Intel's Open Image Denoise open-source software that is a denoising library used by Blender and other applications is out with a new feature release as it prepares for the integrated graphics of upcoming Arrow Lake and Lunar Lake processors as well as nearing the launch of Xe2 / Battlemage discrete graphics.

This CPU/GPU denoising library is up to version 2.3 this morning. Open Image Denoise 2.3 in addition to the Arrow Lake / Lunar Lake / Battlemage hardware support brings significantly improved image quality using the ray-tracing filter in the high quality mode, a new "fast" quality mode for around 1.5~2x better performance for interactive/real-time previews, async functions now execute asynchronously on CPU cores too, new API functions, and more.

Downloads and more details on today's Open Image Denoise 2.3 release via [1]GitHub . I'll be working on new [2]Open Image Denoise benchmarks shortly with the latest CPUs and GPUs.
