NVIDIA DLSS 3.5 - Why AI Enhancing Ray Tracing is Such a Big Deal

Published on 25 August 2023 at 10:14

DLSS 3.5 uses a neural network to upscale lower-resolution images to a higher resolution. The neural network is trained on a large dataset of images that have been rendered with ray tracing. This allows the neural network to learn how to identify and reconstruct the ray-traced effects in the images.

The Ray Reconstruction feature in DLSS 3.5 takes this a step further by using AI to improve the quality of ray-traced effects specifically. The neural network is trained on a dataset of images that have been rendered with ray tracing and then denoised. This allows the neural network to learn how to remove noise from ray-traced images while preserving the fine details.

What are the benefits of DLSS 3.5?

As I mentioned earlier, DLSS 3.5 can significantly improve the image quality and performance of ray-traced games. Here are some specific benefits:

Sharper images: DLSS 3.5 can significantly reduce the blurriness that can sometimes occur in ray-traced games. This is because the neural network is able to reconstruct the fine details that are lost when the image is downsampled.
More accurate lighting: DLSS 3.5 can also help to improve the accuracy of lighting in ray-traced games. This is because the neural network is able to learn how to simulate the way light behaves in the real world.
More realistic shadows: DLSS 3.5 can also help to improve the realism of shadows in ray-traced games. This is because the neural network is able to learn how to create shadows that are more consistent with the way shadows behave in the real world.
Improved performance: DLSS 3.5 can also help to improve performance in ray-traced games. This is because the neural network is able to upscale the image without sacrificing image quality. This can allow gamers to play at higher frame rates without having to turn down the ray tracing settings.
What are the limitations of DLSS 3.5?

DLSS 3.5 is a powerful new technology, but it does have some limitations. Here are some of the things to keep in mind:

It requires a GeForce RTX GPU: DLSS 3.5 is only available for GeForce RTX GPUs. This is because the neural network that powers DLSS 3.5 requires the Tensor cores that are found on GeForce RTX GPUs.
It can't be used with all games: Not all games support DLSS 3.5. However, NVIDIA is working to add support for more games in the future.
It can't be used with all ray tracing settings: DLSS 3.5 may not work as well with some ray tracing settings, such as ultra-high quality.
Overall, DLSS 3.5 is a powerful new technology that can significantly improve the image quality and performance of ray-traced games. However, it's important to keep in mind its limitations before you decide to use it.
