Nvidia released its Bonsai Diorama demonstration software to highlight DLSS 4 technology, path tracing capabilities, and RTX Mega Geometry features. The company updated its Unreal Engine RTX branch to version 5.6.1 alongside the demo release. Users need at least a GeForce RTX 2080Ti graphics card and driver version 581.29 or later to run the program.
RTX Mega Geometry integrates full-quality Nanite geometry into ray tracing systems to eliminate visual artifacts in shadows and reflections. The technology first appeared in Remedy Entertainment's Alan Wake 2 through a performance-focused patch. Nvidia scheduled a developer webinar for Thursday, Oct. 28, at 10 a.m. Pacific Time to address technical questions.
The company added a Qwen3-8B artificial intelligence model support to its Avatar Cloud Engine platform. Developers can implement MultiLORA adapters for efficient model customization and access CUDA support for Vulkan graphics backends. The updates enable real-time character reasoning and dynamic responses to player actions without scripted events.
