NVIDIA DLSS (Deep Learning Super Sampling) uses machine learning technology to intelligently scale on the fly, allowing a graphics accelerator, for example, to render a game at 1080p and then use AI to “stretch” the image to near-true 4K resolution. This allows you to greatly save resources due to the use of hardware tensor cores. DLSS 2.0 technology version implemented in some games demonstrates excellent results , but NVIDIA is not standing still.

DLSS 2.1 offers a new Ultra-Performance mode for 8K games, according to the company. NVIDIA claims DLSS 2.1 will enable the GeForce RTX 3090 to render games in 8K with the new 9x upscaling capability. In other words, in reality the game will be rendered at 1440p (2560 × 1440 pixels) and then scaled up to 7680 × 4320 on the fly using AI. As you might guess, Wolfenstein: Youngblood is one of the first games to get this feature on GeForce RTX 3090.

In addition, DLSS 2.1 will support VR. As a result, developers will be able to use smart scaling technology in their VR headset games. This was not possible in previous versions of DLSS and, hopefully, will improve picture quality by reducing system requirements.

Finally, DLSS 2.1 will receive support for dynamic resolution. The size of the input frame buffer can now be constantly changing, while the output can remain fixed. Therefore, DLSS can be used in games that have a pipeline of dynamic resolution to optimize performance.
