But we can relatively estimate the pings with game servers with the pings test results of the servers from the same region.
That depends on the particular game servers. If they give preference to geographically closer gamers, then you won't get a decent ping without using some kind of VPN. Otherwise, it should be the same.
There is also the two other things which can be done:
- SSH tunneling...will probably not be free
- Changing the settings of your network. If someone desires it, I will post that fix here. It will significantly reduce pings but decrease the efficiency of your network and slightly increase your upload size.
