Hi all,
Since you managed to hex edit the COD2 binaries, is it possible for you to have a look at COD2 1.0 binaries? Maybe you can crack it so it will have the same download speed as 1.2 and 1.3.
Increase download speed COD2 1.0

24th February 2014, 11:02MitchAdding www download to 1.0 is not possible, because it also requires changes in the client.Quote:

rate = sv_maxRate->integer;

But is it possible? For example my server have this fixed binary and I have it. It's not a big deal if not all players have it. It will just save some time for people who have this fixed binary

24th February 2014, 12:17MitchI could try to increase the value of sv_maxRate. (like you can change sv_maxClients to 128)Quote:

Could you give it a try please? And how to change to maxclients 128?
-
24th February 2014, 12:24MitchYou change it by editing the hex 40 (64) to 80 (128) at offset 4BBAE (1.3).Quote:

This means that if your player numbers exceed what the game can handle in terms of memory and limits, it will crash the server even though there may be 1 or even no one online at the time. The engine will know it can't handle the full quota of players.Quote:

This is why if you have hit a limit, such as max script varibles, or server commands, reducing your player slots can sometimes help. Particularly with COD4, if you keep your player slots down to below 20, you can cram more into your mods. However, if you go over 22 players, a lot of mods around today for COD4 crash servers because of limits. The Openwarfare mod - one that I am actively involved with - is notorious for crashing out at anything above 26 players. Keeping the number down to below 22 or even 20 allows us to put more into the mod. -

Can you make SS of your HEX editor? Because Im very new and Im not sure if I do it correctly :/

Perhaps Mitch can write an LPatch file to be used with the ever-so easy to use LPatcher program? Then all you would have to do is run the LPatcher program, load-up the file and it will automatically update your executable.

I changed the first MAX_DOWNLOAD_BLKSIZE from 2048 to 36864. (gonna test now if it works on 4096)Quote:

Edit: a higher value doesn't improve your download speed. -
24th February 2014, 13:55Ni3lsCan you show how to do this with Hex Editor? Some SS would be very helpfull :)Quote:

The 40h says that the max value of sv_maxclients is 64.
Now switch to hex view and click on the 40. Now you will see the offset at the left bottom in IDA:

In your hex editor go to the offset and change the 40 into 80.

Moving on from sv_maxclients...
I'v noticed on some 1.0 servers the download speed is 20kbps (Highest I'v ever seen my server go is 12kbps).
Could anyone shed any light on how this was done?
I'm pretty sure its not lag-related because the server which gives me 20kbps has 350 ping yet local servers with 50 ping will only do 12kbps.
Downloading almost twice as fast can make a big difference. -

Never tried it, but I would play around with the network cvars of client/server like sv_maxRate and cl_maxPackets etc.
-
19th July 2014, 16:29filthy_freak_Yeah I'v fiddled with sv_maxRate & cl_maxPackets both client & server without noticing any difference (cl_maxPackets = 100 & sv_maxRate = 25000).Quote:

Keep in mind that the reason these rates are so low is because it could lagg your server / ingame players when some player is downloading a file.

What have you set in your client as connection under multiplayer options?
It should say LAN/Cable/DSL. This means that the dvar 'rate' is set to 25000 instead of 5000.
Information about how to calculate your required sv_maxRate: http://www.fpsadmin.com/forum/showthread.php?t=9016
Example: 1 * 25000 * 8 = 200000 = 200 kbps = 20 kilobytes/s -

In answer to your question: in your server config file, set this dvar:
Code:set sv_maxclients "32"

COD2 isn't build for having more than 64 players. Running a server with 65 or more players will be very laggy and buggy or will just crash. -

Hi, sry for the late post but i wasn't sure if its stable enough. I was able to push the download speed to 19 kb/s by reversing the entire download function and forcing some values in it. I tried everything but it seems like having the download above 19 kb/s is not possible.
It's in my libcod repo, there's been 4 commits so far related to this function:
https://github.com/voron00/libcod/co...234fd7f6c997d5
https://github.com/voron00/libcod/co...cb8f3baf5100b9
https://github.com/voron00/libcod/co...2ee8ea3f6fcedf
https://github.com/voron00/libcod/co...8f3d5bacd2b329
I've been running this for nearly 3 mouths and it seems fine. :) GL. -
19th April 2020, 21:52CaptainSlowIs there anything you need to do/set in the server config in order to get the 19 kb/s download speed when using your version?Quote:
