package size of 23GB on PC, while the mobile version requires approximately 6.9GB (Android) and 7GB (iOS) of storage space. Insufficient storage space on players' devices can restrict game loading speeds and lead to lag issues.
• Outdated hardware or low VRAM can lead to stuttering in graphically rich areas.

4. Network Configuration Issues

• ISP throttling or unstable Wi-Fi connections disrupt data packets.
• Background apps (e.g., cloud sync, updates) consume bandwidth.
