NVIDIA expands ACE AI model library, releases new Bonsai Diorama demo with Mega Geometry for game developers

Qwen3-8B joins ACE

I still think NVIDIA ACE and similar technologies are the best practical use of game-facing AI so far. They can expand interaction and, when tied to in-game actions, make AI-controlled characters react with context. This would fit well in the next GTA or any open-world title.

If you haven’t seen ACE yet, it’s because it isn’t in many games. It’s a real-time stack for speech and reasoning that lets players talk to NPCs like they do in chat apps. ACE also enables features such as AI companions that can follow instructions, autonomous characters that adjust daily routines, and systems that plan different tactics against players.

NVIDIA offers several models that developers can choose from. The company recently added Qwen3-8B. From available material, some supported models can use up to around 16 GB of VRAM, which is a stretch for many current GPUs. Either GPU memory sizes will keep rising or smaller models will get more efficient.

Bonsai Diorama demo for Unreal Engine

NVIDIA has released the RTX branch update for Unreal Engine 5.6.1 with RTX Mega Geometry, ReSTIR PT performance and image quality updates, and the DLSS 4 suite. The new Bonsai Diorama demo ships with NvRTX 5.6.1 to showcase these features.

I don’t think it’s much use to gamers, but nothing stops you from becoming a ‘developer’ and downloading the demo to give these technologies a try.
