something that has always bothered me since OFP is the effect of when bullets hit the ground(the dust/dirt rising from the bullet energy impact). some of them are to small IMO especially on the larger calibre guns and just feel weak.
some examples where i defn feel it is way to small and can even hurt gameplay is when shooting the chopper mounted guns such as the m134 minigun. the impact effect is so small i cant even see where my bullets are hitting the ground when high in the chopper
sniper rifles cant see the bullet hitting the ground either in the distance it is so small
