NVIDIA DLSS 4 Introduces Multi Frame Generation & Enhancements For All DLSS Technologies

NVIDIA DLSS is a suite of neural rendering technologies powered by GeForce RTX Tensor Cores that boosts frame rates while delivering crisp, high-quality images that rival native resolution rendering, as part of over 700 RTX games and apps.

At CES 2025, we’re advancing DLSS once again with the introduction of DLSS 4, featuring Multi Frame Generation for GeForce RTX 50 Series graphics cards and laptops; 75 games and apps will have support for Multi Frame Generation when they’re released.

DLSS Multi Frame Generation generates up to three additional frames per traditionally rendered frame, working in unison with the complete suite of DLSS technologies to multiply frame rates by up to 8X over traditional brute-force rendering. This massive performance improvement on GeForce RTX 5090 graphics cards unlocks stunning 4K 240 FPS fully ray-traced gaming.

DLSS Multi Frame Generation: Multiply Performance With GeForce RTX 50 Series GPUs

DLSS 3 Frame Generation’s AI model uses game data such as motion vectors and depth, and an optical flow field from the GeForce RTX 40 Series Optical Flow Accelerator to generate one additional frame. Generating multiple frames was cost prohibitive since both the Optical Flow Accelerator and the AI model would be required for every new generated frame, and the performance cost would throttle the GPU, resulting in lower input frame rates.

DLSS 4 Multi Frame Generation combines multiple Blackwell hardware, and DLSS software innovations to make generating multiple frames a reality.

Our new frame generation AI model is 40% faster, uses 30% less VRAM, and only needs to run once per rendered frame to generate multiple frames. For example, in Warhammer 40,000: Darktide, this model provided a 10% faster frame rate, while using 400MB less memory at 4K, max settings, using DLSS Frame Generation.

We have also sped up the generation of the optical flow field by replacing hardware optical flow with a very efficient AI model. Together, the AI models significantly reduce the computational cost of generating additional frames.

Even with these efficiencies, the GPU still needs to execute 5 AI models across Super Resolution, Ray Reconstruction, and Multi Frame Generation for each rendered frame, all within a few milliseconds, otherwise DLSS Multi Frame Generation could have become a decelerator. To achieve this, GeForce RTX 50 Series GPUs include 5th Generation Tensor Cores with up to 2.5X more AI processing performance.

Once the new frames are generated, they are evenly paced to deliver a smooth experience. DLSS 3 Frame Generation used CPU-based pacing with variability that can compound with additional frames, leading to less consistent frame pacing between each frame, impacting smoothness.

To address the complexities of generating multiple frames, Blackwell uses hardware Flip Metering, which shifts the frame pacing logic to the display engine, enabling the GPU to more precisely manage display timing. The Blackwell display engine has also been enhanced with twice the pixel processing capability to support higher resolutions and refresh rates for hardware Flip Metering with DLSS 4.

Working in concert, our new hardware and software innovations enable DLSS 4 to generate 15 out of every 16 pixels with great image quality, smoothness, and latency.

For games and apps, DLSS 4 with Multi Frame Generation, Ray Reconstruction, and Super Resolution multiplies frame rates by up to 8X over brute-force rendering, and boosts frame rates by up to 1.7X when upgrading from Frame Generation to Multi Frame Generation.

The New Transformer Model – Image Quality Improvements For All GeForce RTX Gamers

DLSS 4 features a major architecture upgrade for DLSS Ray Reconstruction, DLSS Super Resolution, and DLAA with the graphics industry’s first real-time use of a transformer-based model.

Previously, DLSS used Convolutional Neural Networks (CNNs) to generate new pixels by analyzing localized context and tracking changes in those regions over successive frames. After six years of continuous improvements, we’ve reached the limits of what’s possible with the DLSS CNN architecture.

Our new DLSS transformer model uses a vision transformer, enabling self-attention operations to evaluate the relative importance of each pixel across the entire frame, and over multiple frames. Employing double the parameters of the CNN model to achieve a deeper understanding of scenes, the new model generates pixels that offer greater stability, reduced ghosting, higher detail in motion, and smoother edges in a scene.

In intensive ray-traced content, the new transformer model for Ray Reconstruction delivers a big uplift in image quality, especially in scenes with challenging lighting conditions. For example, in these scenes from Alan Wake 2, stability is increased on the highly-detailed chainlink fence, ghosting on the fan blades is reduced, and shimmering is eliminated on the power lines, improving the player’s immersive experience in the third-person game.

75 Games & Apps With Multi Frame Generation On Day 0

Alan Wake 2, Cyberpunk 2077, Indiana Jones and the Great Circle™, and Star Wars Outlaws™ will be updated with native in-game support for DLSS Multi Frame Generation when GeForce RTX 50 Series GPUs are launched. Black Myth: Wukong, NARAKA: BLADEPOINT, Marvel Rivals, and Microsoft Flight Simulator 2024 are following suit in the near future. And Black State, DOOM: The Dark Ages, and Dune: Awakening are all launching with DLSS Multi Frame Generation.

For many games that haven’t updated yet to the latest DLSS models and features, NVIDIA app will enable support through a new DLSS Override feature. Alongside the launch of our GeForce RTX 50 Series GPUs, after installation of a new GeForce Game Ready Driver and the latest NVIDIA app update, the following DLSS override options will be available in the Graphics > Program Settings screen, under “Driver Settings” for each supported title.

• DLSS Override for Frame Generation – Enables Multi Frame Generation for GeForce RTX 50 Series users when Frame Generation is ON in-game.
• DLSS Override for Model Presets – Enables the latest Frame Generation model for GeForce RTX 50 Series and GeForce RTX 40 Series users, and the transformer model for Super Resolution and Ray Reconstruction for all GeForce RTX users, when DLSS is ON in-game.
• DLSS Override for Super Resolution – Sets the internal rendering resolution for DLSS Super Resolution, enabling DLAA or Ultra Performance mode when Super Resolution is ON in-game.

Upgrading and enhancing games takes just a few clicks in NVIDIA app:

NVIDIA app DLSS Override game support will be expanded as we finish testing the new models in more titles.

NVIDIA DLSS 4: The Best Gets Better

NVIDIA DLSS has revolutionized gaming with its ever-improving AI technologies, multiplying performance, increasing image quality, and enhancing ray-traced graphics further than anyone imagined possible when we first debuted RTX and DLSS back in 2018. With the launch of DLSS 4 alongside GeForce RTX 50 Series GPUs, all GeForce RTX desktop and laptop gamers will receive upgrades, making their games and apps even better.
