Any game that hovers between 30 and 60 fps will stutter - the effect of the stutter on the eyes depends on two things:
- How sensitive the individual's eyes are to the stutter
- The degree of motion blur or some other temporal trickery that can make games appear smoother than they are
KZSF was a stutter fest so thank GOODNESS for the recent 30fps lock update.
TR:DE also stutters as it can't quite reach 60fps much of the time. No 30fps lock as yet for that...
This generation could well be ruined by the quest for 60fops by developers. Unfortunately, having 1080p/60fps on a review or on the box just generates more sales. Even if the game can't attain 60fps for much of the time. If it gets there 'sometimes' that's enough for the marketing team to declare 60fps. And us poor gamers with sensitive vision get games that are near unplayable.
I have said this before and I will say this again. If near constant 60fps can't be reached, devs should focus on 30fps, turn on lots of graphical bells and whistles and add a little bit of motion blur to disguise the rougher motion. Or at least add a 30fps lock just like the KZ devs.
