This is really frustrating, not to mention surprising, given that DayZ is based off of a military sim
I suppose it probably can't be changed without some serious work being put into the engine though
Still, if it could be fixed or made less noticeable at all it would be a great improvement

The FOV slider is not a game-play mechanic, your fov should have no effect on the usefulness of scopes
Hopefully this will be rectified soon

I can also confirm that hit detection is extremely wonky for melee combat, hits regularly fail to land or are detected to the wrong body part, the only melee weapons that are currently really viable are the Axes, which usually result in one hit kills when a hit does manage to connect with the head

Hopefully this can be rectified before beta, because it makes the early game very difficult in a way completely unintended by the developers
