How to Configure OneSync Legacy vs Infinity in FiveM | EUGameHost

Choose the right OneSync mode for your FiveM server to improve player sync, slot capacity, and network performance.

This is especially important for servers planning to grow beyond standard player limits.

Difficulty: Intermediate
Time Required: 8 Minutes

What Is OneSync?

OneSync is FiveM’s networking system that allows servers to go beyond the original GTA V player limit.

It improves:

• player synchronization
• entity streaming
• slot capacity
• network performance
• distance-based sync

OneSync Modes

Legacy

Best for older servers and legacy scripts.

Capacity: Up to 48 players

Best for:

• older resources
• older frameworks
• legacy ESX servers
• older scripts from 2017–2019

In Legacy mode, player data is synced more globally.

This means more data is sent to more players.

Infinity (Recommended)

Best for modern servers.

Capacity: Higher slot counts

Best for:

• modern frameworks
• optimized scripts
• 64+ slot servers
• better performance

Infinity uses distance-based streaming.

Players only receive nearby entity data, which greatly improves performance.

This is the recommended option for most servers.

How to Enable OneSync Infinity

Open your server.cfg.

Add:

set onesync on

This enables OneSync Infinity.

Restart Your Server

Restart your server from the EUGameHost Game Panel.

The new sync mode will apply after restart.

When to Use Legacy

Use Legacy only if you are running older scripts that depend on global player sync.

Examples:

• outdated inventory systems
• old ESX resources
• older menu scripts

When to Use Infinity

Use Infinity if you want:

• better performance
• larger player counts
• modern framework support
• less network load

For most servers, this is the best option.

Important: Check Framework Compatibility

Before switching, make sure your framework is updated.

Common examples:

• QB-Core
• ESX Legacy

Older versions may cause:

• player desync
• invisible players
• ghost entities
• inventory issues

Best Practice

For all modern EUGameHost servers, we recommend:

set onesync on

Only use Legacy if a specific older script requires it.
