When I play on EU and US servers with my mate my 60mb connection gets throttled to 3.6 to 1.8 and I get a lot of connection lag in game to the point it is unplayable.
I never saw anyone post to this. It doesn't sound like a common problem though. Last few weeks I been playing on 1mbps connection, it tends to bottleneck but not throttle. I might consider support@uberent.com email, if nobody has any advice here.
Thats happening all tthe time, the server limit the maximum bandwith at a rather low level currently. Needs to be improved and will be improved in the future.
