Abiotic Factor Server Requirements 2025
Running a smooth Abiotic Factor server requires appropriate hardware for your player count. This guide breaks down the recommended specifications for different server sizes.
6 Players (Recommended)
Official supported limit. Balanced gameplay, stable performance.
12 Players (Extended)
Requires good hardware. Resources deplete faster.
24 Players (Maximum)
Maximum supported. Powerful hardware required. Balance issues likely.
Hardware Requirements by Player Count
| Configuration | 6 Players | 12 Players | 24 Players |
|---|---|---|---|
| CPU | 4 cores @ 2.5 GHz i5-8400 / Ryzen 5 2600 |
6 cores @ 3.0 GHz i7-9700 / Ryzen 7 3700X |
8+ cores @ 3.5 GHz i9-9900 / Ryzen 9 3900X |
| RAM | 8 GB | 16 GB | 32 GB |
| Storage | 10 GB SSD | 15 GB NVMe SSD | 20 GB NVMe SSD |
| Network | 50 Mbps upload | 75 Mbps upload | 100+ Mbps upload |
| Recommended OS | Windows 10/11 64-bit Ubuntu 20.04+ LTS |
Windows Server 2019 Ubuntu 22.04 LTS |
Windows Server 2022 Ubuntu 22.04 LTS |
Minimum System Requirements
For a basic 6-player server, these are the absolute minimum specifications:
| Component | Minimum Specs |
|---|---|
| CPU | 4 physical cores @ 2.0 GHz |
| RAM | 4 GB (8 GB recommended) |
| Storage | 10 GB HDD (SSD recommended) |
| Network | 25 Mbps upload |
| OS | Windows 10 64-bit / Linux 64-bit |
Important: Minimum requirements will result in decreased performance, lag spikes, and potential server crashes. We strongly recommend following the recommended specifications for stable gameplay.
Network Requirements
Upload Speed
- 6 players: Minimum 50 Mbps upload
- 12 players: Minimum 75 Mbps upload
- 24 players: Minimum 100 Mbps upload
Bandwidth Calculation
Each player requires approximately 8-12 Mbps of bandwidth for smooth gameplay. Calculate your needs:
Total Upload Speed Needed = Players × 10 Mbps (average)Port Requirements
| Port | Protocol | Purpose | Required |
|---|---|---|---|
| 7777 | UDP | Game Port | Yes |
| 27015 | UDP | Query/Discovery Port | Yes |
Storage & Performance
Storage Type Impact
| Storage Type | Loading Time | Performance | Recommended |
|---|---|---|---|
| HDD | Slow (30+ seconds) | Poor | No |
| SATA SSD | Moderate (10-15 seconds) | Good | Yes |
| NVMe SSD | Fast (3-5 seconds) | Excellent | Highly Recommended |
💾 Storage Growth
Abiotic Factor world files grow as players progress. Plan for 2-3x initial storage requirements:
- Initial world: ~2-3 GB
- After 50+ hours: ~5-8 GB
- Heavily explored worlds: ~10-15 GB
CPU Performance Considerations
Core Count vs. Clock Speed
- Single-thread performance is crucial for Abiotic Factor servers
- Clock speed (GHz) matters more than core count for base performance
- Additional cores help with player scaling and background processes
Recommended CPU Architecture
| Performance Tier | Intel | AMD |
|---|---|---|
| Entry (6 players) | i5-8400 / i5-10400 | Ryzen 5 2600 / 3600 |
| Mid (12 players) | i7-9700 / i7-10700 | Ryzen 7 3700X / 5700X |
| High (24 players) | i9-9900 / i9-11900 | Ryzen 9 3900X / 5900X |
RAM Usage Breakdown
- Base server: 2-4 GB
- Per player: ~0.5-1 GB
- World data: 1-3 GB (varies by exploration)
- Overhead: 1-2 GB (system, network)
Formula: RAM Needed = 4 GB (base) + (Players × 1 GB)
Operating System Considerations
Windows vs. Linux
| Aspect | Windows | Linux |
|---|---|---|
| Performance | Good (native) | Better (lightweight) |
| Setup Difficulty | Easy (GUI) | Moderate (command line) |
| Resource Usage | Higher overhead | Lower overhead |
| Maintenance | Auto-updates | Manual control |
| Cost | Licensing required | Free (most distros) |
| Recommended For | Beginners | Experienced admins |
Testing Your Setup
Stress Test Commands
# Windows Task Manager
# Monitor CPU, RAM, and Network usage during gameplay
# Linux htop
sudo apt-get install htop
htopPerformance Indicators
- CPU Usage: Below 80% under load
- RAM Usage: 70-85% utilization is ideal
- Network: Consistent upload speed without spikes
- Server Tick Rate: Should remain stable at 20-30 ticks per second
Upgrading Your Server
If you experience issues, consider these upgrades in order of priority:
- Upgrade to SSD (HDD → SATA SSD → NVMe SSD)
- Increase RAM (8 → 16 → 32 GB)
- CPU Upgrade (focus on single-thread performance)
- Network Upgrade (faster upload speed)
