NVIDIA’s DLSS 4 takes AI-based upsampling to new heights with its multi-frame generation, creating even more artificial intermediate images and using a transformer network for clearer details. This innovation makes computer games more immersive and lifelike, catering to both casual and hardcore gamers. The integration of additional frame generations and a more advanced neural network ensures an unparalleled gaming experience, making it easier to run games at high resolutions with intricate ray-tracing effects.

What is Upsampling, Anyway?

Upsampling in gaming involves rendering a game at a lower resolution to boost frame rates and then scaling the results to the desired output. For example, a 4K monitor could render the game at 1440p, and GPU algorithms scale it up to 4K. Depending on the upscaling method, the actual render resolution could be significantly lower, reducing the load on the GPU.

Examples of Upscaled Gaming Technologies: Besides NVIDIA’s DLSS, other notable upscaling technologies include AMD FidelityFX Super Resolution (FSR), Intel Xess, and various third-party tools.

Transformer Instead of CNN: New Neural Network

Unlike previous versions, NVIDIA’s DLSS 4 leverages a transformer neural network (TNN) rather than a convolutional neural network (CNN). This new model captures motions and image content more globally, reducing ghosting and delivering more detailed images. It also improves ray reconstruction and deep learning anti-aliasing (DLAA), enhancing realism and performance in demanding games like “Cyberpunk 2077” and “Alan Wake 2.”

Multi-Frame Generation: Up to Three Artificial Frames

While DLSS 3 introduced frame generation (FG) by creating an artificial intermediate image per rendered frame, DLSS 4 goes a step further with multi-frame generation (MFG). This allows for up to three intermediate frames, leading to a potential significant boost in frame rates.

While effective for single-player gaming, this feature is more debatable for competitive shooters since it increases latency. To combat this, NVIDIA introduced Reflex 2, a technology aimed at solving latency issues, effectively integrating real-time generation and precision.

Older RTX Cards and Compatibility

DLSS 4 is optimized for the latest RTX-5000 GPUs, but older RTX-20 and RTX-30 series cards can benefit from its enhanced upsampling and ray reconstruction. These older models support DLSS Super Resolution, DLAA, and ray reconstruction based on the new transformer network, although the frame generation might be limited to one artificial frame.

For enthusiasts with older NVIDIA GPUs, there is still room for improved image quality and reduced ghosting. Over 75 games have already been verified to work with DLSS 4 at launch through the NVIDIA application, giving gamers an opportunity to enhance their experience with minimal effort.

Conclusion and Impressions

During recent tests, we evaluated the RTX 5070 TI under various settings, measuring FPS differences in games such as “Cyberpunk 2077” using different DLSS and frame generation modes. The average frame rate improvements showcased the effectiveness of DLSS 4, making it a practical solution for high-resolution gaming with ray-tracing effects. DLSS 4 undoubtedly offers an unparalleled user experience, especially noticeable in environments requiring heavy graphical rendering like competitive esports league matches and immersive story-driven games.

With DLSS 4, NVIDIA is notable compared to the CNN-based predecessor version in image quality. Especially in DLSS Quality, the result is now practically indistinguishable from native rendering, and even the performance level has far fewer visible flaws.

In conclusion, for gamers seeking a game-changing technology for immersive high-performance gaming, DLSS 4 with its multi-frame generation is an excellent upgrade, leveraging advanced AI and computational capabilities to deliver an unprecedented gaming experience.
