Well that didnt happen last night but I swear I shot Solitude point blank a few times and some how I ended up dead,And MH looked like he was teleporting lol.
Seems a shame thou I have extra bandwidth to play games but not enough to get TV series.
While you weren't getting a "No response from host" message, that is in reality exactly what was happening, this is made pretty clear by the "teleporting". Server sends a packet to you telling MH has moved, it gets lost, server retries sending a few times, finally it arrives on your side intact. By then, he has actually moved quite a bit, so your client catches up by "teleporting" him to the new location.
At 200ms, on a fixed line, you would actually be able to play (although at a disadvantage) because of lag compensation, but with the packet loss from wireless, a FPS is just hopeless.
This is not a "OMG internets in South Africa is so rubbish!" thing though. This is a wireless thing. Wireless in SA is about as good as international offerings (not in terms of pricing), but with international fixed lines being so cheap and fast to set up (and just fast in general), you can get one set up every time you go to a coffee shop and whip out your laptop

Wireless isn't very popular overseas because of all the problems with it.
And yes, 500ms+- is going to put you at a hefty disadvantage in PvP in an MMORPG. He who's packets arrive first wins, lag compensation or not.
