Normcore is lag even though I try it sample scenes with Pro License

I try to use Normcore to implement multiplayer for my app. I have purchased Pro license app ID to test best network performance. But although I only test with sample scene where we instantiate and sync prefab's transform, it start lagging when reach 7 players in the room. So where is the problem, our internet connection or Normcore?

Hi @Nguyễn Duy Hà. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- There could be several reasons why you're experiencing lag with 7 players in the room. Here are a few possibilities: 1. Bandwidth Usage: VR applications typically use more bandwidth than other types of games. According to the Normcore documentation (https://normcore.io/documentation/room/room-server-options#how-many-players-can-i-fit-in-a-single-room), VR applications can use 5-10 times more bandwidth than a typical FPS or racing game. If your application is using a lot of bandwidth, it could cause lag as more players join the room. 2. Server Configuration: The number of players that can fit in a single room can vary based on the server configuration. For VR titles, the default server configuration supports 8 players (with a burst up to 32). If you're using a different server configuration, it could affect the performance of your application. 3. Internet Connection: The quality of the internet connection can also affect the performance of your application. If the players have a poor internet connection, it could cause lag. 4. Physics Synchronization: If you're synchronizing physics objects, it could also cause lag. Unity's physics engine, PhysX, is non-deterministic, which means that it can produce different results on different devices. To keep the state of all clients in a room synchronized, Normcore needs to synchronize all objects between all clients all of the time. This can be resource-intensive and could cause lag. To troubleshoot the issue, you could start by checking the bandwidth usage of your application and the quality of the internet connection. If those are not the issues, you could look into the server configuration and the physics synchronization.

This API is implemented at ver 2.8, so before normcore is not supported for more than 8 people?

in vr with voice chat on public it was pretty limited you could split voice chat into another room but with this api it's not really necessary
