At #GDC2026, we’re unveiling a ton of updates across path tracing, on-device AI models, and developer tools. Here’s a few of the highlights: * New system for path-traced foliage in NVIDIA RTX Mega Geometry * Optimizations for path-traced mirror reflections and strand-based hair in @UnrealEngine * On-device, production-quality TTS model in NVIDIA ACE Get the full details 👉 nvda.ws/4bjLltg

We’re accelerating Unreal Engine’s Neural Network Engine (NNE). NNE is a common API that allows for seamless integration of neural network features in @UnrealEngine 5. Now, developers can utilize a new plugin that adds TensorRT for RTX as a runtime option, resulting in higher throughput on NVIDIA RTX GPUs.

ICYMI: Here’s 3 new releases from the month of April. 🟢 DLSS 4.5 SDK with Dynamic Multi Frame Generation and Multi Frame Generation 6X now available 🟢 TensorRT for RTX plugin for @UnrealEngine’s Neural Network Engine 🟢 NVIDIA Kimodo: a kinematic motion generation model, synthesizing realistic 3D character animation from simple inputs Full details in blog 👉 nvda.ws/4t2Qr41

This week's Level Up With NVIDIA webinar is all about path traced hair in @UnrealEngine 5.7. We'll also be covering the latest features and support of NvRTX, plus recapping our “State of RTX Rendering in Unreal Engine 5” talk from GDC. 📆 Apr 29, 10:00 AM PDT 🔗 nvda.ws/4ugNOwn

In case you missed it, @NVIDIAGameDev posted @adamcrei's & @kevinnappoly's GDC talk about porting the Slang shading language to consoles: youtu.be/dfRownfn6NY?si… It's more than just a proof-of-concept.... 😉

Today, we released Lyra 2.0, a framework for generating persistent, explorable 3D worlds at scale, from NVIDIA Research. Generating large-scale, complex environments is difficult for AI models. Current models often “forget” what spaces look like and lose track of movement over time, causing objects to shift, blur, or appear inconsistent. This prevents them from creating the reliable 3D environments required for downstream simulations. Lyra 2.0 solves these issues by: ✅ Maintaining per-frame 3D geometry to retrieve past frames and establish spatial correspondences ✅ Using self-augmented training to correct its own temporal drifting. Lyra 2.0 turns an image into a 3D world you can walk through, look back, and drop a robot into for real-time rendering, simulation, and immersive applications. ➡️ Learn more: research.nvidia.com/labs/sil/proje… 📄 Read the paper: arxiv.org/abs/2604.13036

Shader debugging often consists of having to iteratively insert printf statements or re-reproduce the issue with each new hypothesis. Using Nsight Graphics’ new Shader Debugger you can take a complex bug, find warps that show the issue, and quickly narrow it down to its root cause. Check out the video for a full example walkthrough ➡️ nvda.ws/41i6lfk

New announcements from #GDC2026 📣 In collaboration with @Microsoft, we are standardizing hardware-accelerated AI through DirectX to boost GeForce RTX GPU efficiency and provide a unified workflow for the broader development community. Additionally, we are working to address long compilation times and in-game stuttering by evolving shader handling to distribute precompiled shaders during the game download rather than at runtime.

Last year, we introduced RTX Mega Geometry, which brings unprecedented geometric detail to path-traced worlds. By compressing geometry into clusters, it handles massive scenes and updates them up to 100x faster than previous methods. At #GDC2026, we showcased a new foliage system coming to RTX Mega Geometry that aims to tackle the demanding compute and memory requirements found in large-scale natural environments.
