Posted: Wed, 29th Jun 2005 16:15 Post subject: The (self-proclaimed) Official BF2 Optimizing thread!

Post usefull informations about optimizing and bug/problem fixing you have found here. Please stay concise and on-topic.

The EAX problem:

On many systems, disabling EAX in the sound option menu gave a remarkable increase in framerate. This is mostly due to bad implementation of the EAX and the aweful optimizing for cheaper, on-board sound cards.

The AC97 sound card issue(s):

Updating the AC97 with the latest realtek drivers can fix many issues with stuttering and general lag if you have an AC97 based sound card. (this includes a vast majority of on-board sound cards.)

The PunkBuster manual update:

In some cases, Punkbuster can slow down your system because it is unable to automatcly update itself. This usually happens on system with tight firewalls (all computers should run an aggressive firewall, in my opinion.)
Follow these instructions:

The firewall ports issue:

In many cases, firewalls can be a double sided blade. Opening these ports should allow Battlefield 2 to run properly

This should help reduce the amound of servers that ping with 0 latency.

Plenty of useful tips posted here by Nerrd

Code:

---------------------------------------------------
trick for play with 64 Gamers in Singleplayer
---------------------------------------------------
search: BF2/mods/bf2/ai than open aidefault.ai with Wordpad

read the instructions and change:

rem aiSettings.overrideMenuSettings 1
rem aiSettings.setMaxNBots 32
rem aiSettings.maxBotsIncludeHumans 0
rem aiSettings.setBotSkill 1.0

delete the rem before the aiSettings... and change 32, in 48, 64 so you want

so now start game and you can play with more bots...

*works in single player and lan games, will work online *IF* the server hosting *AND* all the clients have the same hacked python file.

navigate to:
C:\Program Files\EA GAMES\Battlefield 2\python\bf2\stats

Open the file unlocks.py with notepad

find the line:
Code:

defaultUnlocks = [0, 0, 0, 0, 0, 0, 0]

change to:
Code:

defaultUnlocks = [1, 1, 1, 1, 1, 1, 1]

--------------
open up the file gpm_cq.py with notepad, it's under Battlefield 2 Standalone Demo Server\mods\bf2\python\game\gamemodes
then locate:
host.registerHandler('TimeLimitReached', onTimeLimitReached, 1)
and replace by:
#host.registerHandler('TimeLimitReached', onTimeLimitReached, 1)
that is in the line 32 Very Happy

-----------------
Command Line
-----------------

There are a range of commands - mainly designed for servers running BF2 - which can be activated via the BF2 command line. You can use these commands by going to the 'Battlefield 2 Demo' shortcut you use to launch the game, right-click on it and select Properties. Then in the Target box, after the "C:\Program Files\EA Games\Battlefield 2 Demo\BF2.exe" +menu 1 +fullscreen 1 text, insert another space, then use any of the commands below. Each command must have a single space between it and the next command.

For example, one of the most commonly requested commands is to run BF2 in 1280x1024 resolution (or another custom resolution) - particularly for LCD displays which display the best image at their native resolution. To do this, change your command line to look like this:

"C:\Program Files\EA Games\Battlefield 2 Demo\BF2.exe" +menu 1 +fullscreen 1 +szx 1280 +szy 1024

Note the addition of the +szx and +szy commands which respectively set the width and height of the resolution to be used. Substitute other values for other resolutions (e.g. +szx 1900 +szy 1200).

The following are the known command line commands for BF2, and descriptions where possible:

+dedicated - Start in dedicated server mode

+multi - Allow starting multiple BF2 instances

+joinserver - Join a server by IP address or hostname

+playername - Set the player name

Config Files
-------------
Battlefield 2 has a large number of config (.con) files spread throughout its directories. These can be edited using a text editor like Windows Notepad or Wordpad. Before editing any .con file, first make sure you have a backup copy of it.

However as you may have noticed, editing some of the .con files can prove pointless as the changes seem to have no impact. I have found that the main configuration files which do have an impact are found under your \Documents and Settings\[username]\My Documents\Battlefield 2 Demo\Profiles\ directory, with the settings for each profile listed under a numbered directory (e.g. \0001 for the first profile, etc.). You should stick to editing the files for your specific profile, as messing with those under the \Default directory will affect all profiles. To see which particular profile is currently in use, open the Global.con file under the \Profiles parent directory first, then see which number it mentions, and go to that particular numbered directory to find the files mentioned below.

For the moment I've found few useful tweaks to these files, as most of their settings can be altered using the in-game options, or the tweaks have no impact. However here are a couple of things to note:

Video.con

This file contains the graphics-related settings. Note however that if you try to alter your resolution here for example, it will typically lead to BF2 not starting up, or crashing after the login screen, or simply not applying the desired resolution. Use the Command Line method further below to set a custom resolution.

Controls.con

To change particular keys which are automatically bound to certain functions in the game (and can't be changed in the in-game settings), find the line for that particular key (e.g. IDFKeyboard IDKey_LeftCtrl is the line which contains the Left Control key mapping), and delete that line. It should now be free to be mapped in the Controls section of the in-game settings.

Sadly the above is all I know about the config files at the moment, more will follow as I experiment and get reader feedback.

Console Commands

To open the BF2 in-game console, press the '~' key (or the key above TAB) to open/close the console. To see the list of command categories, press the TAB key twice. To see particular sub-types, enter the start of the command press TAB twice. E.g. enter renderer, then press TAB twice to see the renderer sub-class of commands.

The list below is the full list of console commands, however many commands don't have descriptions. Please Email Me if you are absolutely certain what a particular command does through your own personal testing. This will help me finish this list as soon as possible for all to share.

Admin Commands

These commands are used by server administrators.

admin.listPlayers - Lists the players connected to the server, showing their name, ID number and IP number.

admin.runNextLevel - Forces the server to end the round and start the next map in the map list.

admin.currentLevel - Shows the map list ID number for the current map being played.

admin.nextLevel - Shows the map list ID number for the next map to be played.

admin.restartMap - Restarts the current map.

admin.banPlayer [player ID number] [timeout] - Enter the player ID number you want to ban. Bans the player from the server by using their IP address. The timeout value controls the length of the ban e.g. perm for permanent ban, round to ban them for the rest of the round, and 180 is 180 seconds (3 minutes).

admin.banPlayerKey [player ID number] [timeout] - Enter the player ID you want to ban. Bans the player from the server by using their CD key hash.

Remote Console

These commands are used by server administrators.

To setup remote console access to the server, onthe server create a new plain text document in \admin\ called default.cfg and enter the following text into the new file:

port=4711

password=YourPassword

Save the file, and start the server. Now you can access the server remotely by using the following commands from a client:

rcon login [YourPassword] - Use this command to login to the server.

rcon users - This command lists all the users connected to the server. Very similar to admin.listPlayers

rcon exec [command name] - Replace with a console command you would like to execute on the server. For example: rcon exec admin.kickPlayer 3

Exit - Quits the game to desktop.

Please submit any other fixe/tweak that have helped you or you just came across. BF2 is an addicting and fun game, but it runs like serious shit. Beta testing just isn't what it used to be.

If you feel you deserve credit for any tip/tweak/fix posted here, please PM meor post here and I will add you, I'm way too lazy to dig through Nforce to spot the original poster of all of these.
