While not as hyped as the real-time ray tracing features, the new DLSS (deep learning super-sampling) anti-aliasing technique introduced with the RTX 2000 GPUs was supposed to further improve image quality via AI calculations. However, this hardware feature is still in its infancy and is not yet working properly, as pointed out by gamers who tested it in resolutions lower than 4K. 3DMark's latest test proves that the results can indeed be outstanding, but the implementation in actual games like Battlefield V and METRO Exodus is lacking for the time being. Nvidia is aware of these problems and is willing to improve DLSS compatibility in upcoming driver updates.
Some of the artifact reported by gamers in resolutions lower than 4K include blurry frames, stuttering and over-sharpening. Nvidia explains that DLSS was initially designed to work best at 4K resolutions: “Running at 4K is beneficial when it comes to image quality as the number of input pixels is high. Typically for 4K DLSS, we have around 3.5-5.5 million pixels from which to generate the final frame, while at 1920x1080 we only have around 1.0-1.5 million pixels. The less source data, the greater the challenge for DLSS to detect features in the input frame and predict the final frame.”
Moreover, Nvidia specifically stated that it acknowledges these problems and improvements are on their way: “We have seen the screenshots and are listening to the community’s feedback about DLSS at lower resolutions and are focusing on it as a top priority. We are adding more training data and some new techniques to improve quality and will continue to train the deep neural network so that it improves over time.”
It is not yet clear when exactly Nvidia intends to release the DLSS fixes, but at least we now know the green team is hard at work on improving things. Imagine if there were tens of games supporting DLSS and all had this problem.
