ShadowLib provides improved(PCSS) to reach new levels of quality and performance, the ability to render cascaded shadow maps, and multiple spot lights. ShadowLib also offers (more information here) , the most advanced shadow algorithm ever offered by GameWorks. Frustum Tracing means that the primitives of occluding objects are ray-traced from the light’s point of view to form a shadow on the receiving surfaces. The result is a very crisp, accurate hard shadow, which is then softened using a variable penumbra filter as it extends away from the occluder.
