System: if its naked dsl i didn't think you needed filters
You do need filters. Since you are putting data over a voice line you need to filter out the excess noise from the voice signal so it does not interfere with the data signal.
Naked DSL just means that they are putting their equipment in the exchange.
ATinyChipmunk: Ive found the faster your upload the better, i just moved from paraparaumu where i had cable, so 2mbit up gave me around 25-30ping, i was in a server last night, 400-1000 :S
That has a slight trouth. Yes a faster upload can do no harm but no you do not need it.
Ie. Lets say CSS uses 6KB/s up.
If no one else is using the upload you'll get that 6KB/s no problem so all the data will get through straight away.
If some one else is using the net they will most probibly be uploading at some level, the more they upload the less likely you are to have the 6KB/s you need. If other users or programs are cutting into that 6KB/s you need it will cause you to lagg because the game will have to catch up with the data it has not sent.
10KB/s should be fine for 1 user and maybe 2, just running the game. If you have more users or some one is downloading or torrenting this may cause you some issues.
