I found a way to edit your field of vision so you can see more things around you and feel like your moving at a faster rate without the standard tunnel vision default setting.
There is not a way to do this ingame via options. So you will have to go into your "settings.ini" file in your BFBC2 folder. Just run a search for it. Then go to the bottom of the list and change the value to something higher. Mine for right now is 80 and it seems to work great. I'll probably play around with it for a bit more but it definitely makes playing the game easier and makes you a better player than everyone else.
