What does BF 4 have to do with anything? Its up to each dedicated server to run its own mod tools. If you care to now , I play Bf 4 like 2 hours daily without much problems.
some servers allow players from anywhere in the world, (Bad, usually laggy with more oversea players)
some servers auto kick players above 100ms ping (Better )
some servers enforce regional + max ping + active admins + they indicate if its NA east or west coast (Best)
As for DAMP, buy a mic ask others if they are lagging as well, if every agrees than just vote kick the host out of the game. DAMP should have a Tool that test your upload bandwidth , if you don't meet the min , it should not allow you to host public games.
Hosting a game is all about upload speed. Something maybe not everyone is aware but usually internet provider caps the upload speed but offer great download speed. If that is the case than hosting is not for you.
Same engine, some of the same issues even though this is p2p. If you didn't play BF4 from the beginning then you have no idea how bad it was. My point was that none of the lessons learned about the engine were likley taken forward into DAI, as there are similar problems.
I also brought up BF4 as even tho it's server based, there ARE serious issues with players joining from out of reigion (no region lock), or with poor connections. The community called for region locks and ping stats for players to be posted/considered in joining a server (or host in this case).
So few players on dailup bother to use a mic it seems... asking isn't really practical. What would be practical, is a menu system where by you could stipulate the max latency acceptible for selecting a lobby host.
Y'know what, yer right, not relevent at all, just go back to whatever it was you were doing....
