Depth of Field?

[DIGI Byte]

...When you focus on an object in the gameworld, your eye already creates DoF...

ok, shhh right there...

Mr. smarty... a DoF is a natural process of when your 2 eyes meet at a focal point...
a screen is a flat 2d surface... there IS no depth so it has to be simulated to get an effect...

not unless your mr imagination... you naturally don't get a DoF when you play a game between foreground and background elements because its just color on a flat surface, when your eyes flick around the screen, yes... but that's cause your looking at one corner like, but your not seeing depth focus and that's what your eyes cant do on a flat screen
