The ray tracing code has been completely rewritten since. It now supports bounces and can do the ray tracing on the GPU. The ray tracing code has been completely rewritten since. It now supports bounces and can do the ray tracing on the GPU. GPU ray
tracing requires a graphics card that has support for the Vulkan ray tracing API (for example, nvidia 10 series and higher). ZDRay
will automatically fall back to CPU tracing if no compatible GPU is found.
