It hurts my eyes to be honest (I am not joking) I hate blurry stuff, my eyes can't handle them anymore and now it seems like they stick a faint blurry orange tint on top of everything... Also for the same reason I can't play games with DoF.
I also never understood why games even have DoF for that matter, my eyes do not need artificial blurriness, they already have natural DoF, if I look at the center of the screen the edges get naturally blurred, and if I look at one edge of the screen the rest is also naturally blurred (because that is how eyes work), so what is with this fixation on games to make me only see the damn center of the screen? Do game devs think people eyes are lazy and so they need to help blur the screen? but what if I want to look past that NPC I am talking? or look at the left even though my character is facing forwards (we can move our eyes even if we don't move our head or entire body like in the game), we can't because then for some reason everything is blurred... I don't like to say this but it totally breaks my "immersion" and gives me headaches and makes my eyes tear too...
Ooops... sorry for the rant, I just woke up and am grumpy...
