A new patch available for the PC version of Assassin's Creed IV: Black Flag promises to introduce a "whole new level of realism" though new smoke physics, among features.
The patch adds PhysX Particles and Turbulence to improve the visual effects surrounding pistol and musket smoke, smoke bombs, and chimney smoke.
When the patch is applied, smoke will linger longer and be more voluminous. The smoke will also interact with characters and other game elements, including wind and rain.
Check out the video below for more on the new smoke effects and how they affect gameplay. For more on Assassin's Creed IV: Black Flag, check out GameSpot's review.
