U can try this Champ


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.



Hope it helps.
