If your game is constantly Crashing:
- Make Sure you are running the game as Administrator

For a reported 10-20 fps boost:
- Edit using Notepad C:\Users\XXX\Documents\BFBC2\settings.ini
- Change "renderaheadlimit" to 0 instead of 2

For another potentially big performance update
-Edit using Notepad C:\Users\XXX\Documents\BFBC2\settings.ini
- Change "HSAO=true" to false

To run DX9 for improved performance (this also stops random crashes for some people):
- -Edit using Notepad C:\Users\XXX\Documents\BFBC2\settings.ini
- Change "DxVersion=auto" to "DxVersion=9" without quotations



For a reported giant general performance boost:
- Edit using Notepad C:\Users\XXX\Documents\BFBC2\settings.ini
- Change "Bloom=true" to false

Other settings.ini changes that you can try:
- Edit using Notepad C:\Users\XXX\Documents\BFBC2\settings.ini
- 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 Yaw Left/Right On Joysticks (from Necromancer on Steam)
1. Open Documents\BFBC2\Input\air.dbx with Notepad
2. Search for the string ConceptYaw
3. Below it look for this section:

Code:
<instance 
guid="EC8ED584-471E-473F-A0A7-865B5C15A6FF"  
type="GameSharedResources.PadInputActionData">
   
<field name="IsAnalog">true</field>
   <field name="NegateValue">false</field>
   <field name="Axis">IDA_Undefined</field>
   <field name="NormalizeInput">false</field>
   <field name="ScaleValue">1</field>
   <field name="UseSquareInput">false</field>
   <field name="Button">IDB_Undefined</field>
   <field name="Pov">IDP_POV_Undefined</field>
  </instance>
On the line <field name=”ScaleValue”>1</field> change 1 to -1


Changing Sound from Software to Hardware
In the GAMESETTINGS.INI change the following value

SoundSystemSize=1 to..
SoundSystemSize=2

1=software, 2=hardware. Apparently the the audio was designed to be a software engine mainly because of the console versions. I guess when switching it to hardware it dedicates all audio processing to 1 core which they didn't want to do on consoles (rumor?).


What ports should I open for multiplayer if I’m having connectivity trouble?
port 18390 TCP Outgoing
port 18395 TCP Outgoing
port 18395 UDP Outgoing
port 13505 TCP Outgoing
port 80 TCP Outgoing

**Unconfirmed**

UDP 22000 (This is only for LAN)
UDP range 23000-23009
# GameSpy Master Server UDP Heartbeat: Allow UDP Port 27900
# GameSpy Master Server List Request: Allow TCP Port 28900


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)
