RTX 40-series GPUs let you turn on ray tracing and still hit high frame rates thanks to DLSS 3.
At GTC 2022 Nvidia unveiled the next step for its Deep Learning Super Sampling technology and it promises huge improvements to frame rates thanks to a complete rethinking of how it works. In fact, Nvidia claims its new DLSS 3 is capable of quadrupling frame rates compared to native.
There are four components to this new way of working though, and that means you're going to need either anor one of the new RTX 4080s in order to access this new DLSS technology. Core to this is a new Optical Flow Accelerator, which works with the game engine motion vectors, which show how pixels are changing, the convolutional AI frame generator and its Reflex super low latency pipeline to build those frames.
It processes the current frame and the previous frame to see how the pixels are changing to produce entire new frames. And it does so without processing the graphics pipeline, and that means it can benefit games that are both GPU-bound and CPU-bound. As can be seen from the graph above, DLSS 3 can have a massive impact to games. We'll have to see how this plays out when we get the new cards in our test rigs, but these are promising numbers at the very least. We'll have to see if there's any lag with creating several frames at once, but given Reflex gets a mention in the creation of the frames, we'd assume this is covered.
As Jen'Hsun succinctly put it when finishing off the segment on DLSS 3,"DLSS is one of our greatest neural inventions." And from the improvements shown in the games at GTC, he looks pretty spot on.Alan has been writing about PC tech since before 3D graphics cards existed, and still vividly recalls having to fight with MS-DOS just to get games to load. He fondly remembers the killer combo of a Matrox Millenium and 3dfx Voodoo, and seeing Lara Croft in 3D for the first time.
