About this tag
The cuda 13.4 tag brings together coverage of NVIDIA’s CUDA-related work on emerging RTX hardware and Windows on Arm. Current posts focus on the RTX Spark platform, including reports of CUDA failures, gaming stutter, firmware and graphics-driver limitations on an unreleased Surface Laptop Ultra prototype powered by Arm-based N1X silicon. The archive also follows NVIDIA’s RTX Neural Texture Compression SDK, which adds early Windows 11 ARM64 support for developer testing while DLSS remains disabled. Together, these stories highlight the gap between prototype hardware potential and software readiness, as well as the developer tooling needed for future neural texture workflows on RTX systems.

    NVIDIA RTXNTC Adds Windows 11 ARM64 Support, DLSS Disabled

    NVIDIA has added Windows 11 ARM64 support to the RTX Neural Texture Compression SDK, giving developers an early path to build and test neural texture workflows for RTX Spark PCs before the platform’s expected fall 2026 arrival. The change is documented in NVIDIA’s RTXNTC GitHub build guide, and...

    NVIDIA RTX Spark Prototype Shows Gaming Stutter and CUDA Failures

    NVIDIA’s RTX Spark platform has arrived at a pivotal moment for Windows on Arm: an early Microsoft Surface Laptop Ultra prototype suggests the underlying N1X silicon has serious potential, yet its current firmware, graphics drivers, CUDA path, and game behavior are plainly not ready to...
