Nvidia DLSS 4 promises performance gains of up to 8x

Among Nvidia’s announcements at CES 2025, the company revealed a significant advancement in its artificial intelligence super sampling technology, DLSS 4. This new feature promises to revolutionize gaming graphics performance, offering a more fluid experience with greater visual quality .

The technology will be available on the new RTX 50 series GPUs and brings a series of improvements compared to previous versions, further increasing the possibilities of ray tracing and high-resolution rendering.

What is DLSS 4?

Deep Learning Super Sampling (DLSS) is Nvidia’s rendering technology that uses artificial intelligence to increase graphics performance without compromising image quality.

With DLSS 4, Nvidia brings new features to make this process even more efficient, such as Multi Frame Generation capabilities. This new functionality allows you to generate up to three additional frames for each traditionally rendered frame, multiplying the frame rate per second (fps) by up to 8 times.

This evolution makes 4K gameplay at 240 fps with ray tracing completely complete, a goal that previously seemed distant. The new feature brought a significant leap in the gaming experience, bringing more fluidity and graphic quality.

Benefits and technical advances

The big new feature of DLSS 4 is the ability to generate multiple additional frames, which guarantees much higher frame rates. To achieve this performance, Nvidia replaced old Convolutional Neural Networks (CNN) with transformer models, the same ones used in generative AI tools such as ChatGPT.

This replacement ends up bringing significant improvements in image quality, reducing ghosting, increasing details and bringing more stability to the scenes.

The new frame generation model is 40% faster than the previous one and uses 30% less VRAM, which makes the technology more efficient and accessible for a wider variety of devices.

Furthermore, DLSS 4 is not just limited to new GPUs. Nvidia has confirmed that games supporting Ray Reconstruction, Super Resolution and DLAA will be able to be updated to take advantage of the new AI models on any RTX series GPU.

Support and compatibility

At launch, DLSS 4 will feature support for 75 games and applications, including prominent titles such as Alan Wake 2, Cyberpunk 2077, Indiana Jones and the Great Circle, and Star Wars Outlaws.

When the RTX 50 Series GPUs launch at the end of January, these games will be ready to take advantage of the new features. Additionally, more than 50 games will support the new transformer-based AI models, allowing even older GPUs to take advantage of the technological advancement.

For games and applications that have not yet been updated, Nvidia revealed that it will offer an option called DLSS Override in the drivers and in the Nvidia app. This functionality will force Multi Frame Generation on compatible GPUs, even if the game does not yet have official support for DLSS 4. This means that players will be able to enable the new feature in games that already support DLSS 3, ensuring an immediate performance gain .

Reflex 2 and latency reduction

Another important point announced in addition to DLSS 4 is Reflex 2, an update to Nvidia’s latency reduction technology. The new version comes with the Frame Warp feature, which can reduce latency by up to 75%.

Frame Warp calculates the camera position based on player input (mouse or controller) and applies adjustments to the rendered frame before it hits the screen. This process happens as late as possible, ensuring that the player’s movement is instantly reflected in the game.

Nvidia tests show that Reflex 2 reduced latency from 27ms to 14ms in titles like The Finals. This technology will first be available to gamers with RTX 50 series GPUs, but will later be expanded to other GPUs in the RTX line.
