When my friend connects to my game, the delay often increases sharply after one minute, then times out for more than ten seconds, and packet loss is very serious. However, the VPN does not switch to relay mode, but remains directly connected until my friend disconnects. .
Hello,
Check if there is no programs that overload your network, like FTP, torrents or Windows updates.
And the more Radmin VPN networks you are connected to, the less performance you have.
Try to change metric of Radmin VPN adapter. Firstly, set it to 1. If it didn`t help, set it to 1500 or to the max value (you can read more here https://www.raymond.cc/blog/choosing-which-connection-to-use-with-windows-routing-table-editor-gui/) or (https://www.windowscentral.com/how-change-priority-order-network-adapters-windows-10)
If after restarting system, metric do not change.
Open regedit as administrator.
Create a DWORD (32-bit) Registry entry called "AdjustMetric" in "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Famatech\RadminVPN\1.0", and set its value to 0
