Battlefield: Bad Company 2 PC Tweak Guide

New updates to FOV and settings.ini after Day 1 Patch Below

Use FRAPs to display FPS in game
This game is CPU intensive with things like sound thrown at the processor it will not work on single core.
Performance should be much better for everyone now with full optimization and it will get even better after some patches and more stable.
All the items here should still work and help esp shadows and going to dx9.
Make sure you download the latest video drivers from Nvidia nd ATI. Use beta drivers at your own risk.
In Game Settings

1. Turn settings to lowest resolution and low setting
2. Turn sound down from hi-fi to headset (you will have to do this each time you load the game) BC2 uses a lot CPU for sound. If your PC can handle it wartapes is the best)

Settings File is located – Here

1. Change sound quality to low (also changeable in game menu but resets every time to hifi)
2. Change DXVersion-auto to 9 to force DX9
3. Change Bloom=true to false
4. Change HSAO=true to false (also settable in the in-game “advanced” graphics settings)helps esp with quad core
5. Change renderaheadlimit to 0 instead of 2 *New in Retail

Other settings.ini changes that you can try: (from BadCompanyTwo.Com)

1. - 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 force the use of all processors:
- Add “+fullproc” without the quotations to your desktop shortcut or Steam game’s “launch options”. (this should be active at release)
-You can go to Task Manager and manually heighten the priority to force it to use more CPU See Picture
To fix sticky controls (for those who get key shadow/lag with wasd etc):
- Delete the joystick controls under foot (options->controls->foot), then it works fine
To run the game in a window:
- Simply hit alt+enter and change your resolution to something smaller than your desktop.
To enable the Steam overlay on DirectX 10 and 11:
- Participate in the Steam client beta (Settings > Account > Beta participation).
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? (from EA UK forums)
- Port: 80 TCP
- Port: 18121 TCP
- Port: 18126 TCP
- Port: 18126 UDP
- Port: 13505 TCP
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.
Also if you are having problems there are beta drivers available that are supposed to fix some problems (ie reflective water with ati cards)..check the forums
If your game is constantly Crashing:
- Make Sure you are running the game as Administrator
If you have an ATI Card:
-Set Catalyst A.I to max
How to adjust your FOV -Field of View *New in Retail
-In your Settings.ini we showed you before in My Documents/BFBC2 the default is FOV=55 you can adjust that up to 120 (per repi)
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. -Thanks to Renegade from UK forums for this info -

Ok I did some screens of one area to check my FPS with different settings and it really sux on my laptop...

here is my specs if you want to be reminded lol
http://flyingright.net/forums/showth...0316#post10316

Singleplayer level: Snowblind

screen are in PNG format to show details and AA (about 1 meg in size)

First screen: Directx 10, 4x AA, 8x Anisotropy, Max details, Max res (1440x900) ----25fps



Second Screen: Directx 10, 2xAA, 2x Anisotropy, Lowest Details, Max res. ----38fps



Third Screen: Directx 9, No AA, 2x Anisotropy, Lowest Details, Max res. ----42fps



So thats how it runs on my laptop, cant compare to MW2 which runs like a dream with max settings, FPS above 50 and 60 all the time

what's your FPS in BFBC2?

dx9 and 10 just like mine, any card above 9800 like 260 is dx10.1 except for dx11 which is not released yet for nvidia

[SnakeDoctor]

So in your setting.ini i just change it to 10 then instead of 9.0c

yeh or set it to auto

I found out that when I use dx9 I cant see through some glass surfaces like the stationary machine gun :/

[SnakeDoctor]

So that is the fucking trouble i could not figure it out i looked at angels and she could but i could not
