NVIDIA to Give Unreal Engine 5 an Exclusive "G" DLSS 3 Preset
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.

Because, why not, the leather boy needs his trillion dollar company to produce.

And thats the problem.
Nvidia needed a new marketing thing, because when every GPU can do 60 FPS in anything then whats the point? . So RT it was. But RT is massively complex and doing so in real time even more so, therefore DLSS came to be in order to make RT possible. That's still the case, heavy RT will cripple even the 4090 at 4k and sometimes even 2k, hence you need DLSS.
What will be interesting is with blackwell, or its successor, when RT is possible even on low end cards. What will nvidia market then?
The point of raytracing was increasing picture quality with realism while using properly accurate reflections & shadows instead of half-done half-bake pre-rendered solutions.
the whole point of D.L.S.S is to make the picture quality worse to increase FPS.
DLSS is good for low to mid range cards, not a 4090.
You shouldn't forget that Turing didn't stagnated, hence everything after just didn't improve enough, the 4090 could be 30% slower than what it should be.
As far as RT is concerned, it's useless due to its cost, and doesn't offer anything special.
