Seus: Shaders

: An experimental, high-end branch that implements a custom software-based ray tracing system.

: Sunbeams (god rays) and atmospheric lighting that reacts to the time of day and weather. SEUS Shaders

: It adds ray-traced reflections and realistic light diffusion from sources like torches, fire, and sea lanterns. Visual Features : An experimental, high-end branch that implements a

: Water and wet surfaces feature realistic reflections, with newer PTGI versions offering enhanced noise-killing filters for clearer images. : An experimental

SEUS is offered in two main branches, catering to different performance needs and hardware capabilities:

: It simulates how light bounces off surfaces in real-time without requiring a specialized NVIDIA RTX graphics card.
