NVIDIA brings its RTX texture compression SDK to Windows ARM64
As spotted by Compusemble, NVIDIA has added Windows 11 ARM64 support to its RTX Neural Texture Compression SDK. NVIDIA names RTX Spark as an example platform in the updated build guide, linking the change to its upcoming Windows on ARM hardware.
RTX Neural Texture Compression uses a small neural network to compress and reconstruct groups of material textures. The SDK can combine up to 16 channels, including albedo, normal, roughness, metalness and ambient occlusion, into one compressed texture set.

© NVIDIA DLSS and OptiX are not supported on Windows ARM64 and are disabled automatically. The remaining support shows NVIDIA is preparing more of its RTX development software for RTX Spark before the platform launches. Of course, this just seems temporary.
NTC is part of NVIDIA’s broader push into neural rendering through the RTX Kit developer suite. The SDK is available to developers, but NVIDIA has not announced any shipping game with NTC support as of August 2026. Its use is currently limited to NVIDIA samples, demonstrations and developer integration work.
