One key advantage for the RTX 20-series GPUs is the fact that they support Nvidia's Deep Learning Super-Sampling (DLSS) technology. While, at the time, DLSS was only of very limited utility, the ensuing two and a half years have seen DLSS get better and better, and get into more and more games, to the point where it is arguably the most important selling point for Nvidia's GPUs.
We didn't want to spend too much time testing DLSS performance further, as it is something we have looked at extensively since 2018 (see our various game analyses including Death Stranding, Cyberpunk 2077, Guardian's of the Galaxy, Doom Eternal and more).
We did, however, test three games at 1440p resolution, showing the performance with DLSS off (i.e. a native 1440p resolution), and then with DLSS Quality mode enabled for the RTX 2060 Super and RTX 2070 Super. Even when using the best quality DLSS mode (therefore giving the smallest performance boost), frame rates still jumped by 28-39% depending on the game. With so many modern titles now supporting the technology as well, it becomes impossible to revisit these GPUs without placing a strong emphasis on the importance of DLSS.
