NVIDIA has released a technical demo titled “Bonsai Diorama” that showcases the RTX feature set — from DLSS 4 to path tracing and the latest RTX Mega Geometry. The release coincides with Unreal Engine 5.6.1 and is available for anyone who wants to try the newest advances in real‑time rendering.
The demo leverages DLSS Super Resolution, DLSS Ray Reconstruction, DLSS Frame Generation, and an enhanced ReSTIR PT implementation that delivers precise lighting and high image quality for path‑traced scenes.
Minimum hardware is a GeForce RTX 2080 Ti; the recommended GPU is an RTX 5060. A GeForce driver version 581.29 or newer is required. The in‑game menu lets you choose resolution and window mode: GPUs with 8 GB of VRAM are best run at 1080p or 1440p, while cards with 11 GB or more can experience the demo at 4K.
After starting the demo, press H to open the interface. There you’ll find toggles for RTX Mega Geometry, Ray Reconstruction, DLSS Super Resolution modes (Off, DLAA, Auto, Quality, Balanced, Performance, Ultra), and the Frame Generator (Off, Auto, 2x, 3x, 4x).
The centerpiece of the demo is RTX Mega Geometry, first used in Alan Wake 2. The technology binds Nanite geometry directly into the BVH, improving shadows, reflections, and lighting while avoiding typical Unreal Engine 5 artifacts.
NVIDIA also updated ACE (Avatar Cloud Engine) — it now supports the open AI model Qwen3-8B as a plugin for the In‑Game Inferencing SDK, enabling seamless AI integration into gameplay.
New SDK features include:
- MultiLORA support for fast model fine‑tuning;
- CUDA optimizations for Vulkan, accelerating both graphics and AI workloads.
