Hytale RAM Requirements in 2026 (Minimum vs Recommended)

Before you assume something is “wrong”, compare your setup to what players are realistically using.

Minimum RAM (Playable on low settings)

8 GB RAM (with a dedicated GPU)
12 GB RAM (if you’re on integrated graphics)

Recommended RAM (Smooth gameplay for most players)

16 GB RAM

If you stream or multitask while playing

If you play Hytale while running Discord, Chrome, OBS, and other apps:

32 GB RAM is ideal

💡 Important: On an 8 GB PC, the OS + background apps can force heavy disk swapping, which feels like “Hytale lag” even when the game itself is not broken.

Hytale Server RAM Requirements (The Real Story)

Server RAM needs vary wildly depending on:

Player count
Exploration (players spreading out)
View distance
Mods / scripts

A rough starting point for planning:

Up to 4 players: 4 GB RAM
5–10 players: 6–8 GB RAM
10–20 players: 8–10 GB RAM
20–40 players: 10–16 GB RAM
Heavily modded / large networks: 16–32 GB+

Most hosts warn that view distance and mods matter more than raw player count.

Why Is Hytale Using So Much RAM? (Main Causes)

1) View Distance Loads Too Much World Data

Hytale defaults to a large view radius, meaning more of the world is loaded and simulated at once.

That consumes RAM for:

Terrain/voxel data
Entities (NPCs, mobs, dropped items)
AI behavior states
Lighting & effects
Collision & physics

The most important server setting: `MaxViewRadius`

On servers, the biggest memory lever is usually this:

"MaxViewRadius": 32

When this value is high:

More chunks stay loaded per player
Players spreading out multiplies RAM usage
Garbage collection gets heavier

✅ If you fix only one thing on a Hytale server, fix this.

2) Early Access Optimization Isn’t Finished Yet

Early access games often ship with:

Memory leaks
Cache issues
Worldgen spikes
Performance degradation over time

Signs you’re hitting a memory leak / fragmentation issue

RAM usage slowly rises over time
Stutters get worse after 1–3 hours
Restarting the game/server instantly improves performance

3) Mods and Scripts Can “Lock” RAM Usage

Hytale launched with modding support — which is great… but also dangerous for performance.

Unoptimized mods can:

Keep large caches in memory forever
Keep areas permanently loaded
Spawn too many entities
Run heavy scripts every tick

If your server runs fine in vanilla but RAM explodes after adding mods, the cause is almost always:

Too many overlapping mod features
Poorly written scripts
Global systems that never unload

4) AI, Entities, and World Complexity Cost Memory

Compared to older block games, Hytale leans harder into:

Richer NPC behaviors
More complex combat systems
Higher detail assets and animations
Persistent RPG-like systems

That means:

More memory per entity
More system state kept active in RAM
Bigger world structures in memory

So yes — Hytale can legitimately use more RAM than you expect, especially in busy areas.

5) Server-Side Background Services Also Use RAM

Your dedicated server usually runs more than just the game:

OS caching and filesystem buffers
Server panel agents
Security tools
Backups
Monitoring processes

This reduces the RAM available for the Java server process, even before the game starts.

How to Reduce Hytale RAM Usage (PC / Client Fixes)

Step 1) Close Background Apps That Eat Memory

Before changing Hytale settings:

Close browsers (especially 20+ tabs)
Disable overlays (Discord, GPU overlays)
Close launchers you don’t need
Disable unnecessary startup apps

✅ On 8–16 GB machines, this can free 1–3 GB RAM.

Step 2) Lower View Distance and Graphics Settings

This is the biggest win for both stuttering and RAM pressure.

Recommended actions:

Reduce view distance until stable
Lower shadows / particles / post-processing
Disable heavy effects if needed

💡 Lowering view distance reduces:

Loaded world size
Active entities
CPU spikes and memory pressure

Step 3) Optimize Windows for Gaming

On Windows 10/11:

Enable Game Mode
Use a High Performance power plan

This prevents CPU down-clocking and reduces stutters that often look like “RAM issues.”

Step 4) Update Drivers and OS

Outdated GPU drivers can cause:

rendering stalls
memory inefficiencies
stuttering / lag spikes

Always stay current with NVIDIA / AMD / Intel drivers.

