I had almost abandoned Dead Space to my "so frustrated I will never play it again, let alone finish it" bin, which due to it being a digital download from Steam, simply meant it would drop off my Favorites list...
Then I fired it back up yesterday for one quick go. I was amazed at how utterly terrible the interface felt, not believing I'd endured several hours of it previously. It was worse than I remembered. "There's no way this is proper." I said to myself. Perhaps it needed to be played with a gamepad (due to poor control scheme porting), like a GTA game (driving a car with the mouse? Ha!) or Ghostbusters.
Nope, it just needed vSync turned off. Load times went from 30+ seconds to near instantaneous. All moving and aiming sluggishness and acceleration problems disappeared. Suddenly, the game was fun.
How could such a critical flag be:
??
Granted, vSync is a standard graphical flag, but never have I seen it impose such a drastic penalty on all aspects of a game by being on. 2000% longer load times? How does it even factor in to that???
I had the exact same issue. It's a very atmospheric game, but that VSync bug? Fail.
