Intel's Open Image Denoise library that is part of their oneAPI Rendering Toolkit as a set of open-source, high performance denoising filters for ray-traced images is out with a new release. Open Image Denoise is used by applications like Blender and with this version 2.3.3 release is expanded GPU support.

Most notable with Friday's release of Open Image Denoise 2.3.3 is extending the GPU support to NVIDIA Blackwell and AMD RDNA4 graphics processors. Open Image Denoise has already supported AMD and NVIDIA GPUs in addition to Intel graphics while this latest update simply extends that coverage to the latest-generation wares. Nice seeing Intel continuing to provide rather timely support for their competitor GPU architectures with their open-source software.

Open Image Denoise also brings performance improvements for existing AMD RDNA3 GPUs, adds new CMake build options, and also fixes a performance regression observed with older AMD RDNA2 GPUs. Open Image Denoise 2.3.3 can be downloaded from [1]GitHub . New [2]Open Image Denoise benchmarks soon.
