Medal of Honor Warfighter Mouse settings

Is there anyway of lowering the DPI when sighting with a weapon?

I know BF3 Dose it but MOH dosent and its very anoying when trying to aim. Can i get the mouse settings from BF3 and use them on MOH or is it totaly diferent game?

Its very bad when useing the second scope and it just feals so jittery 

If you have a high end gaming mouse then usually they will have on the fly profile/dpi changer buttons like my deathadder 3500 as for it being like that in bf3 I notice that too but you really cant do much other than change your sensitivity using one of the hardware buttons on your mouse or changing the in game sensitivity when you want to snipe. 

Hope it helped!
