P2P vs Dedicated Game Servers: Which Should You Use?

For most online games, dedicated servers are the better choice for competitive play, while peer-to-peer (P2P) can work for small, casual groups. Your decision depends on the number of players, your budget, and how much you value fairness and stability. This article explains the differences, pros and cons, and how to pick the right hosting model for your game or community.

What Are P2P and Dedicated Servers?

In a peer-to-peer (P2P) setup, one player’s device acts as the host, and all other players connect directly to that player. The host’s internet connection and hardware determine the game’s performance. In a dedicated server model, the game runs on a remote machine that is not a player’s device, and all players connect to that machine. The server is typically owned or rented by the game developer or a hosting company.

How Each Model Works

P2P hosting: The host player runs the game simulation and relays data to others. If the host’s connection drops, the game may freeze or migrate to another player. Some games use a hybrid model where a central server handles matchmaking but the actual gameplay is P2P.

Dedicated server: A server program runs on a machine that is always on, often in a data center with high bandwidth. Players connect to it via the internet. The server can be rented from providers like AWS, Google Cloud, or specialized game hosting companies. Developers can also run their own hardware.

Performance and Latency

Dedicated servers usually provide lower and more consistent latency because they are located in data centers with optimized network routes. P2P latency depends on the host’s location and connection. If the host is far from other players, they may experience high ping. Also, the host player often gets a slight advantage because they have zero latency to the game state. This is a common complaint in fighting games like Super Smash Bros. Ultimate and Call of Duty when using P2P.

Costs and Scalability

Running dedicated servers costs money—either for hardware, electricity, and maintenance, or for renting from a provider. For a small indie game, this can be a significant expense. P2P is essentially free because it uses players’ hardware. However, dedicated servers scale better: you can spin up more instances to handle more players, whereas P2P is limited by the host’s connection and CPU.

If you are a developer, consider these cost factors:

Server rental: Monthly fees per server instance.
Bandwidth: Data transfer costs, especially for large player counts.
Development time: Writing server logic vs. implementing P2P networking.
Maintenance: Updates, security patches, and monitoring.

Common Problems and Misconceptions

P2P issues: Host migration can break the game mid-match. Cheating is easier because the host has control over the game state. Also, players with strict NAT types may fail to connect to each other.

Dedicated server issues: They require ongoing maintenance and can suffer from outages. If the server is in a different region, players far away may have high ping. A common misconception is that dedicated servers are always lag-free—they are not, but they are more predictable.

How to Choose

Ask yourself these questions:

How many players? For 2-8 players, P2P may be fine. For 16+ players, dedicated is usually necessary.
Is the game competitive? If rank matters, dedicated servers provide a fairer experience.
What is your budget? If you have no money for servers, P2P is the only option.
Do you need persistent worlds? Dedicated servers can run 24/7, while P2P ends when the host leaves.
What is your technical skill? Setting up a dedicated server can be complex, but many providers offer one-click installs.

Alternatives and Hybrid Approaches

Some games use a hybrid: matchmaking and anti-cheat on dedicated servers, but gameplay on P2P. Others use a “listen server� which is a P2P host with some server-side authority. For small groups, a listen server (a player-hosted game) is often sufficient. For large-scale multiplayer, dedicated servers are the industry standard.

Frequently Asked Questions

Can I run a dedicated server on my own PC? Yes, many games allow you to host a dedicated server on your own machine, but your internet upload speed and CPU will limit the number of players. For a few friends, it works fine.

Why do some games still use P2P? Cost is the main reason. P2P eliminates server costs and can be easier to implement for small player counts. Some games like Rocket League use P2P for casual matches but dedicated servers for ranked.

Does P2P always give the host an advantage? Not always, but the host has zero latency to the game state, which can be an advantage in fast-paced games. Many games compensate by adding artificial lag to the host.

What is the best hosting provider? It depends on your game and region. Popular providers include AWS, Google Cloud, and specialized game hosts like Nitrado or GPortal. Compare pricing and locations before choosing.

How much bandwidth do I need for a dedicated server? A rough estimate is 10-20 kbps per player for a typical shooter. For 100 players, that’s 1-2 Mbps upstream. But this varies widely by game.

Can I switch from P2P to dedicated servers later? Yes, but it requires changing your game’s networking code. It is easier to design for dedicated servers from the start.