Step 5) Know When You Need More RAM

If you’ve done everything above and still struggle:

Upgrading from 8 GB → 16 GB is the biggest improvement for most players.
32 GB is best if you stream or multitask heavily.

How to Reduce Hytale Server RAM Usage (Server Fixes)

Step 1) Reduce `MaxViewRadius` (Biggest Server RAM Fix)

Stop the server
Open config.json
Find:

"MaxViewRadius": 32

Change it based on your RAM:

4 GB RAM → 8
8 GB RAM → 12
16 GB RAM → 16
16 GB+ → 24–32 (only if stable)

✅ For most servers, 16 is the best balance between visibility and performance.

Step 2) Set Smart Java Heap Limits (`-Xms` and `-Xmx`)

Don’t give Java all your RAM. Use a fixed heap.

Small friends server (2–6 players)

java -Xms4G -Xmx4G -jar HytaleServer.jar --assets Assets.zip

Small community (8–16 players)

java -Xms6G -Xmx6G -jar HytaleServer.jar --assets Assets.zip

Larger / modded server (20+ players)

java -Xms10G -Xmx10G -jar HytaleServer.jar --assets Assets.zip

✅ Best practice:

Leave 2–4 GB free for OS + caching
Increase -Xmx only if you see consistent memory pressure

Step 3) Keep Player Spread in Mind

RAM usage doesn’t only depend on player count.

It also depends on where players are.

If 10 players are all in one town → RAM usage is stable.

If 10 players spread across the world → RAM usage can spike hard.

✅ Fix this by lowering view distance before upgrading RAM.

Step 4) Audit and Remove Heavy Mods

Use this process:

Start vanilla (measure baseline RAM)
Add mods one-by-one
Remove any mod that:
- keeps areas always loaded
- spawns too many entities
- runs complex logic every tick

Light QoL mods usually have minimal impact.

Big RPG frameworks or global systems are often the worst offenders.

Step 5) Optimize Other Server Settings

Example config structure:

{
  "ServerName": "My Hytale Server",
  "MaxPlayers": 20,
  "MaxViewRadius": 16,
  "LocalCompressionEnabled": true,
  "ConnectionTimeouts": {
    "JoinTimeouts": {}
  },
  "RateLimit": {},
  "Mods": {}
}

Consider:

Lowering MaxPlayers if RAM is tight
Enabling compression where supported
Using timeouts/rate limits to reduce wasted resources

Step 6) Monitor RAM Over Time (And Restart if Needed)

Track:

RAM usage trend over hours
CPU spikes during world generation
GC pauses

If performance degrades until a restart…

That’s common in early access.

✅ Until optimization patches improve memory handling:

Schedule restarts every 12–24 hours

Quick Hytale RAM Calculator (Server Planning)

Use this simple planning model:

Baseline: 4 GB for the first 4 players
Add: +1 GB per additional player (safe buffer)
Mods: multiply by 1.5× to 2× for heavy modpacks
Large worlds / always-loaded systems: add 2–4 GB

Examples

6–8 friends, light mods → 6–8 GB
20-player community server, some mods → 10–16 GB
50-player heavily modded network → 16–32 GB+

FAQ: Hytale RAM, Memory Leaks, and Performance (2026)

Does Hytale use more RAM than Minecraft?

Yes — Hytale currently targets richer AI systems, larger default view distances, and more complex gameplay mechanics than vanilla Minecraft, so it often uses more RAM per player and world area.

Is 8 GB RAM enough for Hytale in 2026?

Technically yes (minimum for dedicated GPUs), but it leaves very little headroom for Discord, browsers, or background apps. 16 GB is strongly recommended.

How do I know if I have a Hytale memory leak?

Signs include:

RAM usage steadily climbs the longer you play
Stutters get worse over time
Crashes or “out of memory” errors

If restarting fixes everything instantly, you’re likely hitting early access leak behavior.

What is the best `MaxViewRadius` for a Hytale server?

For most servers:

16 = best overall balance
8–12 = low-RAM / budget servers
24–32 = only on high-end hardware with lots of RAM

When will Hytale RAM usage improve?

Early updates are expected to prioritize technical improvements and performance fixes.
