Nvidia Releases RTX Neural Texture Compression SDK for Windows 11 ARM64, Cutting VRAM Use by 85%

Nvidia has officially released its RTX Neural Texture Compression (NTC) development kit (SDK) for the Windows 11 ARM64 platform. The technology was first demonstrated in 2023, with further details disclosed in the first half of 2026, and can reduce video memory usage by up to 85 percent.

The RTX Neural Texture Compression technology employs low-bitrate compression, unlocking two additional levels of detail while maintaining storage requirements similar to traditional texture compression techniques, delivering up to 16 times texture pixel density. Through fused backpropagation optimization, the compressor takes between one and 15 minutes to process a set of 4K-resolution, nine-channel material textures on an RTX 4090 graphics card. As current 3D games continue to demand more video memory and the global microelectronics market faces a DRAM shortage, the technology holds practical significance for users with constrained hardware resources.

To date, no commercial game has officially announced support for the technology, with related applications still confined to technical demonstrations and sample projects. The RTX Spark chipset employs a unified memory architecture, configurable with up to 128GB of LPDDR5X memory, while the mainstream 32GB configuration can handle most workloads. Previous demonstrations have shown the chipset capable of running high-load titles such as Alan Wake 2 and PRAGMATA.

The first Windows 11 ARM64 dedicated driver was released alongside the SDK, with hardware products supporting the architecture nearing their launch date. Nvidia has now completed its software ecosystem, laying the groundwork for a new generation of ARM laptops in high-end graphics and AI rendering applications.
