VEIN Server Requirements and Sizing
The public VEIN dedicated-server reference gives a useful starting point: a 64-bit system, Windows as the tested path, and at least 8 GB of memory to start. That is a baseline, not a universal player-cap guarantee. Early Access builds, explored world state, zombie activity, saves, and other services can change the real requirement.
Start here
- Use the current dedicated-server package and branch.
- Start with the reference 8 GB memory guidance, then measure peak use.
- Prefer fast SSD storage and a modern CPU with headroom.
- Test the largest expected group on the actual world.
What drives resource use?
| Factor | What to observe |
|---|---|
| Players | CPU, memory, network traffic, and whether delay is shared by every player. |
| World age | Save size, restart duration, disk use, and behavior away from the starting area. |
| Zombies and activity | CPU during busy scenes and whether the current build exposes a relevant control. |
| Backups and updates | Disk latency, free space, and whether scheduled work overlaps with play. |
| Mods or custom content | Load time, memory, support status, and whether every client has the same package. |
CPU, memory, and storage choices
- CPU: prioritize a modern, consistently available core rather than a vague “gaming CPU” label.
- Memory: leave room for the OS, logs, backups, and other server processes beyond the 8 GB starting guidance.
- Disk: SSD/NVMe helps startup, saves, and backups; it does not cure a simulation bottleneck.
- Network: stable UDP reachability matters more than a headline bandwidth number for a small group.
- Isolation: avoid heavy unrelated jobs during peak play and save windows.
Measure before upgrading
- Record branch, build, world, player count, and server process.
- Measure a quiet session and then the busiest expected activity.
- Record CPU, memory, disk latency, warnings, save duration, and disconnects.
- Compare with a fresh test world on the same machine.
- Change one resource or setting and repeat.
Ports and reachability
The dedicated-server reference lists UDP 7777 for game traffic and UDP 7778 for query traffic, with optional TCP 7777 for RCON. Confirm the current package and provider mapping before opening anything; a listed server is not proof that the game port works.
