Hytale Server sizing & resource guide
This guide lets you figure out how much RAM and CPU power your Hytale server will likely need.
TL;DR - Standard RAM sizes for common scenarios
The following table contains some of the most common Hytale server scenarios if you just want to get a rough idea:
| Use case | RAM (est.) | CPUs | Notes |
|---|---|---|---|
| Small private world, 2–5 players | ~4–6 GB | 2–3 Cores | Light exploration, limited world size |
| Friends server, ~10 players | ~6–8 GB | 3–4 Cores | More terrain, mobs, and combat |
| Community or modded server | ~8–12 GB | 4–6 Cores | Content packs, scripts, databases |
| Large world or many active players | ~12–16 GB | 6–8 Cores | Heavy simulation, AI, world generation |
How Hytale uses resources
Hytale runs a continuous server-side simulation of the world: creatures, physics, combat, terrain, scripts, and player actions all happen on the server.
Unlike lobby-based games, most of Hytale’s gameplay logic lives on the server, which makes proper sizing important.
RAM usage patterns
Hytale keeps the world, entities, scripts, and player data in memory.
More terrain, mobs, NPCs, and mods directly increase memory usage.
| Workload type | Description | Typical RAM behaviour |
|---|---|---|
| Small private world | Few players, limited exploration | Memory grows slowly with world size |
| Active exploration | Players spread out, new terrain loaded | RAM increases as chunks and assets stay cached |
| Mods & content | Custom mobs, items, scripts, systems | Each mod increases baseline memory usage |
| Large community | Many players, entities, worlds, and automation | Memory scales with loaded entities and active simulation |
CPU resources
Hytale uses CPU for:
- AI and mob behaviour
- Physics and combat
- World simulation
- Chunk generation
- Scripting and mods
- Networking and databases
Because of this:
- High single-core speed is crucial for smooth gameplay
- Extra cores help with background tasks, mod logic, chunk generation, and I/O
HypeServ’s Ryzen 9 CPUs are tuned for exactly this kind of real-time simulation workload. Giving you the best of both single-core speed and multi-core handling for other server tasks.
(This is what all HypeServ packages follow by default.)
Putting it all together
Here’s a practical sizing reference combining RAM and CPU expectations:
| Use case | RAM (est.) | CPUs | Notes |
|---|---|---|---|
| Small private world, 2–5 players | ~4–6 GB | 2–3 Cores | Low entity and world load |
| Friends server, ~10 players | ~6–8 GB | 3–4 Cores | Moderate exploration and combat |
| Community or modded server | ~8–12 GB | 4–6 Cores | Content packs, scripts, databases |
| Large public world | ~12–16 GB | 6–8 Cores | Heavy AI, mobs, and world simulation |
Common pitfalls & how to avoid them
Allocating too little RAM
If allocated memory is too low, Hytale can’t keep world data, entities, and scripts loaded.
Typical console errors include:
OutOfMemoryError
This usually leads to freezes, disconnects, or crashes.
What you can do to avoid this: Increase RAM allocation so the server has enough memory for the world and entities.
Allocating too little CPU
When the server can’t keep up with real-time simulation, players will see rubber-banding, delayed combat, and lag.
Hytale relies heavily on continuous simulation, so insufficient CPU causes immediate gameplay issues.
What you can do to avoid this: Increase CPU cores or move to a higher-performance plan.
Summary
Jokes on you, this is not actually the summary! We’ve put it at the top so most people get to the important bits immediately.
