New NVIDIA RTX Neural Rendering suite to integrate into DirectX via April preview; More games getting RTX techs

At GDC 2025, NVIDIA unveiled several new RTX technologies, with a strong focus on neural rendering. This innovation significantly reduces VRAM usage by leveraging generative AI to dynamically generate textures, polygons, and other assets in real time.

NVIDIA x Microsoft

NVIDIA is teaming up with Microsoft to integrate neural shading support into the DirectX API package, set to roll out next month. Given Windows' dominance as the primary gaming OS, this collaboration enables developers to harness AI Tensor Cores in GeForce RTX GPUs to accelerate neural networks within a game's graphics pipeline. The result? Enhanced GPU resource efficiency, improved image quality, and, in some cases, higher frame rates. On the Windows side, Microsoft is adding cooperative vector libraries to DirectX and HLSL, allowing developers and studios to fully utilize RTX Neural Shaders for more immersive gaming experiences.

RTX Kit for Unreal Engine 5

This technology significantly accelerates ray tracing in highly detailed scenes, supporting up to 100 times more triangles than current capabilities allow. Developers eager to try it out can access it via NVIDIA's RTX (NvRTX) branch of UE5. Additionally, RTX Hair is being introduced within the same update branch, enabling GeForce RTX 50 Series GPUs to render ultra-realistic hair and fur using linear swept sphere primitives. This advancement boosts both visual fidelity and performance.

Expanding RTX support for Half-Life 2 and more

https://www.youtube.com/embed/qoEQ_48ELt8 RTX Remix-enhanced Half-Life 2 has been available for four months, and modders continue to enhance the game with new content. The team at Orbifold Studios has rolled out a fresh update featuring DLSS 4 support with Multi-Frame Generation, along with RTX Neural Radiance Cache, RTX Skin, and RTX Volumetrics. Beyond Half-Life 2, several upcoming titles will launch with DLSS 4 support from day one, including Lost Soul Aside, Mecha BREAK, Phantom Blade Zero, Stellar Blade, Tides of Annihilation, and Wild Assault. More details on the visual and performance improvements brought by DLSS can be found here.

NVIDIA ACE powering NPCs in inZOI and NARAKA: BLADEPOINT MOBILE PC VERSION

https://www.youtube.com/embed/Pk9z1upOj3U The upcoming life simulation game inZOI, launching on March 27, will incorporate NVIDIA ACE-powered autonomous game characters via the "Smart Zoi" experimental feature. This system utilizes the 0.5B parameter Mistral NeMo Minitron LLM to deliver intelligent, low-latency responses in a compact AI model. https://www.youtube.com/embed/I65tiaHQuFk Similarly, NARAKA: BLADEPOINT MOBILE PC VERSION will feature an ACE-powered AI teammate in Free Training mode. This AI companion can join parties, assist in battles, and provide suggestions for builds, gear swaps, and more.
