Nvidia brings voice-driven NPCs and a new RTX Remix particle system to Gamescom

Two new updates from Nvidia are debuting around Gamescom: an on-device ACE speech pipeline and a RTX Remix particle system that gives modders physically‑accurate, editable particles across 165 classic games. They are both arriving in September.

ACE, the company’s generative AI toolkit, is being used in The Oversight Bureau - an upcoming dialogue‑heavy puzzle game from Iconic Interactive. Players speak to characters; speech‑to‑text feeds Iconic’s own narrative engine, which then selects pre‑recorded lines that fit the scene. The process runs locally on RTX PCs and targets sub‑second response times. The setup keeps authored writing in charge, while giving players a way to progress conversations without any menus or dialog wheels. The Oversight Bureau is due later this year and will be playable at Nvidia’s Gamescom B2B suite.

Separately, Nvidia is also launching RTX Remix, its open‑source remastering toolkit. Community work is stepping up support for older titles and adding integrations with standard art tools like Adobe Substance 3D. Nvidia is also rolling out a Remix particle editor in September for 165 classic titles that never had one. Modders can adjust look, size, count, emission, turbulence, and gravity, with lighting that matches path‑traced scenes. Recent community work includes glow/emit effects and broader format support; Nvidia’s $50,000 Remix Mod Contest at Gamescom showed off projects like Painkiller RTX. If you're interested, you can check out all mod submissions on ModDB.com.

The bigger question is adoption - we'll have to wait and see how many teams actually wire ACE into their narrative systems, and how quickly modders push the new particle tools into current (and future) remasters.
