Likewise, hardware ray traced reflections and translucency, which have complex interactions with materials and lighting, will also see benefits. For large scenes, like the UE5 City Sample, traces are broken into the near and far field, which are run as separate tracing passes with compaction in between. An application can make use of both. Espaol - Latinoamrica (Spanish - Latin America). It also enables the decoupling of ray intersection and shading. Is there a different system for the shader cache now? While the ray tracing passes used in Lumen global illumination do not run a divergent hit shader, they still benefit from the mechanisms provided by SER. Because the Shader Cache only helps players improve their gameplay and has no negative side effects, it is best to leave the Shader Cache turned on during games rather than changing the setting.
