NVIDIA Demonstrates Why DLSS Is Better Than Spatial Upscaling Methods Such as AMD FidelityFX Super Resolution

NVIDIA has released their demo for how DLSS (Deep Learning Super Sampling) is superior to the current methods of upscaling, like AMD FidelityFX or MSAA. NVIDIA argues that it’s not just about the quality of image which they believe is better than these other methods, but also about performance efficiency and power consumption.

AMD FidelityFX Super Resolution is a method that can be used to improve the quality of the image by using an algorithm to increase the resolution of the game. NVIDIA, on the other hand, has demonstrated why DLSS is better than these methods.

NVIDIA has released a video demonstrating all of the new features in DLSS 2.3, the newest version of their deep learning super sampling technology. NVIDIA’s Bryan Catanzaro (Vice President, Applied Deep Learning Research) points out that spatial upscalers have been available for a long time and explains why they cannot compete in terms of picture quality. On its official website, AMD describes its FidelityFX Super Resolution technology as “a state-of-the-art spatial upscaling technique.”

Catanzaro says:

[…] There are certain drawbacks to using spatial upscalers. They operate frame by frame, considering each frame as its own picture before adding further pixels. They can add more pixels this way, but not more detail, therefore the results are often fuzzy and include additional temporal aberrations like flickering and crawling.

DLSS is a temporal approach that improves detail while reducing flickering. It’s simple to utilize information from numerous frames if nothing is moving since you can just stack the frames together to gain additional data. However, while you’re playing a game, everything move around and the aesthetic changes, including lighting and shadows, so it’s not as simple. DLSS mixes artificial intelligence with geometric motion vectors to make better judgements about whether information from previous frames may be reused.

Catanzaro continues with a few comparisons before pointing out some of the fundamental limitations of spatial upscaling approaches, such as the inclusion of temporal distortions. GeForce users may now play Cyberpunk 2077 and other games with the latest DLSS implementation.
