     Hi, and welcome to my BFV tweaking guide. The goal of this guide is to 
help people have the best expierience they can while playing BFV.I've found
that many people have quit this game already due to poor system performance.
A new patch isn't always a safe bet either. It can make things worse. So I've
come up with some things that can help run this game smoothly and lag free.
They might not work for everybody, but for the most part, if applied 
correctly, you'll be able to enjoy this game to the fullest.


***Straight from the box***


Windows 98/ME/2000/XP
933Mhz PIII or Athlon Processor
256 MB RAM
64mb DirectX9 video card
Directx9 Sound card
2gb hard drive space
16X CD Rom Drive
Cable, DSL or faster

My suggestions to run this game decently are as follows:

Windows XP
2 Ghz Processor
1 gig DDR RAM
128 MB Video Card

    They're pretty much the main players in perfomance, and the main things
you need to pay attention to.


***All settings are based on WINDOWS XP***

      Many factors contribute to slow down and lag. As the game stands 
right now, most of you are not having system problems, you're having
server lag problems. The net code for this game at the momentis horrible.
I get pings of 10 and it still lags. I know its not my computer, because 
I'm getting 80-90 FPS while its lagging. This is a server side issue, so 
make sure you know if you're lagging or slowing down. You can check your 
FPS(Frames Per Second), by opening the CONSOLE. This is achieved by 
pressing the TILDE KEY(~`). Its usually next to the 1 key. Once open, type 
in FPS 1. Hit enter, then the console key again. You should see your FPS 
in the upper left of the screen. To turn it off, repeat the steps above, 
but use FPS 0.

      Make sure you don't have a lot of programs running in the background.
The most I suggest to be running would be 15. You can check to see how
many you have running by opening up the TASK MANAGER. Press CTRL-ALT-DEL 
at the same time to bring this up. Don't just start shutting down things,
as they may be vital to your system stability. I suggest going to Black 
Viper's(www.blackviper.com) website. This guy has taken the time to go 
thru WIN XP and WIN 2000, to find out what you can safely turn off in the 
WINDOWS SERVICES. Follow his directions, and you'll see a huge improvement
 in performance.

      Don't try to play this game on a 56K. It slows down everything. Not 
just for you, but the whole server. I know some people can not get cable
or dsl in their town. Move to somewhere you can get it. Just kidding.

      If you can, I suggest getting a second hard drive, and running a 
dual-boot system. Install the bare  minimum on it. Make it your gaming 
system side. Its not very hard to do and it gets the most perfomance out
of your hardware. The OS isn't bogged down by extra, un-needed programs. 

Go to www.microsoft.com for tips on running a dual-boot system. Also, if
you can afford it get more RAM. That always helps performance. 

      Defragment! This is a very important thing to do. Files get spread 
all over your hard drive and in turn, degrade the performance of your
machine. Run the windows defragmenting program at least once a week or 
after you've installed or un-installed 2 or more programs.

      Spy-ware can cripple a system, too. I suggest you get Ad-aware and
Spy-bot. Both have free versions for download. They can remove all adware
and malware from your system. Google for them! 

      Make sure you have the latest drivers for all your hardware. They 
can really be a factor in performance sometimes. Drivers usually fix 
performance related issues. I highly recommend this step.

      Increasing VIRTUAL MEMORY, or the PAGEFILE size, can sometimes help
out systems with lower amounts of RAM. I've read numerous articles on the 
subject, and found that size really does matter. LOL! I suggest making the 
size 3 times the amount of RAM that you have installed. So, if you have
256MB of RAM in your system, make your PAGEFILE size 768MB. If you have
at least 1GB of RAM, I wouldn't even worry about this at all, since its
never really a factor. Let Windows manage this or have no PAGEFILE at all.
To access the PAGEFILE, go into the CONTROL PANEL and click on SYSTEM. 
Click CHANGE under VIRTUAL MEMORY. Select CUSTOM SIZE. Plug in the numbers
and click SET. I have another tweak for the PAGEFILE you can find under
the ADVANCED TWEAKS of this guide. 

help some slow moving systems, also.


*Make sure you have the latest patch for the game which is 1.2*

     If you're at or slightly above the system requiements, run the game
at low settings. Don't try to run it medium or high. Its going to suck
for you if you do. I run the game at medium and I have a fairly decent
video card. If you have a Radeon 9800 or a GeForce 5950, then you can run 
this game at high. Everyone's system is different, so try out 
different settings to see what your system can do.

     Its not worth it to run this game at 800X600. You miss out on so
many beautiful things. I wouldn't go any lower than 1024X768. You'll 
lose maybe 2 FPS. No big deal. Sometimes, it helps to run this game at 
a 60Hz refresh rate. I haven't tried it, but some people say it does 
wonders. Turn off AA(Antialiasing) and AF(Anisotropic Filtering) 
if you don't have a high end system. Especially if you have an ATI 
card. EA has stated this themselves.
     Sometimes it helps to run in 16 bit mode. Less colors, more 

     In the video settings uncheck shadows and lightmaps. 
You'll get a few more FPS without noticing any degredation in quailty.

     By pressing the F8 button in game, you can keep the radio commands
from displaying at the top of the screen. This can increase performance, also.
Especially on low end systems.


