How much RAM does a
Windrose server need?
Short answer, honestly: 12 GB ≈ a duo, 16 GB ≈ a small crew of 3–4, 24 GB ≈ a big crew. That's lower than the dev's spec sheet on purpose — Windrose is a heavy UE5 game, and we measured roughly 4.6 GB resident with a single player on our own box, climbing from there as the world grows.
Quick reference.
The developer's guidance, what we actually measured, and the plan that fits.
| Crew size | Dev guidance | Measured on our hardware | AcidNodes plan |
|---|---|---|---|
| Duo (1–2) | ~8 GB | ~4.6 GB at one player, grows with play | 12 GB — $34/mo |
| Small crew (3–4) | 12 GB | climbs fast as the world fills in | 16 GB — $44/mo |
| Big crew (5–8) | 16 GB | best-effort — brand-new heavy game | 24 GB Extreme — $60/mo |
Our numbers sit below the dev's on purpose — we go by what we measured, not the spec sheet, and the first player alone loads ~4.6 GB. We don't sell an 8 GB Windrose tier (it only honestly holds ~2 players), and we won't promise a full 10 on a brand-new game we're still watching patch by patch.
Why the gap between "minimum" and "comfortable."
Four things push a Windrose server's memory up over a session:
Procedural world
The map streams in as your crew explores. More territory loaded = more RAM held — and it doesn't all come back.
Builds & ships
Every structure and vessel is state the server simulates. A sprawling base with a fleet costs more than a fresh start.
Boss & combat events
Naval fights and boss encounters spike memory and CPU in bursts — the moments you least want a stutter.
Long sessions & saves
Memory creeps up the longer a world stays live, and periodic saves add transient spikes. Headroom absorbs both.
Newer games cost more to host — and we'll tell you why.
A UE5 survival game like Windrose simply eats more RAM than a ten-year-old title — that's true at every host. The difference is we show you the measured footprint instead of quietly charging more and selling you "slots." That's also why we start Windrose at 12 GB while a lighter game like Valheim starts at 4: heavier game, fewer servers per box, priced to match. Transparent, not a gouge.

Windrose server RAM — straight answers
How much RAM does a 4-player Windrose server need?
Realistically 16 GB — and a heavily-built or widely-explored 4-player world can want the 24 GB Extreme tier. The developer lists 12 GB for four, but we measured ~4.6 GB for the FIRST player alone, so 12 GB is honestly a duo box. We'd rather size you up than watch your world rubber-band.
What's the minimum RAM for a Windrose dedicated server?
The developer lists ~8 GB for two players. We measured about 4.6 GB resident with a single player on our own hardware — but that's the floor of a fresh world, and it climbs as you explore and build, so 8 GB is a tight duo number, not a crew number.
How much RAM to run the Windrose server and game on the same PC?
Budget around 24 GB total — roughly 16 GB for the game client plus 8 GB+ for the server process. Hosting the server on a separate box (or with us) avoids splitting your RAM at all.
Does Windrose server RAM usage grow over time?
Yes. Windrose generates its world procedurally, so memory climbs as your crew explores new regions, builds bases, and triggers boss events — plus periodic save operations. The longer a world lives, the more headroom it wants. That's why we size above the bare minimum.
Can I upgrade my Windrose server's RAM later?
Yes — start at the tier that fits your crew and move up from the panel if your world outgrows it. No need to over-buy "just in case."
Why don't you price by player slots like other hosts?
Because "slots" hide the only number that decides whether your world rubber-bands: RAM. A host selling "8 slots" on 4 GB is overselling a heavy game. We price by guaranteed RAM and tell you the player-equivalent — so you know exactly what you're paying for.
