Nvidia DLSS 3 on RTX 4090 - Exclusive First Look - 4K 120FPS and Beyond The latest video from Digital Foundry provides an exclusive first look into Nvidia's DLSS 3 technology featured on the RTX 4090 graphics card. This unveiling showcases the synergy of hardware advancements with cutting-edge software capabilities, specifically the addition of frame generation to the DLSS framework, which aims to enhance gaming performance significantly.

Overview of DLSS 3 Technology​

DLSS (Deep Learning Super Sampling) 3 builds upon its predecessor DLSS 2, introducing frame generation capabilities that deliver smoother gameplay experiences, particularly in high-refresh-rate settings. This technological leap allows for the interpolation of frames, creating additional frames between the traditionally rendered ones without requiring a linear increase in computational power. The video dives deep into the performance benchmarks of key titles like Marvel's Spider-Man, Cyberpunk 2077, and Portal RTX. It highlights how the integration of DLSS 3 can amplify frame rates and enhance visual fidelity while reducing latency in gameplay.

Key Innovations and How It Works​

1. Frame Generation: This new technology calculates an additional frame from the optical flow of pixels between two existing rendered frames, enabling a smoother visual output without the need for extra GPU cycles to render every frame natively.
2. Performance Metrics: Initial tests reveal that Marvel's Spider-Man can achieve frame rates between 100 to 120 FPS at native 4K resolution using DLSS 3, showcasing a dramatic improvement in performance compared to conventional methods.
3. Mitigating CPU Limitations: One of the standout features of DLSS 3 is its ability to alleviate CPU bottlenecks. By handling frame generation on the GPU, it helps maintain high frame rates even in CPU-intensive scenarios.
   

   Testing and Comparisons​

   The video provides side-by-side comparisons of games running with and without DLSS 3 across various scenarios. Notably, it captures the differences in graphical performance at varying resolutions and settings:
   • For example, in Cyberpunk 2077, moving from native 4K to DLSS performance modes resulted in frame rate multipliers exceeding 3.5 times, symbolizing how Nvidia's new technology can effectively enhance gaming experiences.
   • The video emphasizes that this transition to AI-generated frames isn't just beneficial for performance; it significantly reduces motion blur, enhancing the overall clarity and smoothness of animations.

   Pros and Cons​

   Advantages:​

   • Enhanced Frame Rates: The capacity to render up to 200 FPS in supported titles at 4K resolution dramatically elevates the gaming experience.
   • Lower Latency with Reflex: The inclusion of Nvidia Reflex technology ensures minimal latency, ensuring a competitive edge in fast-paced gaming scenarios.

   Disadvantages:​

   • Potential Artifacts: The pre-release software demonstrated that there could be some artifacting, especially with HUD elements and overlapping geometries, though Nvidia is actively working on these issues.
   • Dependence on Supported Titles: The efficacy of DLSS 3 primarily hinges on the games being programmed to utilize the technology effectively.

   Final Thoughts​

   DLSS 3 represents a significant stride in real-time graphics rendering technology, particularly for competitive gaming and high-end graphical workloads. As Nvidia continues to refine this technology, it promises to become a mainstay feature in future gaming developments. Readers, what are your thoughts on the evolution of DLSS technology?
