Depth of Field?

[Renegade_]

Like I said: abused.
a) any non-novice small arms handler can reload without looking at the weapon

b) just imagine you're looking at something. and stop right there.
There's you DoF, au natural. Your eye doesn't focus differently just because you're looking at something on a screen. When you focus on an object in the gameworld, your eye already creates DoF, you don't need the game engine to interfere with a natural process. It would be as absurd as attempting to simulate head-related transform functions on a set of surround speakers.
