About this Mod

Radiance

Important: This modrinth project contains only Linux versions of Radiance. For Windows versions, please view this modrinth project.

Radiance is a Minecraft mod that completely replace the vanilla OpenGL renderer with our Vulkan C++ renderer, which supports high performance rendering and hardware-accelerated ray tracing.
Due to the variety of C++ usage in the modern industrial rendering pipeline, a seamless integration of a modern industrial rendering module (such as DLSS and FSR) into our Vulkan C++ renderer is thus possible.
