Understanding Why Local Hosting Fails for 7 Days to Die
7 Days to Die is an incredible game, but it is also one of the most resource-heavy survival titles ever created. The deeper you go into the late game, the more enemies spawn, the more structures load, the more chunks generate, and the more strain the game places on the machine hosting the world. While many players try to host a world on their home PC, they eventually hit a wall—lag, rubberbanding, FPS drops, stuttering, corrupted worlds, and even total crashes.
This isn’t because your PC is “bad.”
It’s because 7 Days to Die was never designed to be hosted reliably from a personal computer, especially when multiple players are involved.
In this article, you’ll learn the real technical reasons why local hosting performs poorly, the limitations players never notice until too late, and the correct solution for a smooth, stable, 24/7 multiplayer world: a dedicated 7 Days to Die server hosted externally, such as through GGServers (use code KB30 for 30% off).
Let’s break it down.
The Truth About How 7 Days to Die Uses Hardware
Many players think that if their PC can run 7 Days to Die, it can also host 7 Days to Die. Unfortunately, that couldn’t be further from the truth. Running the game and hosting the world in the background are two completely different loads on your system.
Here’s why:
1. 7 Days to Die Is Extremely CPU-Intensive
The game uses Unity, but unlike many Unity titles, 7DTD handles world generation, AI pathfinding, physics, dynamic destruction, chunk management, and lighting calculations directly on the CPU. Even with modern CPUs, these operations hit hard.
When you host locally, your CPU must handle:
- Your own game client
- The server simulation
- Horde AI
- Physics for all players
- Vehicles, zombies, entities
- Chunk loading for everyone
- Player actions
- Tasks from mods and modlets
- Background world updates
This creates constant CPU spikes that lead to stutter, lag, delayed zombie attacks, and even slow chunk loading for your friends.
2. 7DTD Uses a Single Thread for Critical Tasks
Although the game can technically use multiple cores, the core simulation loop is single-threaded, meaning even high-end CPUs can bottleneck when hosting the server and running the game at the same time.
Your PC simply can’t keep up—especially during Horde Night.
3. Memory Leaks and Long Load Times Worsen Over Time
7 Days to Die has memory-related behaviors that gradually increase RAM usage, especially when worlds get older. Hosting on your PC means that:
- Long sessions create memory bloat
- Switching biomes loads huge asset bundles
- The server process grows the longer it runs
- Old chunks remain in RAM longer
- Mods increase memory footprint dramatically
On a dedicated hosting machine like those at GGServers, there is isolated RAM and proper allocation that avoids this.
4. GPU Load Doesn’t Matter for Hosting
A common misconception:
“My GPU is strong, so I should be fine.”
No.
Although your GPU helps you run the game, it does almost nothing for server performance. The server engine relies primarily on CPU + RAM. This is why players with RTX 4090 cards still struggle when hosting locally.
Your GPU is irrelevant.
Your CPU and RAM are overwhelmed.
Internet Upload Speed: The Silent Destroyer of Local Hosting
Download speed doesn’t matter for hosting.
Upload speed is everything.
Most home connections have terrible upload bandwidth—often between 5–25 Mbps.
But hosting players requires:
- Constant position updates
- Chunk transfers
- Zombie AI sync
- Vehicle sync
- Combat events
- Loot data
- Terrain destruction and shape updates
- Block stability calculations
- Real-time horde pathfinding
Even 2–4 players can overwhelm a home connection if multiple devices are connected or if someone is streaming, downloading, or watching YouTube.
With low upload speed, players will experience:
- Rubberbanding
- Delayed zombie attacks
- Teleporting enemies
- Blocks appearing/disappearing
- Falling through the map
- Vehicles glitching into the ground
GGServers solves this because their 7 Days to Die hosting runs on high-speed fiber networks optimized for low latency and high upload throughput—the exact conditions 7DTD requires.
Local Hosting Makes You the Bottleneck for Everyone
If your PC struggles, everyone struggles.
If your internet cuts out, everyone disconnects.
If your power flickers, the entire world risks corruption.
If your PC sleeps, the server goes offline.
If your CPU spikes, zombies delay for everyone—leading to deaths.
