![]() If you stick with this technology, you can probably draw an analogy with Microsoft’s DirectStorage. It is passed through GFlate, an open-source data compression scheme created for Nvidia’s GPUs, and is instantiated on the GPU. That’s where RTX IO comes in.Ĭompressed data comes from the SSD into system memory and it goes directly to the GPU. These days the storage inside PCs is fast enough to keep up with this level of streaming, but there’s a lack of dedicated decompression hardware to make it work. Assets are faster to decompress, and therefore, faster to access on the GPU. This system worked for a long time, but now it has a problem: the PS5 and Xbox Series X.Īs I’ve written before, both the PS5 and Xbox Series X have dedicated decompression hardware that completely separates the CPU from the process. Once the entire asset is ready, it is sent to the graphics card. They are cycled from memory to your CPU for decompression before being returned to memory. When games normally load, assets are removed from the SSD and loaded into system memory. It takes advantage of the massive core count available on the graphics card, by offloading some of the work that should be done by your CPU to the GPU. It’s GPU-accelerated asset loading and decompression promises faster load times, smaller install sizes, lower CPU usage, and fewer texture pop-ins. Portal: Prelude RTX | RTX IO Off vs On Comparison – Cake Viewįirst, let’s talk about what RTX IO is. But according to my testing, RTX IO may have a greater impact on PC gaming than any other RTX features. It is not as flashy as ray tracing or DLSS, works in the background and provides many benefits without drawing attention to them. ![]() But lo and behold - this is the first game we’ve seen with Nvidia’s new RTX IO, a feature that was announced nearly three years ago. ![]() You wouldn’t suspect it’s like a mod Portal: Prelude RTX It will offer a great deal of kit for the future of PC gaming.
