As ray tracing becomes the predominant rendering technique in modern game engines, a single GPU RayGen shader can now perform most of the light simulation of a frame. To manage this level of complexity, it becomes necessary to observe a decomposition of shader performance at the HLSL or GLSL source-code level. As a result, shader profilers are now a must-have tool for optimizing ray tracing.
