It reduces the ping when playing in other regions. You can check by pinging a game server in another country without using the VPN and repeat the ping test by using ExpressVPN.
Now if you are playing on a game server that's hosted outside your region, Express VPN reduces network congestion and provides shorter connection route between you and gaming server. For instance if you are playing a game hosted in an Asian server and you are from Japan, but the game server is in China, choosing China in VPN will help reduce latency and lag .
