How do I tweak
my connection?
The commands shown below can be entered
in the console or added to your autoexec.cfg.
fps_max
While this setting will no longer improve
your connection it does help stop the confusion
between connection lag and graphics related
lag when, for example, jumping from 85 FPS
to 23 FPS. Set this by monitoring your FPS
while playing using net_graph 3 or cl_showFPS
"1", then set fps_max to your
average steady FPS
rate
This controls network packets so that your
connection bandwidth does not get saturated,
setting is for maximum bytes per second.
Note that with 1.1.04 or above and a Stac/Microsoft
compressed connection you can no longer
use higher rates than normal for your connection
type, connection tweak tables have been
adjusted to reflect that. See net_graph
for a guide on how to adjust this setting
or try the suggested settings that appear
at the foot of this page.
cl_cmdrate
In HalfLife patches prior to 1.1.0.0 your
FPS governed how many gameworld updates
you sent to the server, this is no longer
the case in 1.1.0.0 and above. Similar to
cl_maxpackets in Quake3 this setting restricts
the number of packets being sent to the
server by your client and can be used to
help connection bandwidth related problems
for those with low upload bandwidth. Note
that 56K modems, while downloading at up
to 56000 BPS, only upload at 33600 BPS or
less. You may wish to experiment with a
higher or lower setting based on your connection
type, for example 40 or higher for a digital
connection.
cl_updaterate
Similar to snaps setting in Quake3, the
cl_updaterate setting is used to calculate
how many gameworld updates you receive from
the server. See net_graph for a guide on
how to adjust this setting.
Suggested settings are in the table
that follows. They are however guidelines,
adjust them as needed by monitoring your
connection using net_graph and alter settings
based on its information. See the description
of how to use and interpret the information
that net_graph shows in the above table.
It is very important that you read the net_graph,
rate, cl_cmdrate and cl_updaterate notes
before you use these settings. If you do
not see an exact connection speed setting
then use the closest. Example, perhaps you
connect at 53000 or 52000 on modem, use
the 50000 setting from the table.

How
do I read the net_graph?
This is the net_graph, set to mode 1 (By
typing net_graph 1 in console)
|
1
|
FPS
Counter - Your current frame rate |
|
2
|
Network
Latency - This is your current network
latency. Unlike the Ping display on
the game scoreboard, this readout does
not count rendering & timing latencies
into the number |
|
3
|
Your
downstream bandwidth use |
|
4
|
Your
upstream bandwidth use |
|
5
|
This
is an animated graph displaying your
ever-changing ping. The higher your
ping, the
thicker this graph gets. This also displays
your lost packets in red. |
|
6
|
Your
current server update (incoming) rate. |
|
7
|
Your
current client update (outgoing) rate. |
You can change the netgraph's position with
the CVAR net_graphpos. Setting net_graphpos
to 1, 2, or 3 will place the netgraph in
the bottom right, center, or left section
of the screen
respectively.
Example, type in console: net_graphpos
1
To
change the width of the netgraph, use the
CVAR net_graphwidth, which defaults to 192.
Example, type in console: net_graphwidth
250
You
can change the graph's default height of
64 pixels by the CVAR net_graphheight.
Example, type in console: net_graphheight
100
