Like a lot of people, I was very worried/pissed off when I heard about the lazy port job that Dead Space 3 is suppose to have had. Having checked it out I can tell you its not that bad actually. Its got resolution options past 1900x1080 and a decent amount of custom options such as anti-aliasing and the like. It even includes full remapping for mouse and keyboard. Its pretty much on par with the options that Dead Space 1 and 2 had. Now if you were expecting something along the lines of Sleeping Dogs level of port, your going to be disappointed, but if you played Dead Space 1 or 2 on PC then you know what to expect. Everyone made it sound like it was going to be worse, but its not. Its totally ok.
Here, I even found a video some dude made that pretty much says the same thing.
