Every week we get a support ticket that starts the same way: "which GPU tier do I need for my Unity server?" The answer, almost always, is none. If you're evaluating unity dedicated server hosting vps options for a multiplayer build, the GPU question is the first misconception worth clearing up — because it changes which plan you actually need and how much you pay for it.
The GPU Misconception, Cleared Up
A GPU matters when you're building the game — baking lightmaps, running the Unity Editor, testing shaders, or compiling a Roblox Studio scene. None of that happens on the box that runs your live dedicated server. A headless Unity server build (or a Roblox server executable) is a CPU and memory workload: it runs game logic, physics ticks, and netcode message handling, and it pushes small UDP packets to connected clients. There's no rendering pipeline to feed, so there's no frame buffer to fill and no GPU to feed it.
This is why a standard VPS — not a GPU instance — is the correct target for a live Unity or Roblox-adjacent server. Reserve GPU spend for your workstation or a build machine; put your budget into vCPU, RAM, and network headroom for the box that stays online 24/7.
Root Access: What You Actually Control
Every VPS tier at noded.cloud ships with root SSH access, which is the part that actually matters for a custom server build. Root access means you're not working around a managed panel's assumptions about which engine you're running — you can:
- Install the exact Linux runtime dependencies your Unity Linux dedicated server build expects (or a Roblox-adjacent server toolchain, if you're running self-hosted tooling)
- Configure systemd to keep the server process alive and auto-restart on crash
- Set your own firewall rules (iptables/nftables/ufw) instead of fighting a preset one
- Run multiple server instances or shard sizes side by side without a control panel forcing one game per node
Every tier includes IPv4 and IPv6, so you're not stuck behind a single legacy address if your matchmaking or client discovery expects both.
Configuring UDP Port Ranges for Unity Netcode
This is the step that trips people up most on locked-down hosts: Unity's netcode stacks (Netcode for GameObjects, Mirror, or a custom transport) typically bind a UDP port per server instance, and some setups open a range across several instances or regions. On a VPS with root access, configuring unity netcode dedicated server udp ports is a firewall rule, not a support ticket:
- Pick your UDP port or range — 7777 is the common single-port default for Unity Transport and Mirror, but multi-instance setups often open a small range instead
- Open it in your firewall —
ufw allow 7777/udpfor a single port, orufw allow 7770:7784/udpfor a range, or the nftables equivalent - Bind your server process to the same port or range in your netcode transport config
- Confirm the port is reachable from outside with a UDP probe before pointing clients at it
Because you own the box end to end, there's no shared-hosting layer silently dropping traffic on ports outside a pre-approved list — a common wall people hit on panel-only game hosts. The same root-level control applies if you're running self-managed Roblox-adjacent tooling: you decide the port map, not a template.
Roblox on a VPS: What's Different
Roblox's official experiences — including private and VIP servers — run exclusively through Roblox's own cloud; they can't be self-hosted on a VPS or any other third-party infrastructure. What a VPS is commonly used for is the tooling around an experience: teams host a roblox dedicated server on vps in the sense of proxy/relay layers, bots, or companion backend services (leaderboards, data stores, webhooks) that sit next to a Roblox experience. For that workload, the same fundamentals apply: no GPU needed, root access to install your stack, and open UDP/TCP ports as your tooling requires. If your project is closer to a full custom multiplayer game inspired by Roblox-style building mechanics rather than the Roblox platform itself, the Unity guidance above is the direct path.
Picking Unity Dedicated Server Hosting VPS Plans by Tier
Unity dedicated servers scale with simulated entities and tick rate more than with player count alone. As a starting reference, here's what we run under our own tiers:
| Tier | vCPU / RAM / NVMe | Price | Good fit for |
|---|---|---|---|
| VPS I | 1 vCPU / 2GB / 40GB | €4/mo (€0.0056/hr) | Small test builds, low player counts |
| VPS II | 2 vCPU / 4GB / 80GB | €6/mo | Small-to-mid sessions, single instance |
| VPS III | 2 vCPU / 8GB / 120GB | €10/mo | Multiple concurrent server instances |
| VPS IV | 2 vCPU / 8GB / 120GB | €16/mo | Higher-priority CPU allocation for busier sims |
| VPS V | 4 vCPU / 16GB / 200GB | €30/mo | Larger sims, several shards |
| VPS VI | 6 vCPU / 32GB / 400GB | €58/mo | Heaviest tick rates, many parallel instances |
All six tiers run on NVMe storage with 1 Gbps unmetered symmetric bandwidth, billed hourly to the second — so you can scale a tier up before a launch weekend and back down after without eating a monthly commitment either way. Full specs and ordering live on the VPS hosting page.
Network Path Matters for Netcode
Netcode is latency-sensitive in a way a web app isn't — every UDP packet round trip is felt as input lag. Our VPS fleet sits on the same network as the rest of our infrastructure: 13 anycast POPs across the EU giving sub-5ms intra-EU latency, which keeps the client-to-server hop short if your player base is mostly European. If you already run — or are considering — managed game servers for titles like Minecraft, CS2, or Rust alongside your custom Unity build, our game hosting platform runs on the same low-latency network, so you can split workloads (managed titles on game hosting, custom Unity build on VPS) without changing network characteristics.
If your project eventually outgrows a VPS — persistent worlds with heavy CPU load, or a need for guaranteed physical cores — our dedicated servers are the next step up, with the same root-level control you'd already be used to.
How Noded Can Help
We run our own network end to end, so when a UDP port doesn't answer or a firewall rule doesn't behave as expected, we're debugging our own stack — not relaying a ticket to an upstream provider. Every VPS tier ships with root SSH, so nothing about your Unity or Roblox-adjacent server setup is gated behind a panel we didn't build for game workloads. If you're not sure which tier fits your player count and tick rate, spin up the smallest one, load-test it, and resize — hourly billing means that costs you cents, not a wasted month. Our VPS hosting plans are the starting point for exactly this kind of build.
FAQ
Do I need a GPU to host a Unity or Roblox dedicated server?
No. A live dedicated server runs game logic and netcode, not rendering — there's no frame buffer to fill. GPUs matter for the Editor, Studio, and build work, not for the server process itself. A standard VPS with enough vCPU and RAM is the correct fit.
What UDP ports does Unity Netcode need open on a VPS?
It depends on your transport (Netcode for GameObjects, Mirror, or a custom one), but most single-instance setups use 7777, while multi-instance setups often open a small range instead. With root access, you open that port or range in your firewall (e.g. ufw allow 7777/udp) and bind your server process to match — no support ticket required.
Can I host a Roblox dedicated server on a VPS?
Roblox's official experiences, including private and VIP servers, run exclusively through Roblox's own cloud — they can't be self-hosted on a VPS. What a VPS is commonly used for is adjacent tooling: bots, relays, and backend services (leaderboards, data stores, webhooks) that sit alongside a Roblox experience. Root access lets you install and configure exactly what that tooling needs.
How much RAM do I need for a Unity dedicated server?
It scales with simulated entities and tick rate more than raw player count. Small test builds run fine on 2GB, while busier simulations with multiple instances benefit from 8GB or more. Starting on a smaller tier and resizing after a load test is the cheapest way to find the right fit.
Does root access on a VPS actually matter for a custom game server?
Yes — it's the difference between installing the exact runtime your build needs versus working around a managed panel's assumptions. Root SSH lets you configure firewalls, process managers, and port bindings directly, which is exactly what custom Unity and Roblox-adjacent server setups require.
