How Game Server Hosting Works

Command of the Day

screen -S gameserver

What it does: Launches a detached GNU Screen terminal session allowing persistent game server processes to continue running seamlessly after logging out of SSH.

Multiplayer online gaming connects millions of players across the globe in real-time shared virtual environments. Whether you are running a Minecraft survival realm, a Rust island, a CS:GO arena, or a Palworld guild, the underlying engine making that multiplayer world possible is a dedicated game server.

In this guide, we explore how game server hosting works under the hood, why game server hardware demands differ from web servers, and how to operate your own game server on a RivinCloud VPS.

1. The Client-Server Multiplayer Model

Modern multiplayer games utilize an Authoritative Client-Server Architecture:

Player A (Client) ──[ Keypress / Input Packets (UDP) ]──► ┌──────────────────────────────────────┐
                                                           │   RivinCloud Dedicated Game Server   │
Player B (Client) ──[ Keypress / Input Packets (UDP) ]──► │                                      │
                                                           │ • Physics & Hitbox Calculations      │
Player C (Client) ──[ Keypress / Input Packets (UDP) ]──► │ • World State & Entity Ticks (20/s)   │
                                                           │ • Anti-Cheat State Verification      │
                                                           └──────────────────┬───────────────────┘
                                                                              │
                                                     [ Broadcast Global World Updates (UDP) ]
                                                                              │
                                                                              ▼
                                                           ◄── All Players See Synced State ──►

The Client (Player's PC/Console): Sends only raw user input (e.g., "moved forward", "clicked fire"). It renders 3D graphics and runs client-side prediction.
The Server (RivinCloud VPS): The absolute authority on truth. It computes physics, collision detection, health updates, AI logic, and entity movements, broadcasting the verified world state back to all connected players.

2. The Game Tick Loop (TPS / Tickrate)

Game servers do not run continuous linear code; they execute in rapid discrete cycles called Ticks:

Minecraft: Runs at 20 TPS (Ticks Per Second), meaning the entire world logic is calculated every 50 milliseconds (1000ms / 20 = 50ms).
Competitive Shooters (CS2/Valorant): Run at 64 to 128 Tickrate for hyper-precise hitbox tracking.

If server hardware takes longer than the allocated tick window (e.g., 65ms instead of 50ms in Minecraft), the server experiences Tick Lag (TPS Drop), causing rubberbanding and delayed interactions.

3. Why Game Servers Require High Single-Core CPU Speeds

Unlike web servers (which can distribute thousands of independent HTTP requests across 32 or 64 CPU cores), the main game loop of most game engines (including Minecraft and Unity/Unreal game servers) is predominantly single-threaded.

Because physics, entity interactions, and world logic must be evaluated sequentially in strict lockstep, a CPU with high single-core clock speeds (4.5GHz - 5.5GHz+ Ryzen 9 / Intel Core i9) will vastly outperform an older multi-core server Xeon CPU with 64 slow cores.

4. UDP vs TCP in Game Hosting

Most web traffic uses TCP (which guarantees ordered packet delivery and retransmits lost packets). Game servers rely almost entirely on UDP (User Datagram Protocol):

Low Latency: UDP sends packets immediately without waiting for acknowledgments or establishing handshakes.
No Retransmission Delays: If packet #42 containing player position is lost, retransmitting it 200ms later is useless because packet #45 already has newer coordinates.

5. Running a Game Server on Linux with `screen` or `systemd`

To keep your game server running after you disconnect from your SSH session:

Using GNU Screen:

# 1. Start a named screen session
screen -S gameserver

# 2. Launch your game server
java -Xms4G -Xmx4G -jar paper.jar --nogui

# 3. Detach safely from screen: Press Ctrl + A, then press D

To re-attach to the game server console at any time:

screen -r gameserver

Common Mistakes

Selecting high-core, low-frequency CPUs: Choosing a 2.2GHz multi-core CPU for game hosting will result in severe server lag under player load.
Neglecting Automated World Backups: Game world saves can corrupt during sudden server shutdowns or power interruptions; always schedule daily cron backups.

Troubleshooting

Server lagging with plenty of free RAM: Check single-thread CPU saturation in htop. If Core 0 is at 100%, the main game loop is CPU-bottlenecked.

Best Practices

Host on high-frequency NVMe storage to eliminate world chunk loading stutter.
Deploy in geographic locations closest to your player community to minimize network ping.

Frequently Asked Questions

What is the difference between a VPS and a Game Hosting Panel?

A Game Hosting Panel (like Pterodactyl) provides a web interface for managing game instances, but runs on top of a Linux VPS or Dedicated Server. A VPS gives you full root access to customize OS kernel settings, ports, and modloaders.

Conclusion

Game server hosting combines high single-thread CPU performance, low-latency UDP networking, and fast NVMe storage. Spin up your optimized game server on RivinCloud VPS today!
