Understanding OneSync and Its Impact on Your Server
When launching a FiveM server, one of the most critical choices is deciding between OneSync Legacy and OneSync Infinity. This decision affects your server’s player capacity, performance, and synchronization efficiency. In this guide, we’ll break down the differences and help you determine which option suits your needs best.
What is OneSync?
OneSync is a custom synchronization system developed by CitizenFX (the team behind FiveM and RedM) to replace GTA Online’s traditional peer-to-peer networking. Unlike GTA Online, which distributes synchronization between players, OneSync centralizes sync control through a dedicated server, allowing for larger player counts and smoother gameplay.
With OneSync enabled, your FiveM server can host up to 48 players for free. If you pledge to Cfx.re via Patreon, you can unlock support for up to 1024 players, significantly expanding your server’s potential.
OneSync Legacy vs. OneSync Infinity: Key Differences
There are two main versions of OneSync: Legacy and Infinity. While both improve upon GTA Online’s networking, they differ in how they manage player synchronization and server load.
OneSync Legacy
- Maximum Players: Up to 128 (with Patreon support)
- Sync Method: All players and entities exist for all clients at all times.
- Performance Impact: Higher CPU and bandwidth usage as the server must constantly sync every player’s actions with all others.
- Best For: Smaller roleplay and community servers where constant awareness of all players is necessary.
- Limitations: Can cause performance issues as player count increases, making it inefficient for large servers.
OneSync Infinity (Recommended)
- Maximum Players: Up to 1024 (with Patreon support)
- Sync Method: Uses a culling system, meaning players/entities outside of 300 units (GTA’s in-game distance measurement) aren’t synchronized unless needed.
- Performance Boost: Reduces server load by only syncing nearby players and entities.
- Best For: Large-scale roleplay, freeroam, and dynamic servers where players are spread across a vast map.
- Limitations: Requires proper server-side handling to manage interactions between desynchronized players.
Which OneSync Version Should You Use?
Choosing the right OneSync version depends on your server’s size, gameplay style, and synchronization needs.
| Server Type | Recommended OneSync Version |
|---|---|
| Small roleplay/community servers (up to 128 players) | OneSync Legacy |
| Large roleplay/freeroam servers (128+ players) | OneSync Infinity |
| Servers with spread-out player interactions | OneSync Infinity |
| Servers requiring all players to be continuously aware of each other | OneSync Legacy |
If you’re creating a new server, OneSync Infinity is the recommended choice. It’s future-proof, optimized for larger communities, and helps reduce unnecessary network strain.
Conclusion: Future-Proof Your Server with OneSync Infinity
OneSync has transformed FiveM servers by eliminating GTA Online’s peer-to-peer limitations. While OneSync Legacy remains a viable option for certain server types, OneSync Infinity is the better choice for most modern servers due to its scalability, performance improvements, and enhanced player capacity.
For a stable, optimized, and long-term FiveM experience, OneSync Infinity is the best investment. If your server thrives on continuous global synchronization, OneSync Legacy might still be useful—but for those looking to scale up and create a truly dynamic multiplayer world, Infinity is the way forward.
Choose wisely, optimize your server, and enjoy building an amazing FiveM community!
