According to the “Graphics & Performance Guide” article, published at GeForce.com, upcoming PC version of the Assassin’s Creed IV: Black Flag title will not only feature graphics enhancements such as HBAO+ , TXAA anti-aliasing or improved shadows, but also include GPU accelerated PhysX effects in a form of APEX Turbulence based smoke and steam.
If you played Batman: Arkham Origins, or checked out our “Batman: Arkham Origins Graphics & Performance Guide”, you’ll have seen the game-changing benefits our new GPU-accelerated PhysX APEX Particle system brought to the Batman prequel. In the not too distant future, an Assassin’s Creed IV: Black Flag game update will introduce APEX Particles that are manipulated by external forces such as gravity, wind, character movement, and explosions, courtesy of the APEX Turbulence system.
As in Batman: Arkham Origins, Assassin’s Creed IV’s APEX Particles will be further enhanced by the addition of Particle Shadow Mapping (PSM), which enables select particle effects to cast shadows, and self-shadow one another. This is particularly beneficial for thick, heavy smoke effects, such as Kenway’s smoke bomb, instantly emphasizing the density of the effect to the viewer, further increasing image quality.
However, one may notice that Turbulence effects won’t be avaialble at launch, but added later on in a patch.
