Hi All,
I realize teh google has all this information on various forums, and yes the below was copy and pasted right off of a few of those forums. People are reporting the following as possible fixes/tweaks/help to their gameplay. Thought it may help some of you with your woes.
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.
- 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 (1024x76
-----
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)
Last but not least, is the speeding up of turret mouse movement. Go Here if you want that info.
Some of the above may be left overs from beta, some may not. As always be patient when tweaking. Change a setting, restart your game, check it out, repeat.
I found just turning off bloom (turned back on) and hsao increased my fps big time, so play with it (less than you do with yourself) and see what you can come out with.