     I usually turn the menu music and map loading music off. This is 
especially important if you  do not have a lot of RAM. It seems to 
take up a lot of memory to produce the menu music and map loading 
screen music. It definetly helps perfomance to eliminate menu music.
Turn your sound settings to low or medium for a perfomance increase.
Use the least amount of channels that you're comfortable with. I know 
I need sound to play this game, so do some expirementing with sound 
channels. OCCLUSION is when a tree or an object blocks sound. You might
want to turn this off. I really don't hear any difference whether its 
on or off. But, I bet it takes up memory and cpu cycles. 
Get the latest drivers for your sound card.


***Use these settings at your own risk! I claim no responsibility for
any damage done to your system***

    First off, make back-ups of all the files we are about to go 
over. These are just some .con changes, I have found very useful. I
use them all myself. You can find these all by following this path:
by default C:\Program Files\EA GAMES\Battlefield Vietnam\Mods\

    This tweak is courtesy of GameFaqs user, APPLE PIE. I give him 
all the credit. Open up the DEFAULT.con file with NOTEPAD. By 
default it looks like this:

rem *** for BC
Game.GameLevelPath BFVietnam/Levels/Operation_Irving/
Game.useMenu 1
Game.useHud 1
Game.menuMain BattlefieldMenu
Game.menuInGame InGame
Game.menuMap Map
Game.DebugCallbackDisabled 0

run AliasedCommands.con

softRun ../../../Tools/Editors/Editors.con

Make it look like this:

rem *** for BC
Game.GameLevelPath BFVietnam/Levels/Operation_Irving/
Game.useMenu 1
Game.useHud 1
Game.menuMain BattlefieldMenu
Game.menuInGame InGame
Game.menuMap Map
Game.DebugCallbackDisabled 0
Game.SoundBufferSize 400

run AliasedCommands.con

softRun ../../../Tools/Editors/Editors.con

    As you can see, I've added the line, Game.SoundBufferSize 400.
This is susposed to make the game not lag. It is said to work, 
but I'm not totally convinced. It may or may not work for you. It 
doesn't hurt to try it. When you are thru, hit save, not save as.
Open it up again to make sure it saved correctly.

    The next trick only works if you turn VERTICAL SYNC off. 
There are different ways of turn this off, depending on your video
card. Check the help guides on your system for more information.

    Open up the VideoDefault.con file with NOTEPAD. By default it
looks like this:

rem * TEMP *
renderer.FullScreen 1
renderer.fieldOfView 1
renderer.globalLodRadius 1
renderer.globalLodRadiusScaleFactor 5
console.showStats 0
renderer.allowAllRefreshRates 0

Make it look like this:

renderer.FullScreen 1
renderer.fieldOfView 1
renderer.globalLodRadius 1
renderer.globalLodRadiusScaleFactor 5
console.showStats 0
renderer.allowAllRefreshRates 1
renderer.lockfps 250

     Notice I've changed the allowAllRefreshRates to 1 and I 
added the line, renderer.lockfps 250. you don't have to put in 250,
but I've found this is the best and most stable number to use. 
Make sure you hit save, not save as, and close the file.

     If that doesn't help any, you can make the VideoDefault.con
look like this:

renderer.FullScreen 1
renderer.fieldOfView 1
renderer.globalLodRadius 1
renderer.globalLodRadiusScaleFactor 6
console.showStats 0
renderer.allowAllRefreshRates 1
renderer.useTrilinearFiltering 0
renderer.mipmapbias -3
renderer.lockfps 250

    Sometimes this can lower image quality, but in cases where you
can't get the game to run well at all, try the above settings.

BFV doesn't officially support higher resolutions like 1280x1024. There
is a way to force it though. 

First go to:
C:\Program Files\EA GAMES\Battlefield Vietnam\Mods\BfVietnam\

Change the line:
renderer.allowAllRefreshRates 0

To this:
renderer.allowAllRefreshRates 1

Then go to:
C:\Program Files\EA GAMES\Battlefield Vietnam\Mods\BfVietnam\settings

Edit the following files:

every time you see:
game.setDisplayMode 1024 768 32 85

edit it to whatever you like in this format:
game.setDisplayMode x=res, y=res, colordepth, refreshrate

e.g. game.setDisplayMode 1280 1024 32 75

Then set both files to read-only.
(if you don't want the settings getting changed).

If you are still using the default profile, instead of custom, 
then go to:
C:\Program Files\EA GAMES\Battlefield Vietnam\Mods\BfVietnam\

and follow the same steps as stated above.

    Sometimes fooling with that good old PAGEFILE can solve a lot
of problems. If you're running a dual-boot system, delete it on 
the side of WINDOWS that is not running. For instance, if you're 
running WINDOWS on your C drive, delete the one on your D drive, 
and vice-versa. Make sure you have show hidden files and folders
checked in your folder options, so you can see the PAGEFILE. 
Again, if you have a GB or more of RAM, I suggest having no 
PAGEFILE at all.

    If you don't like deleting things, here's another trick for 
clearing the PAGEFILE. Make sure you back up the REGISTRY before
you do this. Type REGEDIT in the RUN box. Navigate to this point:

Session Manager\Memory Management

Look for the registry string:


    Double click it and change the value to 1. Hit OK. Restart
your machine. Now the PAGEFILE will be cleared every time you 
shutdown or restart. Now it acts like RAM does, clearing itself, 
erasing any bad happenings. I must warn, that this does increase 
shutdown and restart times to about 40 seconds on average.


     BFV is a stellar game that should be enjoyed by everyone 
who plays it. EA makes it hard sometimes for us gamers, but 
maybe these tweaks will help you out a bit. Thank you for
