NVIDIA Showcases DLSS 4, Path Tracing, and RTX Mega Geometry with New Downloadable Bonsai Diorama Demo
NVIDIA has officially released a new Bonsai Diorama tech demo, available for download, designed to highlight the company’s latest breakthroughs in real-time graphics, including DLSS 4, Path Tracing, and RTX Mega Geometry. This demo accompanies the Unreal Engine RTX Branch 5.6.1 update, which integrates performance and visual improvements to ReSTIR PT, the DLSS 4 suite, and RTX’s most advanced geometry rendering features.
The Bonsai Diorama demo serves as a full-feature showcase for NVIDIA’s cutting-edge rendering technologies. It features DLSS Super Resolution, DLSS Ray Reconstruction, and DLSS Frame Generation, all part of the DLSS 4 package. Players can test these features interactively to compare quality modes (Off, DLAA, Auto, Quality, Balanced, Performance, and Ultra Performance) as well as Frame Generation multipliers (Off, Auto, 2x, 3x, 4x).
The star of the showcase, RTX Mega Geometry, builds upon Unreal Engine 5’s Nanite system by integrating full-quality geometry directly into the ray tracing bounding volume hierarchy (BVH). The result is significantly improved shadow and reflection accuracy, effectively eliminating the visual artifacts often found in UE5’s default path-traced scenes.
According to NVIDIA, this system debuted in Alan Wake 2 and is now being further refined for developers and creators aiming to balance fidelity and real-time performance.
To experience the Bonsai Diorama demo, NVIDIA recommends using the following hardware setup:
Minimum GPU: GeForce RTX 2080 Ti
Recommended GPU: GeForce RTX 5060 or higher
Driver Version: GeForce 581.29 or newer
Resolution and display options can only be configured before loading the level. NVIDIA suggests starting in fullscreen mode, with 1080p or 1440p for 8 GB cards, and 4K resolution for GPUs with 11 GB VRAM or more. Pressing H during gameplay brings up the in-demo UI, allowing real-time toggling of RTX Mega Geometry, Ray Reconstruction, and DLSS settings.
A developer webinar is scheduled for Thursday, October 28, at 10 AM Pacific Time, where attendees can explore the Bonsai Diorama demo’s design and ask NVIDIA engineers about RTX Mega Geometry and DLSS 4 integration.
In related news, NVIDIA ACE (Avatar Cloud Engine) now supports Alibaba’s open-source Qwen3-8B AI model as an In-Game Inferencing (IGI) SDK plug-in, enhancing real-time character reasoning and dialogue systems. The update simplifies integration into development pipelines and improves the concurrent performance of AI and graphics rendering.
Enhancements to the IGI SDK include:
MultiLORA adapters for faster fine-tuning with minimal computation overhead.
CUDA support for Vulkan backends, ensuring smoother joint execution of graphics and AI workloads.
By combining ACE’s generative AI character technology with the rendering power of RTX and DLSS 4, NVIDIA is reinforcing its position at the forefront of next-generation game development tools, where visuals, physics, and AI all evolve together in real time.
Are you planning to test NVIDIA’s new Bonsai Diorama demo or waiting for these technologies to arrive in your favorite games?
