NVIDIA Ships Vulkan Extensions to Support Accelerated RTX™ IO on Windows and Linux

NVIDIA RTX™ IO is a suite of technologies that enables rapid GPU-based asset decompression and loading. NVIDIA’s GDeflate GPU decompression format delivers IO-saturating performance on modern NVMe devices. GDeflate is used in Microsoft’s DirectStorage API, and now NVIDIA is contributing the technology for consideration by the Vulkan working group at Khronos. Two new NVIDIA Vulkan extensions to accelerate RTX IO are were released in the Vulkan 1.3.233 update and are supported in the latest NVIDIA drivers on both Linux and Windows. VK_NV_memory_decompression handles decompressing assets on GPU, and VK_NV_copy_memory_indirect handles copying decompressed data to Vulkan buffers/images.
