the information I gave is only useful in regards to gaming.
VPN has some other use case such as it literally being a 'virtual' Local Area Network(LAN). allowing functions such as public folder sharing in a local network that is normally only available in a 'physical' LAN setups. you can also play LAN games of the good old days due to this reason.
another feature would be anonymity by masking your real IP address behind a VPN so you won't be tracked by other more savvy online users.
I'm glad to have helped. 😊
