At the Game Developers Conference (GDC) 2025, NVIDIA unveiled a series of innovations that will have a significant impact on the future of graphics and game development. From neural rendering technologies to autonomous game characters, NVIDIA is once again demonstrating its pioneering role in the industry.
Key features of the announcements:
- Neural Shaders: integration of AI into graphics programming to improve performance and image quality.
- DLSS 4: Introduction of Multi Frame Generation for an up to eightfold increase in performance.
- RTX Remix: Release of a new playable RTX demo of Half-Life 2 on March 18.
- RTX Kit: Support for Unreal Engine 5 with new features such as RTX Mega Geometry and RTX Hair.
- NVIDIA ACE: Use of autonomous game characters in titles such as inZOI and NARAKA: BLADEPOINT MOBILE PC VERSION.
Neural shaders: A new era of gaming
In collaboration with Microsoft, NVIDIA is introducing neural shaders, which will be included in the DirectX preview in April. This technology leverages the AI tensor cores of GeForce RTX GPUs to revolutionize graphics programming. By using AI together with traditional rendering techniques, frame rates are increased, image quality is improved and resource consumption is reduced. Developers can use the NVIDIA RTX Neural Shaders SDK to train their game data and shader codes on RTX AI PCs and accelerate the neural structures with tensor cores in real time.

DLSS 4: Revolutionary performance boost
With the launch of the GeForce RTX 50 series, NVIDIA introduces DLSS 4, which uses AI to generate up to three additional frames per conventionally rendered frame through Multi Frame Generation. This results in a performance increase of up to eight times compared to traditional rendering. This massive improvement allows gamers to take full advantage of the graphics at the highest resolution and play at impressive frame rates. Over 100 games and applications already support DLSS 4, including the upcoming Half-Life 2 RTX demo.

RTX Remix: Half-Life 2 in new splendor
NVIDIA releases an enhanced version of RTX Remix, a revolutionary modding platform that enables remastering of classic games with RTX. To demonstrate the capabilities of RTX Remix, Half-Life 2 owners can download a free RTX demo on Steam starting March 18. This demo shows the results of the work in Ravenholm and Nova Prospekt and features full ray tracing, reworked assets, DLSS 4, Reflex, RTX Neural Radiance Cache, RTX Skin and RTX Volumetrics.
RTX Kit: Support for Unreal Engine 5
The NVIDIA RTX Kit, a collection of neural rendering technologies, receives major updates with support for Unreal Engine 5. With features like RTX Mega Geometry and RTX Hair, developers can create games with AI ray tracing, rich geometry and photorealistic characters. The new GeForce RTX 50-series GPUs offer a significant acceleration of ray tracing for hair and fur through the new Linear Swept Sphere (LSS) primitive. These advances enable faster and more efficient real-time rendering with tensor cores.
NVIDIA ACE: Autonomous Game Characters
NVIDIA introduces autonomous game characters debuting this month in the inZOI and NARAKA: BLADEPOINT MOBILE PC VERSION games. In the life simulation inZOI, players can create “Smart Zoi” NPCs with individual life goals that use AI to control their behavior and interactions. In NARAKA: BLADEPOINT MOBILE PC VERSION, ACE-controlled teammates support players in battle, hunting for loot and competing for victory. These technologies open up new possibilities for gameplay and interaction with NPCs.
Conclusion
NVIDIA is setting new standards in game development with its announcements at GDC 2025. By integrating AI into various aspects of gaming, from neural shaders to DLSS 4 and autonomous game characters, NVIDIA is providing developers and gamers with powerful tools and experiences. With the release of the Half-Life 2 RTX demo on March 18, gamers will be able to experience for themselves how these technologies bring a new level of immersion to classic games.
