Dof is OK if it is used in a way that makes sense to how we are looking at a screen. The only game I know that has done it well is alien isolation, where you can focus on either the motion tracker or your surroundings.
I haven't played it but from the description I presume it's like in Metro 1 with the clipboard, where you look down at the clipboard and everything else blurs.
I still hate it, though in Metro 1 the clipboard was out of focus as well laughably(not sure if they ever fixed it, not played it in so long). Not quite sure how it's done but I'm thinking in real life if I decide to lift my watch up and look at it, yes things in the distance will be less in focus but I can keep my watch up and decide to focus in the distance, throwing the watch out of focus despite being in the space where I'm looking.
That is what I hate about DOF, if I'm looking at my watch I'm not focusing on behind it so it's pointless to waste performance blurring it out but if I choose to keep the watch up but look beyond it, in real life my focus changes, in a game the game continues to chose to be focused on the thing in the foreground. That isn't realistic.
All these effects suck and worse still is the time and effort these idiots put into these effects which could be better spent on other things.
Probably 99% of gamers say they turn DOF/motion blur straight off, so why do devs think we want it. The biggest issue I find is that because these are treated as industry standard effects that must be in games then in all those games with crap graphical options these things are enabled by default without an easy way to disable them with Batman being the latest and most awful example.
If it became standard for these effects NOT to be used, then in those games where you don't get the options we will instead find they aren't enabled by default which would be a huge step forward. The industry is forcing rubbish effects that reduce IQ on gamers who don't want it. Rather than make 97% of sensible people turn it off, let the 3% of idiots turn them back on.
