cg_rate

cg_rate is related to the connection bandwidth usage to the server.

Usage:
/seta cg_rate 25000

Values: 2500 to 25000

Note:
1000=~1KB/s.
56k modem users should set it between 3000-4000, broadband (ISDN) users to 25000
If you have low rate (around 4000) but you have ISDN internet connection you might have lag.

In extrem cases, if players using a setting below 2500, their movement will be very strange (possibly forces some warping) which makes them very hard to hit.
