From Digital Foundry: “Nvidia’s DLSS has gradually evolved into one of the most exciting technological innovations in the PC space. The idea is remarkably straightforward: the GPU renders at a lower native resolution, then an AI algorithm takes that frame and intelligently upscales it to a much higher pixel count. There’s an instant performance win, but remarkably, also a quality advantage too up against native resolution rendering. In the past, we’ve wondered whether this quality win comes down to mitigating the artefacts of temporal anti-aliasing – TAA – but the recent arrival of a DLSS upgrade to Nioh 2 provides us with an interesting test case. Nioh 2’s basic rendering lacks much in the way of any form of anti-aliasing at all. It’s pretty much as raw as raw can be. So the question is: can DLSS retain its performance advantage and still provide an actual increase to image quality up against native resolution rendering? Remarkably, the answer is yes.”
