DLSS 3 Technology That Increases Performance Introduced, Here’s What’s New

NVIDIA has announced a new version of its Deep Learning Super Sampling (DLSS) upscaling technology during the launch of its RTX 4090 and RTX 4080 graphics cards. introduced. CEO Jensen Huang says surprisingly DLSS 3 can boost performance up to four times at native resolution.

More than 35 games and apps are already supported with DLSS 3. The worst part is that DLSS 3 will only be exclusive to RTX 4000 series cards with Ada Lovelace architecture. Rightfully so, gamers reacted strongly to NVIDIA’s decision. We don’t know for sure if this decision is due to hardware features or sales policy. However, when we look at the details, we see that there are some hardware innovations in the new architecture.

In a presentation, NVIDIA showed what DLSS 3 can offer in a game like Cyberpunk 2077. In video, the frame rate goes up to about 100 FPS when below 30 FPS. With the old DLSS 2 technology, the performance could go up to around 60 FPS. In another video, Microsoft Flight Simulator, one of the popular games, was shown. With DLSS 3, the frame rate climbs from 50s to 100 again. However, the exact graphics settings and resolutions of these tests have not been fully disclosed.

DLSS, which you are familiar with, is designed for games to offer more performance or better image quality on NVIDIA graphics cards. With technology powered by artificial intelligence, it is possible to achieve higher frame rates at the same resolution or higher resolution without sacrificing performance. DLSS runs the game at a lower resolution before machine learning techniques kick in to reach higher resolutions. When technology comes into play, things become different. For example, a game may appear to be running at 4K while running at 1080p internally.

In addition to GPUs, NVIDIA says DLSS 3 can have an impact on CPU usage and increase performance by up to 100%. In addition, this technology is now used to reduce latency times. NVIDIA Reflex It works in integration with. With DLSS 3, the upgrade logic also changes a bit. Optical Multi Frame Generation feature offers the ability to create completely new frames instead of just new pixels. The green team emphasizes that they can render up to 7/8 of a game’s pixels, which gives a huge boost in performance.

FPS increases aside, it is stated that DLSS 3 will offer better image quality. Optical Flow Accelerator feature of next-generation DLSS technology can track objects in scenes instead of just pixels; thus, graphic elements such as shadows can be detected better and the roughness is reduced to a lower level.

Details of DLSS 3 Technology

DLSS 3 is described as a revolutionary breakthrough in AI-powered graphics that greatly improves performance while maintaining image quality and responsiveness. The DLSS Frame Generation autoencoder handles 4 key data: game engine data such as current and previous game frames, an optical flow field generated by Ada architecture’s Optical Flow Accelerator, motion vectors, and depth.

The Optical Flow Accelerator analyzes two consecutive in-game frames and performs an optical flow area calculation. The optical flow field captures the direction and speed at which pixels move from frame 1 to frame 2. The Optical Flow Accelerator is capable of capturing pixel-level information such as particles, reflections, shadows and lighting that is not included in the game engine motion vector calculations. In the motorcycle example below, the movement flow of the motorcyclist accurately represents the shadow staying in roughly the same place on the screen relative to the motorcycle.

While the Optical Flow Accelerator accurately tracks pixel-level effects such as reflection, DLSS 3 also uses game engine motion vectors to precisely track the movement of geometry in the scene. The example below shows the game motion vectors accurately tracking (but not shadowing) the motion of the road passing by the motorcyclist. Creating frames using only motor motion vectors causes visual anomalies such as roughness in the shadow.

The DLSS Frame Generation AI network decides how to use information from game motion vectors, optical flow field, and sequential game frames to generate intermediate frames for each pixel. This network is able to accurately recreate both geometry and effects, using both motor motion vectors and optical flow (as seen in the image below) to track motion.

The AI ​​reconstructs three quarters of the first frame when DLSS 3 is enabled and the entire second frame using DLSS Frame Generation. As we just mentioned, seven-eighths of the total pixels displayed are reconfigured, greatly contributing to performance.

Performance Contribution of DLSS 3

Judging by NVIDIA’s claims, a four-card performance increase can be achieved in certain games and engines compared to traditional processing. Below are some test results with the RTX 4090:

DLSS 3 Supported Graphics Cards

Earlier versions of DLSS provided support stretching back to the NVIDIA RTX 2000 series. NVIDIA made no mention of this in their presentation. According to the information on the NVIDIA website, the new DLSS 3 will only be supported by RTX 4000 series graphics cards. Users with RTX 3000 series graphics cards will continue on their way with DLSS 2. In the company’s announcement, DLSS 3 technology was mentioned as follows:

Based on DLSS Super Resolution, DLSS 3 gets Optical Multi Frame Generation to create completely new frames and integrates with NVIDIA Reflex low latency technology for optimum response time.

DLSS 3 is powered by the new fourth-generation Tensor Cores and Optical Flow Accelerator of the NVIDIA Ada Lovelace architecture powering the GeForce RTX 4000 series graphics cards.

NVIDIA spokesman Benjamin Berraondo said in an email:

“DLSS 3 is powered by new fourth-generation Tensor Cores and Optical Flow Accelerator on GeForce RTX 4000 Series GPUs,” he said. It seems that older generation GeForce graphics cards do not have this special hardware required for DLSS 3. We don’t know the fine details of the architecture, but we have no choice but to believe these words from NVIDIA.


NVIDIA’s claims are huge. As you can see, the specified FPS increases are huge. However, we will see in time what the new version will offer in practice. Stay tuned to Technopat.net to see real world tests.

Hardware seems to be the reason why DLSS 3 is exclusive to the RTX 4000. However, this issue will be further clarified in the future. Users are very responsive to NVIDIA for this decision.

DLSS 3 will be released with support for more than 35 games and apps, the first of which was released in October. The GeForce RTX 4090 will go on sale on October 12, as you know.
