Rule-of-thumb: around 0.5 GB per player, then add overhead for the game, OS, and mods.

Overhead (GB)

Reality-check it with a stress session: spread players across towns, drive, enter interiors, fight, and loot at the same time.

Symptom

Hard Cap vs Safe Cap (The One Distinction That Matters)

On paper, MaxPlayers is just a setting: 1–100 (default 32). In practice, your “real” max is the moment map streaming and desync turn a co-op night into rubber-banding.

• Hard cap: what the setting allows you to type.
• Safe cap: what your server can run without turning into a lag museum.

The Numbers That Matter

Community-posted server option metadata for MaxPlayers commonly shows:

• Minimum: 1
• Maximum: 100
• Default: 32
• Warning: player counts above 32 can cause poor map streaming and desync.

Raising Slots Safely (The “Slot Ladder” Mindset)

Slots behave like a progression system. Prove stability at low population, then climb in small steps.

• Stage 1 (8–12): prove stability with your mod list and map settings.
• Stage 2 (16–24): introduce “spread pressure” (players in different cells).
• Stage 3 (32): where many servers start showing warning signs.
• Stage 4 (40+): performance engineering, not casual hosting.

Can I set max players above 100?

Vanilla server option metadata commonly documents MaxPlayers as 1–100. Above that is unofficial territory: expect instability and extra debugging.

Why is 32 the default if 100 is allowed?

Defaults are about “works for most people,” not “how far can we push the engine.” The same metadata that shows max 100 also warns that going above 32 can lead to streaming/desync issues.

What should I set for a friends-only server?

Set MaxPlayers to the number of humans you actually expect online at once, plus a tiny buffer. For most friend groups, 8–12 is the sweet spot.

What should I set for Build 42 multiplayer?

Treat it as a stress test. Dedicated servers are advised to stay under ~20 players right now, and smaller is smarter if you want a smooth night.

Does raising MaxPlayers increase zombie count or loot competition?

Not automatically—but more players means more looting, more noise, more movement, and faster “resource collapse.” Plan sandbox settings around that reality.

What’s the fastest way to know I set it right?

Do a deliberate stress run: have players spawn in different areas, drive, enter interiors, fight a horde, and loot at the same time. If it’s stable there, it’s stable in normal play.

Closing Thought (The Analogy You’ll Remember)

Think of your server like a crowded safehouse: it’s not the door that fails first—it’s the floorboards. Slots are the door; stability is the floor.
