Here is a list of BC2 Tweaks and fixes I will update them as I find more, these are compliments of BadCompany2.com
Bad Company 2 tweaks
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 (especially with Quad Core users):
- 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. This map has a lot of it.
- Water=”medium” - Not really any water to traverse in this map, go ahead and set this to low.
- 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.

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.
How to adjust your FOV -Field of View *New in Retail
- Documents>BFBC2Beta and open up "settings.ini"
- Default is "FOV" variable is set to 55, but you can adjust that up to 120 (per repi)
Note: The FOV in the settings.ini file is the vertical FOV, people usually talk about horizontal FOV, so you have to convert your desired HFOV to VFOV using this calculator: FOV calculator. Enter your screen resolution in pixels (e.g. 1920×1200), then the desired HFOV, click calculate, and it will show you the VFOV setting you need to put in settings.ini.
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)