This means your hardware becomes your entire group’s vulnerability.
Playing on a self-hosted local world is never stable, and your friends will feel the consequences every time something minor happens on your end.
A dedicated server removes you as the bottleneck entirely.
The Hidden Causes of Lag When Hosting Yourself
Even if your PC seems “good enough,” these overlooked factors destroy performance:
Local World Saves
Saving world data to consumer SSDs or HDDs is dramatically slower than on enterprise-grade hardware.
Background Programs
Chrome tabs
Windows updates
Steam downloads
Antivirus scans
Discord
Spotify
All of these steal resources from the server.
Wi-Fi Hosting
If your PC is on Wi-Fi, hosting performance drops instantly.
NAT Issues & Port Forwarding
Players struggle with:
- Port 26900–26903 not opening
- Firewall blocking connections
- Router firmware bugs
- ISP-level port blocking
- Double NAT problems
This alone is enough to make hosting painful.
Temperature Throttling
7DTD stresses your CPU, which heats up your system. When temperatures spike, your CPU throttles down, causing lag spikes.
Why the Game Gets Worse Over Time on Local Hosts
As days pass and the world grows, the server becomes more demanding:
- More structures
- More zombies
- More loot containers
- Increased base complexity
- More map exploration
- Larger save files
- More blood moon data
- More player-built objects
By Day 40–60+, local-hosted worlds become almost unplayable—with players experiencing frame drops, lag, and stuttering even if the game was smooth at the beginning.
World growth exposes the limits of local hosting.
Dedicated servers do not have this problem because they’re designed to handle long-term worlds with stable hardware and consistent uptime.
Why Dedicated Hosting With GGServers Fixes All These Issues
Here’s what happens when you switch to a GGServers 7 Days to Die server instead of hosting on your PC:
1. Your CPU No Longer Has to Run the Server
This alone fixes:
- FPS drops
- Lag
- Stuttering
- Slow chunk loading
- Delayed zombie movement
- Horde Night performance drops
Your PC only runs the client—not the entire world simulation.
2. 24/7 Uptime, Even When You’re Offline
Your base keeps running.
Your world keeps ticking.
Your friends can join anytime.
Horde Night remains consistent.
Crafting and smelting continue even if your PC is off.
3. Zero Port Forwarding or Network Configuration
Just click “Start Server.”
No router issues.
No NAT issues.
No firewalls to fight.
4. Enterprise-Level Hardware
GGServers runs your 7DTD server on:
- High-speed NVMe storage
- Modern Ryzen / Intel CPUs
- Fiber backbone networks
- Optimized data centers
- Protected networks
These are designed for server workloads—something your home PC cannot replicate.
5. Global Locations for Low Latency
Choose from worldwide server locations for the lowest ping for your group.
6. Full Mod Support
Install modlets, overhauls, or total conversions easily:
- Darkness Falls
- Undead Legacy
- War of the Walkers
- KingGen maps
- Custom POIs
Dedicated hosting handles mod load far better than local hosting.
7. Automatic Backups
Prevent world corruption—one of the biggest risks of local hosting.
8. FTP Access & Control Panel
You get full control of your world files, configurations, and mod folders.
9. Affordable Pricing

This is the professional solution every major community uses.
Who Should Switch to a Dedicated Server?
You must switch to a hosted server if:
- You play with 2+ friends
- You build large structures
- You play Horde Night regularly
- You use mods
- Your world is older than Day 20
- Your base is complex
- Your friends complain about lag
- Your PC starts to stutter
- You host on Wi-Fi
- You want 24/7 uptime
- You want the world to progress while you’re offline
If any of these describe your situation, your PC simply cannot handle the load reliably.
A hosted solution is the only stable way to play.
Final Thoughts: Your PC Isn’t the Problem—The Game Is
7 Days to Die is a brilliant but extremely heavy game.
Local hosting may work for the first hour or two, but once the world grows, the game becomes too demanding for personal hardware. Your PC was not built to serve as a 24/7 dedicated server.
The correct way to host 7 Days to Die for friends, modpacks, communities, or long-term progression is through a proper hosting provider.
