DirectX 12 Ultimate is described as “the culmination of the best graphics technology in the world, including DirectX Raytracing, Variable Rate Shading, Sampler Feedback, and the newly announced Mesh Shader.”, Microsoft has announced today.
The technology aims to make ray tracing and other visual effects more flexible and efficient, allowing for greater control over lighting effects while at the same time taking load off a CPU.
~Shawn Hargreaves at Microsoft.DirectX Raytracing (DXR) brings a new level of graphics realism to video games, previously only achievable in the movie industry. The effects achievable by DXR feel more real, because in a sense they are more real: DXR traces paths of light with true-to-life physics calculations, which is a far more accurate simulation than the heuristics based calculations used previously.
Hargreaves later elaborates on the subject of Variable Rate Shading.
