Some of them will soon see their first games.
We’ve already written about the introduction of RTX 50 graphics cards and a number of technologies as part of the DLSS 4 package. However, Nvidia announced many more new features, albeit a little hidden. These are more options for developers, but we will soon see some of them in the first games. All of them are included in a package called RTX Kit, which should be released soon.
RTX Neural Shaders
First up, we have neural shaders, which Nvidia says allow small artificial intelligence networks to be used inside shaderswhich can be used in different ways, as we will show below.
By the way, Microsoft also joined the announcement, promising that DirectX 12 Ultimate will be released soon. support for cooperative vectorswhich should speed up AI operations, including neural shadowing.
RTX Neural Texture Compression
One use case for neural shaders is neural texture compressionwhich was first discussed several years ago. The technology uses artificial intelligence to, as the name suggests, compress the textures they have. take up to 8 times less space in video memory compared to traditional compression, namely while maintaining quality.

Classic vs. nerve compression
RTX texture filtering
Also texture filtering can use AI, technology in new ways reduce artifacts and improve image quality.
RTX Neural Materials
Next we have neuronal materialswhich use AI to compress the shader code of complex multi-layer materials for up to 8 times faster processing. NVIDIA promises Real-time performance with blockbuster-quality resources.

RTX Neural Radiation Cache
Neural Radiance Cache, or NRCis a new RTX Global Illumination component used for indirect lighting. NRC uses AI to predicting the amount of light that is emitted or passes through a certain area.
NVIDIA promises not only better lighting qualitybut also Better gaming performance using path tracing.
RTX Mega Geometry
Game geometry is constantly becoming more complex, especially recently with the introduction of Nanite technology in Unreal Engine 5. This is why Nvidia came up with this technology. RTX Mega Geometrywhich allows faster creation of BVH structures And up to 100x more ray-traced triangles. At the same time, technology must provide better performance in path-traced headers.

No against. with Mega Geometry
Mega Geometry already has its first game announced. he will appear in Alan Wake 2 on January 30th when DLSS 4 releases..
Neural faces RTX
It highlights Nvidia as one of the main features neural faces. This is an artificial intelligence model that is trained on data from an original face that is expanded by different lighting conditions, emotions, or occlusion. Model subsequently it takes the original face and generates an improved version of it in real time.
RTX Skin and RTX Hair
Technology is also connected to characters RTX Skin and RTX Hairwhich, as the name suggests, are aimed improve the quality of skin and hair. For this purpose it is used in case of leather. subsurface scattering with ray tracing and RTX Hair uses strand based hairas we saw, for example, in RE4 or Dragon Age: The Veilguard.
This is technology RTX Hair is heading to Indiana Jones and the Big Circle soon..
