Optimizing your FiveM server CFG is crucial for delivering a seamless multiplayer experience. The right configuration settings can spell the difference between lag-filled frustration and ultra-smooth, immersive gameplay. Whether you’re managing a thriving roleplay community or launching a brand-new FiveM server, mastering your CFG unlocks performance, stability, and player retention. In this deep-dive guide, you’ll learn how to fine-tune your FiveM server config settings for optimal performance, reduce lag, and provide the flawless gameplay your players expect.
Why FiveM Server CFG Optimization Matters
Your server.cfg file controls the heartbeat of your FiveM server. Every line, from basic variables to advanced tweaks, directly influences server stability, resource management, and resource synchronization. For server owners and administrators, understanding how to optimize these settings is foundational.
High-quality, optimized server.cfg files are key to:
- Reducing latency and in-game lag.
- Minimizing downtime, crashes, or desyncs.
- Scaling performance for higher player counts.
- Enabling feature-rich scripts, EUP packs, vehicles, and immersive maps.
An outdated or poorly structured configuration leads to avoidable headaches. Fortunately, by following a structured approach outlined below, you’ll avoid the most common pitfalls and lay the groundwork for a thriving community.
Core FiveM Server.cfg Settings Explained
Understanding the core variables is step one toward advanced CFG optimization. Here are the primary sections and their impact:
Essential Variables
- Hostname: The public-facing name of your server. Use clear, concise branding to stand out in the server list.
- Max Players (
slots): Set realistically—overestimating can tax your server hardware and degrade performance. - Endpoint Add_Port: Set correct listening ports for network stability.
Resource Start Order
The load order of scripts and mods impacts both security and efficiency. Always:
- Load framework scripts (like ESX or QBCore) before custom resources.
- Prioritize security scripts next (e.g., anticheat solutions).
- Queue in jobs, vehicles, and cosmetic mods last.
Network and Sync Settings
Optimize the following for lag-free interactions:
- sv_maxclients: Mirror your realistic max concurrent players.
- onesync: Must be enabled for servers with >32 players. Improves entity synchronization.
- sv_minclientcap: Restrict minimum client requirements as needed.
For more script, vehicle, or map resources, check the FiveM Mods and Resources marketplace for performance-optimized packages.
Best Practices for CFG Performance Tuning
1. Align Slots with Hardware
Never set your player slot count higher than your server can reliably support. Practice a “less is more” approach:
- Monitor CPU and RAM: Use external monitoring as your population scales.
- If running resource-heavy scripts or high-res FiveM Vehicles, consider lowering slots for stability.
2. Enable Onesync for Large Communities
FiveM’s Onesync framework is essential for servers hosting more than 32 players. It improves:
- Real-time sync of players, vehicles, and props.
- Support for custom jobs, scripts, and large maps—like FiveM Maps and MLOs.
Activate Onesync with:
onesync on
in your CFG. This unlocks support for advanced FiveM Scripts and larger map assets without sacrificing performance.
3. Optimize Streaming Settings
Maintain a balance between graphical quality and player connection speeds:
- sv_maxclients: Set to your capacity.
- sv_maxuplink: Restrict excessive bandwidth usage.
For servers with custom FiveM EUP and Clothes or heavy use of FiveM Objects and Props, always monitor file sizes. Large assets increase client download times and can introduce stutter if not managed properly.
4. Protect with Anticheat and Security Plugins
Add trusted anticheat solutions to your CFG load order. This keeps player actions fair and protects against exploits:
- Always load FiveM Anticheats resources right after your main framework.
- Update regularly and monitor changelogs from authoritative sources like FiveM Official.
5. Schedule Automatic Restarts
All high-population servers benefit from planned restarts:
- Use tools or scheduler scripts to reboot your server during off-peak hours.
- Automatic restarts clear RAM, resolve resource leaks, and keep performance crisp.
- Announce restarts in advance using FiveM Discord Bots for better player communication.
Advanced Configurations for Experienced Server Admins
Fine-tuning Network Rates
Delve deeper into network optimization by adjusting resource settings:
- rate: Controls data transfer rate. Increase cautiously for higher player counts, but benchmark carefully.
- sv_networkRate: Fine-tune based on server tickrate and connection quality. For typical roleplay or economy servers, balanced rates maintain smooth gameplay.
Pro Tip: Review your own bandwidth and player feedback after making changes.
Prioritizing Essential Scripts and Mods
Order matters! Make sure:
- FiveM Frameworks like QBCore or ESX load first.
- Utility and security scripts follow.
- Interactive FiveM Marketplace resource mods, jobs, and events are last.
This reduces boot-time errors and ensures dependencies load in sequence.
Streamline Resources
- Regularly remove unused or heavy resources.
- Audit for script inefficiencies—often, a single problematic mod or map can degrade your whole server.
- Evaluate new additions from trusted sources like the FiveM Store before deploying to your live environment.
Example Optimized FiveM CFG Structure
Here’s a snippet for reference (adjust values to fit your hardware and community):
hostname "My Immersive RP Server"
sv_maxclients 64
onesync on
endpoint_add_tcp "0.0.0.0:30120"
start mysql-async
start es_extended
start essentialmode
start anticheat
start cars
start eup
start customjobs
sv_scriptHookAllowed 0
sv_endpointprivacy true

Troubleshooting Common CFG Issues
Even experienced admins encounter CFG headaches. Address these common issues proactively:
- Server not showing in list? Check for port forwarding, correct
endpoint_addvalues, and proper firewall settings. - In-game lag/packet loss? Audit scripts for inefficiency, verify
onesyncstatus, and match slot count to hardware. - Resource load errors? Double-check resource spelling and dependents in your load order.
For more advanced diagnosis, refer to guides at Rockstar Games for system requirements and compatibility.
