Dynamic Super Resolution, or DSR, is an image downscaling technology that has been available in GeForce Game Ready drivers for a while now. It is the opposite of the ever-popular DLSS which actually upscales the image after rendering it at a lower internal resolution. DSR renders at a higher resolution and then downscales it to match the video output of your monitor. Today, NVIDIA announced an AI-powered update to DSR and its coming in the next Game Ready drivers.
DSR but with the DL
Deep-Learning Dynamic Super Resolution is a new downscaling tech, or rather a refreshed one, that will make its way to GeForce drivers on January 14th along with a bunch of other additions. As the name suggests, this is just standard DSR but with Deep-Learning chops behind it. That means the Tensor cores found inside GeForce RTX graphic cards will be put to use here to boost DSR with the help of AI and machine learning.
The goal here is to provide a FPS count equivalent of native 1080p resolution but with an increased graphical fidelity that exceeds even 4K resolution. On top of that, NVIDIA is saying DLDSR 2.25x is equal to DSR 4x in terms of image quality but the performance is significantly improved upon. As seen in the screenshot below, DLDSR 2.25x looks as good as DSR 4x but offers considerably more frames, pretty much matching the native 1080p FPS.
As such, DLDSR is supposedly almost twice as efficient while maintain similar quality. In the screenshot above, you can see that DSR is rendering at 4K then downscaling to 1080p. Whereas, DLDSR is actually rendering at just 1620p then downscaling that to 1080p. All while having a healthy lead in FPS and no discernible difference in quality. That’s where the prowess of the AI network really shines.
DLDSR will work in most games as it’s essentially just a filter on top of the game, so as long as you have a RTX graphics card, you’re good to go. The feature will be added to the GeForce drivers in the upcoming Game Ready driver releasing on January 14th. In that new driver, there’s another criminally-underappreciated addition and that is new custom ReShade filters.
For the uninitiated, ReShade is an incredibly popular post-processing graphics tool that lets you apply a bunch of filters on top of a game to control various aspects of it such as lighting and textures. NVIDIA has partnered up with ReShade modder Pascal Gilcher to add new modified versions of iconic ReShade filters within the GeForce driver itself. You will be able to apply these via the Freestyle overlay in GeForce Experience.
- SSRTGI (Screen Space Ray Traced Global Illumination), commonly known as the “Ray Tracing ReShade Filter” enhances lighting and shadows of your favorite titles to create a greater sense of depth and realism.
- SSAO (Screen Space Ambient Occlusion) emphasizes the appearance of shadows near the intersections of 3D objects, especially within dimly lit/indoor environments.
- Dynamic DOF (Depth of Field) applies bokeh-style blur based on the proximity of objects within the scene giving your game a more cinematic suspenseful feel.
NVIDIA says with DLDSR and SSRTGI combined, you can enjoy a “remastered experience” in classic games like Prey. These will also debut on the new Game Ready driver releasing on January 14th. It’s interesting to see NVIDIA come out of nowhere with an announcement like this, just days after AMD announced its new image upscaling tech, Radeon Super Resolution. Perhaps, NVIDIA just can’t see anyone else have a moment of spotlight in the image scaling space as the same happened with NIS just a few months ago as well when AMD’s FSR was having a moment to shine.
