Alongside the new Ampere graphics cards, NVIDIA also announced RTX IO, which is a new "suite of technologies" that enable fast GPU-based loading and game asset decompression.

Based upon Microsoft's upcoming DirectStorage API, NVIDIA's RTX IO technology will tap into the processing prowess of GPUs to speed up game loading.

NVIDIA said:

Leveraging the advanced architecture of our new GeForce RTX 30 Series graphics cards, we’ve created NVIDIA RTX IO, a suite of technologies that enable rapid GPU-based loading and game asset decompression, accelerating I/O performance by up to 100x compared to hard drives and traditional storage APIs. When used with Microsoft’s new DirectStorage for Windows API, RTX IO offloads dozens of CPU cores’ worth of work to your GeForce RTX GPU, improving frame rates, enabling near-instantaneous game loading, and opening the door to a new era of large, incredibly detailed open world games.

According to NVIDIA, this technology can reduce object pop-in and stutter, and enable high-quality textures to load rapidly.

This end result is that large open world games will load smoothly even if you are speeding through it, meaning none of this nasty drawing effect as you rushing through the world.

Furthermore, NVIDIA says RTX IO can reduce game download and install sizes, which in turn means gamers can keep more games on their SSDs.

While this all sounds very promising, Microsoft only expects to roll out developers previews of DirectStorage next year, so it will won't be until the later half of 2021 that will start seeing games take advantage of this new technology.

If it's any consolation, RTX IO will run on both Ampere and Turing GPUs, which means owners of existing GeForce RTX 20-series cards will be able to enjoy this new technology.
