AMD FSR 3 vs. Nvidia DLSS 3: Similarities and differences

Due to their ability to get playable frame rates out of even relatively weak and old graphics cards, upscaling techniques such as AMD FidelityFX Super Resolution ("FSR") and Nvidia Deep Learning Super Sampling ("DLSS") are currently the talk of the town among gamers and developers alike. But where exactly are the similarities and differences? We have taken a look at the topic of upscaling using the latest AMD FSR 3.x and Nvidia DLSS 3.x offshoots as examples and explain them in detail below. AMD FSR 3.x goes back to AMD FSR 2.x, while Nvidia DLSS 3.x goes back to the first generation at its core. The first generation of AMD's FSR, on the other hand, was still a so-called "spatial upscaling," which had to manage entirely without a temporal component.
