NVIDIA Releases RTX Kit 2026.3 and RTX Mega Geometry 2.0 SDK for Developers

NVIDIA released RTX Kit 2026.3 and version 2.0 of its RTX Mega Geometry SDK, adding streaming continuous level-of-detail clusters for high-density meshes demonstrated in a textured glTF version of the Zorah demo. The RTX Kit update also includes RTX Character Rendering 1.4, RTX Dynamic Illumination 3.1 with DLSS Ray Reconstruction integration, RTX Neural Shading 1.4, and RTX Texture Filtering 1.3 with Collaborative Texture Filtering. RTX Neural Texture Compression 0.10 remains in beta but now supports the DirectX 12 Agility SDK preview with Linear Algebra, and both NTC and RTX Texture Filtering 1.3 add Windows ARM64 support ahead of RTX Spark PCs NVIDIA says ship in October.

NVIDIA has rolled out RTX Kit 2026.3 alongside version 2.0 of its RTX Mega Geometry SDK, giving game developers a fresh batch of neural rendering and path tracing tools. The headline feature is support for streaming continuous level-of-detail clusters for high-density meshes, shown off in a new textured glTF version of the Zorah demo. The rest of the RTX Kit update covers RTX Character Rendering 1.4, RTX Dynamic Illumination 3.1 with DLSS Ray Reconstruction integration, RTX Neural Shading 1.4, and RTX Texture Filtering 1.3, which adds Collaborative Texture Filtering. RTX Neural Texture Compression 0.10 is still in beta, but it now supports the DirectX 12 Agility SDK preview with Linear Algebra, letting Tensor Cores accelerate neural texture decompression in DirectX shaders. It and RTX Texture Filtering 1.3 also gain Windows ARM64 support, which seems to be groundwork for the RTX Spark https://www.techpowerup.com/352310/nvidia-n1x-comes-in-two-skus-20c-cpu-and-6-144c-gpu-or-18c-cpu-and-5-120c-gpu PCs NVIDIA says start shipping in October. NTC was already running on Windows on Arm https://www.techpowerup.com/351402/nvidia-neural-texture-compression-now-runs-on-rtx-spark back in August.
