Distractingly juddery is perhaps too extreme a way to put it. What I meant was that the game never feels completely smooth for me like other games unless, as I said earlier, it is running at a perfect 60 fps. If the framerate deviates just 1-3 fps from that, above or below, then I can feel the difference and see it in motion, especially when turning on the spot. And, yes, G-SYNC is ON at all times. I find it off-putting because I know that a game running over 60 fps on a system like mine with G-SYNC should feel so much better than this. The Witcher 3 at 4K and maxed out settings, including HairWorks, can dip to the low 50s fps but it feels super-smooth to play and the framerate dips are not noticeable even during combat when Geralt is rolling and jumping about at speed. It's just really disappointing that such a great game like Dishonored 2 should have this issue as it deserved better and I still think it is the engine choice that is to blame here. The number of complaints about performance in this game over on the Steam forums suggests that I am not alone in experiencing this.
