hey guys some of these console commands can help reduce your ping,
Rates control your latency (ping). Latency is the time it takes for information to come from your computer, to the server and back. Your latency goes up when you lag. You are wanting to have it as low as you can.
If you are on a low or capped speed you are going to want something like:
rate 6000
cl_updaterate 15
cl_cmdrate 15
If you are on a standard broadband connection
rate 15000
cl_updaterate 60
cl_cmdrate 60
If you are on a faster broadband connection
rate 25000
cl_updaterate 101
cl_cmdrate 101
Another thing you are wanting to set is the ex_interp .1
These rates might not work for everyone so sorry.
