Nvidia announces DLSS 3.5 "Ray Reconstruction" for all RTX-branded cards (www.youtube.com)

Replacing the usual denoising algorithms used to generate an image from the (usually small) number of traced rays in a scene with a new AI model that runs alongside DLSS upscaling, Nvidia is able to show ray traced reflections and shadows with less artifacts, significantly improved clarity, and more data points being represented (like soft shadows and small occlusions) at no penalty to performance.

Unlike frame generation, DLSS 3.5's ray reconstruction will work on all RTX series cards, including the 2000 series. In one example, Nvidia shows how fast moving objects no longer leave trails of temporal artifacts when RT global illumination is enabled.

As always, this will require games to be updated to support the new features, and this can't be enabled by a simple DLL swap. At the moment, a few games, including Alan Wake 2 and Cyberpunk 2077, are announced to be working on implementing DLSS 3.5.

This is very exciting. Unfortunately, AMD card won’t be able to benefit from this, making the GPU market ever more fragmented.

How does this fragment anything? DLSS and Nvidia's ray tracing tech have always been exclusive to their own RTX cards. Nothing changes in that respect. Ray tracing, as a whole, isn't exclusive to Nvidia, but their tech has been.

It's a bit annoying that they called it DLSS 3.5 even though it has nothing to do with DLSS 3. This is an enhancement for ray-tracing whereas DLSS 3 is frame-generation, you'd think the .5 means it's just an enhanced version of that.

Nvidia's updated naming scheme actually asks developers to drop the "DLSS 3.0" name for frame generation. Menus should call the feature "DLSS Frame Generation" and it's a separate toggle. DLSS 3.5 now includes supersampling, ray reconstruction and frame generation, where the first two features are available for all RTX cards and enabled together, and the latter is exclusive to the RTX 4000 series and enabled separately.
