At Gamescom NVIDIA delivered the first major update to Project G-Assist, its experimental on-device assistant for tuning RTX systems by voice or text. The headline change is a new, more efficient model that uses 40% less VRAM while retaining response accuracy. That efficiency translates into broader compatibility: G-Assist can now run on all RTX GPUs with 6GB or more of VRAM, including many laptops. The update also sharpens tool-calling intelligence and introduces a new G-Assist Plug-In Hub powered by mod.io to make discovering and installing extensions easier.
G-Assist acts as a central command center for PC tuning, designed to cut through buried control panels and utility menus. Users can run diagnostics to optimize game performance, display or chart frame rates, latency and GPU temperatures, and adjust GPU or peripheral settings such as keyboard lighting. Getting started requires the NVIDIA app and the Game Ready Driver issued on Aug. 19; after downloading the G-Assist update from the app home screen, press ´Alt+G´ to activate. NVIDIA said a follow-up update in September will add laptop-specific commands for features like NVIDIA BatteryBoost and Battery OPS.
The new G-Assist Plug-In Hub is a key part of the release. Built in collaboration with mod.io, the hub lets users ask G-Assist what plug-ins are available and install them using natural language thanks to a mod.io plug-in. NVIDIA showcased a G-Assist Plug-In Hackathon with finalists that include Omniplay for in-game lore and notes, Launchpad for app groups, and Flux NIM Microservice for generating on-device images. Plug-ins are based on JSON and Python, and NVIDIA´s Plug-In Builder simplifies creation by enabling natural language driven development. Hackathon winners were scheduled to be announced on Aug. 20.
NVIDIA also highlighted updates to RTX Remix, its modding platform for modernizing classic games. RTX Remix has grown to hundreds of active projects and more than 100 released mods with over 2 million downloads. At Gamescom NVIDIA named contest winners such as Painkiller RTX Remix, and previewed a path-traced particle system coming in September that brings fully simulated physics, dynamic shadows and realistic reflections to visual effects. That particle support will open particle creation to over 165 RTX Remix-compatible titles, and modders are already using linked workflows like RTX Remix plus ComfyUI to restore and remake textures with physically based materials and immersive path-traced lighting.
