How to boost your connection?
As with every multiplayer game, a good and smooth gameplay all depends on your Ping. If you experience a high Ping or Lags first try to close down as much other programs as possible (such as; p2p download programs, msn, antivirus software etc.) to ensure that the problem isn’t in one of those programs.
If that doesn’t work there are a few commands you can configure inside ET to help you tweak your connection and lower your Ping.
The bigger X is, the more information your computer sends to the server, so basically your actions will be more accurate and gives you a smoother playing experience. 30 is standard but you will see that most ‘pro-players’ use 100 maxpackets.
Slow connection: /cl_maxpackets 30
Fast connection: /cl_maxpackets 100
Determines how many times the server sends your pc updates of the game state. 20 is standard but people with a fast connection could set this to 40.
Slow connection: /snaps 20
Fast connection: /snaps 40
The faster your connection is, the higher you could set your rate. 25000 is standard, use 5000 for slow connections.
Slow connection: /rate 5000
Fast connection: /rate 25000
Where X is a number, changes your packetdup setting to that number. Try 0 for a LAN, 1 for broadband, and 1 for modems.
