It's written than there are 2500 people playing multiplayer, but when I look at the servers list, they're barely filled

Hello, only the official servers are somewhat filled such as 8 out of 10 people, but why can’t we just play 20 or 30 people? But that’s not even the case, my question is where can I find servers with populated servers such as 20 players playing and USA, so there’s no ping problems and people speak in English.

The reason we do not have 10+ Servers on the official ones is because the average users cannot run more than that without getting 0.1FPS.

In order for users to play a server does not have to be in the serverlist.
There are also many many other servers which are not official.
