Nvidia has introduced a major update to its Deep Learning Super Sampling (DLSS) technology: DLSS 4, which promises to redefine gaming and rendering performance. This latest iteration brings Multi Frame Generation, new transformer-based AI models, and groundbreaking latency-reduction features, setting a new benchmark for GPU technology.
DLSS 4: Multi Frame Generation and Unmatched Performance Boost
Multi Frame Generation Explained
DLSS 4 introduces Multi Frame Generation (MFG), a transformative feature exclusive to the upcoming RTX 50 Series GPUs. With MFG, Nvidia claims the GPUs can generate up to three additional frames per traditionally rendered frame, multiplying frame rates by up to 8X compared to traditional rendering methods.
This unprecedented frame generation capability makes it possible to achieve 4K resolution at 240fps with full ray tracing—a milestone previously out of reach without compromising performance or visual fidelity.
How It Works
MFG works in harmony with the complete DLSS suite, including Super Resolution, Ray Reconstruction, and DLAA, to deliver unparalleled clarity and responsiveness. According to Nvidia, this new frame generation model is 40% faster and uses 30% less VRAM than its predecessor, thanks to its shift from Convolutional Neural Networks to transformer-based AI models.
Visual Improvements
The use of transformer AI models, similar to the technology behind AI tools like ChatGPT, results in:
- Less Ghosting: Improved handling of fast-moving objects in scenes.
- More Detail: Sharper textures and better object definition.
- Enhanced Stability: Smoother transitions and reduced flicker for a clearer overall picture.

Widespread Support and Early Adoption
Nvidia promises a robust launch for DLSS 4, with 75 games and apps supporting Multi Frame Generation at launch. Key titles like Alan Wake 2, Cyberpunk 2077, Indiana Jones and the Great Circle, and Star Wars Outlaws will support MFG when the RTX 50 Series GPUs debut in January 2025.
Additionally, more than 50 games will adopt the transformer-based DLSS features, which are compatible with all GeForce RTX GPUs, ensuring widespread availability across Nvidia’s ecosystem.
Reflex 2: Cutting Latency with Frame Warp Technology
In tandem with DLSS 4, Nvidia has announced Reflex 2, an updated low-latency technology that introduces Frame Warp to further enhance responsiveness in gaming.
How Frame Warp Reduces Latency
Frame Warp operates by dynamically adjusting the camera position during rendering. As the GPU processes a frame, the CPU predicts the next frame’s camera position based on the latest mouse or controller input. The rendered frame is then “warped” to match this updated position just before being sent to the display.
This ensures:
- Minimal Input Delay: The screen reflects the latest inputs, providing a more responsive experience.
- Reduced Latency: Nvidia claims Reflex 2 can cut latency by up to 75%, with testing in games like The Finals showing latency reductions from 27ms to 14ms.
Game Support
Reflex 2 with Frame Warp will debut in The Finals and Valorant for users with RTX 50 Series GPUs. Nvidia plans to expand Reflex 2 to other RTX hardware in the near future.

Compatibility and DLSS Override Features
Nvidia’s commitment to backwards compatibility ensures that DLSS 4 features will benefit a wide range of GPUs:
- Multi Frame Generation: Exclusive to RTX 50 Series GPUs.
- Transformer-Based DLSS: Available across all GeForce RTX GPUs.
For games that don’t immediately update to DLSS 4, Nvidia offers a DLSS Override option in its drivers and control panel. This allows users to force Multi Frame Generation and updated Super Resolution rendering on compatible titles.
DLSS Evolution: From 3.0 to 4.0
The introduction of DLSS 4 follows Nvidia’s steady refinement of the technology:
- DLSS 3 (2022): Brought Frame Generation to improve performance in games by interpolating new frames between rendered ones.
- DLSS 3.5 (2023): Introduced Ray Reconstruction, an AI-powered enhancement to ray tracing quality, and path tracing for select titles.
With over 600 games and applications now supporting RTX technologies, DLSS 4 represents the next leap in performance and visual quality.

Nvidia’s Vision for the Future
By combining Multi Frame Generation, transformer AI models, and Reflex 2, Nvidia is pushing the boundaries of what’s possible in gaming and real-time rendering. DLSS 4 not only promises a significant performance boost but also unlocks 4K 240fps gaming with ray tracing—once thought to be unattainable.
As the RTX 50 Series GPUs prepare for launch, DLSS 4 positions Nvidia as a leader in AI-driven rendering and low-latency technologies, ensuring an exciting future for gamers and developers alike.
Stay tuned for the RTX 50 Series launch and experience the power of DLSS 4 firsthand.
