I'd really love to see a "VPN for Gaming Guide" or something like that, as many people use them and other, similar-sounding services to reduce lag or latency when playing online games.
How would that even be possible? Wouldn't the VPN introduce even more latency in the speed?
I'd love an answer to these questions - the added latency presumption is logical, but, what if it meant that your overall UP-TIME was 300% better? Latency is such an issue in South Africa because all the cool games are always hosted very far from us. Part of the issue is that we have failed connections from time to time and packet loss (obviously). If a VPN solution adds less than 30ms to my already high latency (230-odd ms average for League of Legends for example) then I'd prefer to go with a VPN solution because sometimes the packet loss makes my mood less than desirable.
It depends. The theoretical maximum speed a signal can travel is just under 300km/ms , so there is a hard minumum when it comes to latency between you and a server. Then there's computer cycles going to the network card, there's the input deay from your keyboard and output from your monitor... all of these things have and cause small latencies. But if you're strictly talking about server latency, VPNs often can reduce it when there is something between you and the server causing a slowdown, i.e. a high traffic datacenter. Taking a different route to circumvent these places is something a vpn is capable of being set to do, and is where most latency increases would come from. Under ideal conditions, you are right, they would add latency rather than remove it, but the internet is rarely, if ever, ideal.
