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.

System Requirements
Operating System: Windows 10/11 (64-bit)
Graphics API: Vulkan-compatible GPU with VK_KHR_ray_tracing_pipeline extension
Hardware: GPU with VK_KHR_ray_tracing_pipeline extension (NVIDIA RTX Series or AMD/Intel cards supporting this extension)
Installation Guide
Please view Github Pages for detailed installation guides.
