[HELP]Choke.

[ShuN^]

Sometimes while i'm playing i'm getting choke(about 15)and while my fps is 100 solid,it's being decreased on 15-20.It lasts 3 seconds and it fucks my game.Can someone tell me the settings that affect choke?

    * Causes of Choke (Inconsistency in settings)

      Frame-rate (Fps_max)

      Tic-rate (Cl_updaterate, cl_cmdrate)

      Bandwidth transfer speed (Rate)

      ISP data loss

 

Keep in mind that you cannot get more updates than whatever the server Tic-rate is set at.

 

If your settings are too high or too low (aren’t at the optimal value), you will get choke.

 

Using net_graph3

 

Valve still makes use of a command created by id-software back in the days of Quake, good ol’ “net_graph 3″. This command is important because it shows you a very detailed readout of all network activity to and from the game-server you’re playing on.

 

Un-optimized Net_graph 3 (on a 66 tic server)

 

Also

 

net_graph 3

 

Optimized Net_graph 3 (on a 100 tic server)

 

net_graph 3

 

You’ll notice in the above, “un-optimized” picture, that i have 13 choke, exactly the amount of data being lost due to a too low rate. You can use the right-hand values 57.4/s, 67.1/s to determine if you are communicating with the server optimally based on the server’s tic-rate.

 

Tips to reduce choke

 

The key to optimizing your settings are to match them with the server’s Tic-rate but add 1.

 

If you do not know of the Tic-rate of the server you are connected to you can type:

 

sv_maxupdaterate

 

    * So on a 100 Tic-server, your settings should be:

      cl_updaterate 101

      cl_cmdrate 101

      fps_max 101 (i use 121)

      rate 30000 (to determine max-rate for a given server, at the console type sv_maxrate)

 

Note: Do not allow your FPS to dip significantly below the server Tic-rate (fps_max 101 for 100 Tic server), or you will also receive choke.

 

Also, many servers will set your network settings automatically, quite often to less than optimal values! Make sure you check your network settings upon joining any server!

 

Things we cannot control

 

The more people connected to a server, the less resources the server will have to send data. Unfortunately this will vary depending on in-game activity. For example, If a server is running at 100 Tic-rate and has 32 players, it will need approximately 3,200 updates per second to maintain consistency with it’s clients. Obviously today anything much higher than this is simply not feasible without producing lag.

 

The largest smooth-game you can really get at the moment are 20 man servers at 100 Tic-Rate that are FPS-Boosted to 2000 server side fps (which is the max server fps available). Anything higher than that just demands too much on today’s hardware/bandwidth limitations and you will get choke.

 

Also, your Internet Service Provider may be causing Packet Loss (:”loss” above in net_graph 3). If that is the case it may be because of too many server hops. As i mentioned in another article, Gamerail offers a service to help resolve this problem if switching ISP’s is not an option.

Well,about the 'tic of the server',it has 18 slots.I don't know how much is it on tic  :D

I use these commands you told me but i still get 2-7 choke. :/

Hmm check rate,ex_interp

 

rate 25000

ex_interp 0.01

 

If those settings dont work also,i think is because from the server where you play.

Try to play in another server and tell me if is the same.

Also probably you have choke because your network broadband is to small.

I think it's my internet's problem cuz i used the commands you gave me and i was still getting choke about 25-30.

Anyway,thx for your help.

Lock it :)

Well but i see an improvement you said is 25-30

After mine settings you get betwen 2 and 7 so it's better.

 

me but i still get 2-7 choke. :/

 

Anyway change your network and i dont think you will have anymore problems.

Or check you pc mby is smthing wrong with him.

Locked.
