Fatshark seems to be using steam datagram relay. This system forces players use relay servers so that traditional p2p connection won’t work anymore. Both client and host are forced to connect to a steam server to transfer data. Thus ping has become client-server ping + host-server ping, while it’s merely client-host in the old way. This is why players in the same house would have relatively high ping ---- @KunigundeH has to send data to a Frankfurt server then his brother receives data from Frankfurt. Russia players suffer a lot because the nearest server they could reach is deployed in Warsaw. This system also has no relay server in China mainland so that Chinese players have to connect Hongkong or Tokyo server.
As long as there’s no roll back or in-game alternative connection option, those who lags can only seek help from vpn.
So it’s actually not a bug or a problem causes lag. Instead, you’re lagging because fatshark’s “network rework” works perfectly. There’s little thing to do with your steam region or download region.
If you use windows resource monitor (like what @aweftg did) when connected with any player either being host or client. I highly suspect you would find most packages are sent to ips listed blow. These are the servers SDR system deployed around world:
