We have official support only XBox 360 gamepads. All the rest - if the player can customize it. You can use the JoyToKey program to customize any joystick, or another program more convenient/understandable to you.
A ping is the time it takes for a request sent to a server to reach the server and back again. It is measured in milliseconds (ms): the slower the Internet connection, the higher the ping.
A high ping means that it takes some time for the request to reach the server. This is usually due to a slow Internet connection.
A low ping means that the user's request comes quickly, this means that the user can contact the game server quickly.
A good ping for a game is up to 50 ms, a normal ping is up to 100/150 ms. And a ping over 300/350 ms is the maximum possible threshold in the game. At pings above 300/350ms, players may encounter hangs, intermittent movements, and game crashes with the error "loss of internet connection".
This system was added for players not to quit battle intentionally (for example, for saving statistics if the battle goes to defeat) setting teammates up. Unfortunately, on the current moment of game development we are not planning to change this system.
