What Are FiveM Server Variables?

Server variables, often called “convars” (configuration variables), are key-value pairs that control various aspects of your FiveM server’s behavior. These variables influence everything from network bandwidth and resource allocation to script execution and player limits.

In short:

FiveM server variables are settings that define how your server operates, impacting performance, customization, and player experience.

Understanding and managing these variables is critical for server owners, developers, and admins who want to maximize uptime, reduce lag, and provide a rich, stable gaming environment.

Why Server Variables Matter for FiveM Performance

Optimizing FiveM server variables is not just an advanced tweak—it’s a foundational step for anyone serious about running a successful server. Here’s why:

• Performance Control: Properly configured variables minimize lag, reduce resource waste, and ensure smooth gameplay.
• Customization: Server variables allow you to tailor scripts and mods, creating unique experiences for your community.
• Security and Stability: Tweaking the right variables helps defend against exploits and unexpected crashes.

According to FiveM Official Documentation, server variables are the backbone of server management, directly affecting everything from tick rates to script execution.

Key FiveM Server Variables You Must Know

Let’s break down the most important server variables every FiveM server owner should understand. Mastering these will set you apart from the competition and help you deliver a top-tier multiplayer experience.

1. sv_maxclients

Definition:

Controls the maximum number of players allowed on your server simultaneously.

• Default: 32
• Best Practice: Set this value based on your server’s hardware and bandwidth capacity. Overloading can cause lag and crashes.

2. onesync_enabled

Definition:

Enables OneSync, FiveM’s advanced networking framework for higher player counts and better performance.

• Options: true or false
• Tip: Enabling OneSync is crucial for servers aiming to host more than 32 players. It unlocks features like entity streaming and improved synchronization.

3. sv_scriptHookAllowed

Definition:

Determines whether players can use client-side scripts (ScriptHook).

• Options: true or false
• Security Note: Disabling ScriptHook (false) is recommended for public servers to prevent cheating.

4. sv_enhancedHostSupport

Definition:

Improves compatibility for certain hosting environments.

• Options: true or false
• When to Use: Enable if you’re running on a host with unique networking setups.

5. sv_hostname

Definition:

Sets your server’s name as it appears in the FiveM server list.

• Best Practice: Use a clear, descriptive hostname to attract players and improve discoverability.

How to Optimize FiveM Server Variables for Peak Performance

Optimizing server variables isn’t about guesswork—it’s about making data-driven decisions based on your community’s needs and your server’s capabilities. Here’s a step-by-step approach:

Step 1: Assess Your Hardware and Network

• CPU & RAM: Know your limits. High player counts and complex scripts require more resources.
• Bandwidth: Ensure your connection can handle the expected traffic.

Step 2: Set Core Variables

• Adjust sv_maxclients to match your hardware.
• Enable onesync_enabled for large servers.
• Set sv_scriptHookAllowed to false for public servers.

Step 3: Monitor and Adjust

• Use FiveM’s built-in monitoring tools and logs to track performance.
• Adjust variables like onesync_population and sv_threaded_client_net for advanced tuning.

Step 4: Test Custom Scripts

• Always test new scripts in a controlled environment.
• Use variables to limit resource usage and avoid script conflicts.

Step 5: Stay Updated

• Follow FiveM’s changelogs for new variables and updates.
• Join community forums and Discords for best practices.

Best Practices for Custom Scripts and Resource Management

Custom scripts are at the heart of every unique FiveM server. However, poorly managed scripts can lead to lag, crashes, and security vulnerabilities. Here’s how to optimize script performance using server variables:

1. Limit Resource Usage

• Use the ensure and start commands to control which scripts load.
• Monitor script performance with the resmon tool.

2. Isolate and Test New Scripts

• Always test on a development server before deploying to production.
• Use variables to restrict script permissions and resource allocation.

3. Update Regularly

• Keep scripts and dependencies up to date.
• Leverage FiveM QBCore and Qbox Scripts for optimized, community-tested solutions.

4. Prevent Exploits

• Disable unnecessary client-side scripting.
• Use FiveM Anticheats for added protection.

5. Optimize Entity Streaming

• Fine-tune variables like onesync_population to balance performance and immersion.
• Use high-quality FiveM Maps and MLOs that are optimized for server performance.

Common Mistakes to Avoid with FiveM Server Variables

Even experienced server owners can fall into these traps:

• Overloading Player Count: Setting sv_maxclients too high for your hardware leads to lag and disconnects.
• Ignoring Security: Leaving ScriptHook enabled or failing to use anti-cheat solutions exposes your server to exploits.
• Neglecting Updates: Outdated scripts and server builds can cause compatibility issues and crashes.
• Forgetting Backups: Always back up your server configuration before making major changes.
