DLSS 3 promises up to 4 times more performance

Today was the presentation of the new NVIDIA GeForce RTX 40 Series graphics cardswhere we have been able to see the GeForce RTX 4090 and 4080, but we have also been able to see the new generation of DLSS, and that is, in its third generation, It has a lot of promises to keep, based on what we’ve been able to see in the demos.

As we tell you in the headline, DLSS 3.0 promises up to 4 times more performance, and we can see this demonstrated in Cyberpunk 2077, where the game has been shown working in a traditional way with RayTracing at 24FPS, to later enable DLSS 3.0 and see how the game works much more fluidly, at 96 FPS. As we will see later, this is not even the maximum improvement that we can obtain with this version of DLSS.

Similar improvements of double the FPS have been seen in other titles such as Microsoft Flight Simulator, doubling the performance of the game, and this is done thanks to the possibility of introducing totally new frames without having to go through the whole process of rendering a frame in a traditional way using raster. This also implies that we can play at better resolutions and game qualities, In addition to being able to take advantage of techniques such as higher internal resolution in the game engine more efficiently.

The main component that enables this technique is a module called Optical Flow Accelerator, a name that may ring bells for users who have worked in video editing, and it is that the concept is the same, adding boxes from the available information to provide a much more fluid experience.

It should be noted that the performance that we can achieve from DLSS 3.0 is variable, because although some games “only” manage to double the performance, titles like Portal RTX achieve a performance increase of more than 550%, something that will allow us to play at very high speeds, especially if we take into account the raw performance increase of the new generation of graphics cards.

This will be ideal in titles that benefit from the frame rate, because for example we can quietly play slow games with frame rates of 30 or 60FPS, but titles like Portal or F1 2022 require much higher frame rates, so DLSS 3.0 comes to the rescue in these scenarios. However, this seems to be only possible in this new generation of graphics cardsso if we’re struggling to get good performance on 20 or 30 series cards, this will not be an option for us.

It should also be noted that the cases in which the frame rate doubles, it is usually because the limitation comes from the GPU, as we can read on the NVIDIA blog about itso in this case we would have two graphics updates for every graphics engine update, something useful for very CPU-heavy titles.

In the video above we can see this point illustrated, where Microsoft Flight Simulator simply doubles its frame rate despite being limited by CPU usage, who is extremely high on his physical motor, as at the time it was reported in the form of low performance.

Other titles, generally eSports, which are already capable of obtaining very high performance figures, surely they are not so positively affected by this technologyor if they do, it won’t be as helpful, considering that the last generation of graphics cards it could already run at higher speeds than many monitors on the market.
