View Full Version : Tips tweaks and such

18th March 2010, 11:39 AM
A list of tips and tweaks from a thread on the official boards.

If youre running an ATI card and you find BC2 crashes on startup (no error)
- Go to battlefield bad company\BFBC2Game.exe and right click -> properties -> compatibility and "Run this program as an administrator"

To get an ATI frames boost:
- Set Catalyst A.I to max

For a reported 10-20 fps boost:
- Documents>BFBC2 and open up "settings.ini"
- Change "renderaheadlimit" to 0 instead of 2

For a reported giant general performance boost:
- Documents>BFBC2 and open up "settings.ini"
- Change "Bloom=true" to false

For another potentially big performance update:
- Documents>BFBC2 and open up "settings"
- Change "HSAO=true" to false (also settable in the in-game "advanced" graphics settings)

Other settings.ini changes that you can try:
- Undergrowth=”medium” – Put this to low, if experiencing frame-rate issues.
- Water=”medium” - Map has alot of water? Drop the quality for fps gains.
- MSAA=”2? - This is Anti-aliasing, this will always use up a lot of a gpx cards resources. Set this to “0?
- Shadows=”medium”- you can also set this to low to improve performance
- Textures=”medium”- Setting this to low can improve FPS at the cost of visual eye candy.
- Aniso=2 - Set this to 0 to disable Anisotropic filtering.

To fix sticky controls (for those who get key shadow/lag with wasd etc):
- Delete the joystick conrols under foot (options->controls->foot), then it works fine

To run DX9 for improved performance (this also stops random crashes for some people):
- Documents>BFBC2 and open up "settings"
- Add "DxVersion=dx9" to the list (without quotation)

You closed the PunkBuster agreement window and can't get it back:
- Head to Steam\steamapps\common\battlefield bad company 2\install\PunkBuster and re-install Punkbuster

To run the game in a window:
- Simply hit alt+enter and change your resolution to something smaller than your desktop.

For sticky/laggy mouse issues:
- Disable mouse acceleration in the game's mouse settings, and turn off Vsync in the graphics settings.

What ports should I open for multiplayer if I'm having connectivity trouble?
- Port: 80 TCP
- Port: 18121 TCP
- Port: 18126 TCP
- Port: 18126 UDP
- Port: 13505 TCP

What ports should I open for multiplayer if I'm having EA connection issues?
- 18390 TCP Outgoing
- 18395 TCP Outgoing
- 18395 UDP Outgoing
- 13505 TCP Outgoing
- 80 TCP Outgoing

You can't look up-down and/or left-right - "my mouse isn't working"
- You've accidentally bound something to the axes that BF2 uses for looking around.
- Reset your controls to fix this.
- In future, when binding things to your mouse, pay close attention; if you move the mouse at all while binding, it will register & bind that horizontal or vertical movement axes, replacing your look ones.

To enable war tapes audio:
- Change your audio setting to "war tapes" instead of "hifi"
An example of the change can be seen here:

A little more help on the FOV situation:

4:3 (1024x76http://forum.ea.com/eaforum/images/smilies/b2eb59423fbf5fa39342041237025880.gif
FOV90 (Recommended) = 74
FOV100 = 84
FOV110 = 94
5:4 (1280x1024)
FOV90 (recommended) = 78
FOV100 = 88
FOV110 = 98

16:9 (1280x720, 1920x1080)
FOV90 = 59
FOV100 = 68
FOV110 (Recommended) = 78
16:10 (1280x768, 1280×800, 1440×900, 1680×1050, 1920×1200, 2560×1600)
FOV90 = 65
FOV100 (Recommended) = 74
FOV110 = 84

For those who are playing BC2 in the same network as another person:
Many are experiencing getting kicked when a friend on LAN joins the same server. To fix this, in Steam:
- Go to Steam's My games menu
- Right-click on the BFBC2 and select Properties
- From the General tab, click the Set launch options button
- Add a different client port number on each machine between 27005 and 27032 in the following format:
- Code: +clientport 270XX (Where XX is a different number for each system - do not use 27020)

Great post Kreg.

Yes, indeedy.

Great post, thanks :thumbsup2:

Fantastic info, nice one. I'm off to use most of those right now!

18th March 2010, 01:54 PM
as i said its pretty much a copy paste off the official boards, i was looking for a solution to disable bloom (yeah i havent bothered looking the the ini file myself xD

Thanks Kreg. These can make a big difference to those struggling to run the game. Beware of changing renderahead. If your cpu and gpu are not working well together you may get more lag. It is easy to put back though if you get more lag. One last thing change your sound to headphones which is the lowest setting for sound quality. Strangely in the beta war tapes was below it.

Btw guys, when you actualy implant stuff from this topic report back how it changed your gameplay, since i think some dont know if they should change due to makeing the gameplay even worse.

So some feedback from our own members might be good.

Well most are really depending on what gear they have.. So the best way to find out if its something for you is to try it out, if it doesnt work for you, well change it back..

A setting like fov is all down to personal preference, i increased my fov a little, but not much...

I just fiddled around with the FOV after reading this thread. I'm not quite sure what to make of it. A bigger FOV will obviously let you see more of your surroundings on both sides of you, but it also puts stuff that's in front of you further away. I made two screenshots at the same spot in a map to compare:

(top: 55, bottom 74 FOV)

As you can see I can see more of the building to my left, which is good, but the building in front (well, slightly to the right) is further away. Imagine if there's a guy in one of the windows I want to shoot, I reckon I'll have a harder time of hitting him with a bigger FOV than I would with the default (smaller) FOV, no?

I haven't properly tested it while playing though, haven't had the chance yet. It's just something I was wondering about :g:

Great post and the Screenshots really do illustrate it perfectly.

I've always struggled deciding whether it's better to have a larger fov or the targets appearing closer to you which means it's easier to focus on and get them into your crosshairs.

For me, I guess I'd rather see less and have the potential target larger for quicker focusing on with the mouse.

Interesting though.
