HIP is now used as the backend for Radeon ProRender’s RPR – Final render mode, although the legacy OpenCL backend is still available for older GPUs.Īlthough the change may result in a “slight performance boost on some cards”, the main reason is the decline of support for OpenCL within CG software development.Īll three plugins: better intective rendering In addition, interactive rendering mode RPR – Interactive – which uses Vulkan rather than HIP or OpenCL – has been updated to brings its output closer to RPR – Final.
Interactive rendering now uses the Nvidia-developed global illumination algorithm ReSTIR for direct lighting, and AMD’s own FSR 2 technology for render upscaling. RPR – Interactive is also now better supported on older GPUs without dedicated ray tracing cores, and cards with less than 8GB of graphics memory. Other key changes include support for displacement, and better support for MaterialX: RPR-Interactive supports all of the materials in AMD’s free online MaterialX material library.
