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 thingsworse. 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( 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 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 the ADVANCED tab. Select the PERFORMANCE SETTINGS. Click ADVANCED. 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.

While we're there, CONTROL PANEL, SYSTEM, ADVANCED, PERFORMANCE SETTINGS, VISUAL EFFECTS. Select ADJUST FOR BEST PERFORMANCE. This can help some slow moving systems, also.


*Make sure you have the latest patch for the game*

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 perfomance.

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


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. I'm not sure what OCCLUSION does. It may be what they call the DOPPLER AFFECT. Like when sound pitch changes depending on the distance it is to you. Mess with it, and see if you get any changes. 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\ BfVietnam\settings.

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 console.showStats 0 renderer.allowAllRefreshRates 0

Make it look like this:

renderer.FullScreen 1 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.

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:

HKEY_LOCAL_MACHINE\Software\System\CurrentControlSet\Control\ 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.
