The self-proclaimed BioShock mod of the century is here. Ever been bothered by the slow chugging animation in the original game? Either way, they're much improved now thanks to BioShock Physics Unlocker, which removes the 30 FPS cap tied into the physics aspect of the engine. As you can see from the comparison video here (be sure to watch at 720p or 1080p 60 FPS), it's much smoother unlocked.
Interested? You can download the mod and see installation instructions here. Not to worry: they're pretty straightforward.
