Well, if you havent noticed- there is a "tunnel vision" type feel to the game and it can make you horribly motion sick. There is a fix to this and that horrible HDR bloom:

1) Go to My Documents>BFBC2
2) In there open Settings.ini (NOT Gamesettigns)
3) Find the setting called "bloom" and replace it so it says
Bloom=false
4) The last setting (the most important) is fov (frame of view). I recommend not going over 85 as it can horribly skew the image.
fov=75

This will help with the listed problems as well as prevent someone walking up to your side and knifing you, leaving you saying wtf since you never saw a thing.
