NVIDIA’s deep learning super sampling technology, DLSS, currently features four modes: Ultra Performance, Performance, Balanced, and Quality. Unreal Engine 5 documentation has revealed that NVIDIA will be adding a fifth mode called Ultra Quality, which, as the name implies, provides the highest image quality possible. The input resolution and scale factor of NVIDIA’s DLSS Ultra Quality mode is unknown, but the input resolution and scale factor of Quality mode is 66.6 percent and 1.50x, respectively. NVIDIA’s new DLSS Ultra Quality mode is believed to be a response to AMD FidelityFX Super Resolution’s Ultra Quality setting.
Furthermore, it was discovered that a new version of DLSS is already present in the UE5 engine. Currently, the latest version available in games such as Rainbow Six Siege or Lego Builder’s Journey is DLSS 18.104.22.168. This version has been successfully imported into other games and has been confirmed to provide a better experience by reducing some unwanted artifacts. In most cases, it is really as simple as replacing a single DLSS file in the game directory.
