A frequently asked question about Unity’s Netcode is:

How many players does Netcode for GameObjects support?

Interestingly, this closely related question is never asked:

How many frames per second does Unity support?

---

The answer to both is quite simply:

=> As many as your game is designed to handle.

---

Of course there are reasonable upper bounds.

The frames per second are ultimately limited by the monitor’s refresh rate, vsync or not.

The number of concurrent players in a multiplayer game is primarily limited by your expertise in realtime networking and design + implementation of multiplayer game architecture.

Furthermore, the financial success of a multiplayer game depends on limiting the running costs of the integrated game services, which again is dependent on your design and optimization skills.

I answered this question in greater detail on the Unity forum. It deserved to be answered once and for all with a resounding:

It depends! 🙂

And it’s almost entirely on you! 😉
