You don’t need to look further than the install size to see that RTX IO is working. This is all great in theory, but GPU decompression is uncharted territory on PC - even with games like Forspoken that support DirectStorage. None of this is proprietary, either there’s been plenty of finger-wagging at Nvidia over its (now open-source) Deep Learning Super Sampling, but RTX IO works on any DirectX 12 graphics card. RTX IO works on top of DirectStorage, and it even supports Vulkan extensions, allowing it to work in games like Portal: Prelude RTX. If you keep up with this tech, you can probably spot the similarity to Microsoft’s DirectStorage. It’s passed through GDeflate, Nvidia’s open-source data compression scheme built for GPUs, and it’s immediately ready at the GPU. NvidiaĬompressed data comes off the SSD into system memory and it goes straight to the GPU. The storage inside PCs these days is fast enough to keep up with this level of streaming, but they lack the dedicated decompression hardware to make it work. Assets are decompressed faster, and therefore, arrive at the GPU faster. This system worked for a long time, but there’s a problem with it now: the PS5 and Xbox Series X.Īs I’ve written about previously, both the PS5 and Xbox Series X have dedicated decompression hardware that cuts the CPU entirely out of this process. Once the full asset is ready, it’s sent to the graphics card. They cycle out of memory onto your CPU for decompression before returning to the memory. ![]() When games typically load, assets are taken off the SSD and loaded into system memory.
