NVIDIA DLSS 3 Frame Generation technology comes with a certain number of reference performance presets by NVIDIA, which game developers can integrate into their game engines. These presets essentially trade quality for performance across tiers, and are lettered, as detailed in the screenshot below. DLSS 3 doesn't just built on the image upscaling technologies of DLSS 2, but adds the all-important Frame Generation component, which generates entire alternate frames using AI, and without the involvement of the raster graphics machinery. NVIDIA Reflex is also involved, to reduce the graphics latency cost this imposes.
A side-effect of frame-generation is that it can't predict when the scene is dramatically changing, which results in ghosting. Some of the presets by NVIDIA are designed to counter ghosting. It's important to note here, that unlike DLSS 2 presets, which were essentially tiers based on the actual rendering resolution; DLSS 3 presets cover a multitude of factors besides the rendering resolution and target resolution for upscaling; and not all presets are made available to games that support DLSS 3. Modders have, however, figured out ways to enable certain unavailable presets. It turns out, that NVIDIA is developing a new DLSS 3 preset exclusively for Unreal Engine 5, called Preset-G. A presentation by the Unreal Engine team detailing DLSS 3-related features in UE 5.2, inadvertently revealed this preset as they were presenting a DLSS 3 plugin, and a drop-down menu revealed the various presets, ranging from A thru G. At this point we don't really know what the G-preset includes, or what it's optimized for, but we should learn about it soon, as NVIDIA updates the public documentation for DLSS 3.
