Nvidia’s G-Assist was originally an April Fools’ prank in 2017 before becoming a real tech demo last year and a functioning AI assistant for RTX GPU owners today. Project G-Assist is now available inside the Nvidia app, and will help to optimize game and system settings, measure frame rates, and even change the lighting on connected devices.

G-Assist works as an AI assistant through voice or text prompts, so you can ask questions like “How does DLSS Frame Generation work?” and the assistant will give you a ChatGPT-like output. Where it gets a lot more interesting is the ability to ask G-Assist to optimize games for the best performance or image quality, or have it control the lighting of supported devices from Logitech, Corsair, MSI, and Nanoleaf.

You can even ask G-Assist to analyze and optimize your entire PC, so it will detect if a game has a frame rate limiter, whether performance of your GPU is limited, and what you can do to improve overall performance. It can even detect if refresh rates aren’t maxed out on a display and recommend options like overclocking a GPU or lowering in-game resolutions to hit a desired frame rate.

G-Assist uses a local small language model that requires nearly 10GB of space for the assistant functions and voice capabilities. The AI assistant works on a variety of RTX 30-, 40-, and 50-series desktop GPUs, but you’ll need a card with at least 12GB of VRAM.

G-Assist is available as an optional part of an update to the Nvidia app that also includes new DLSS override options and the ability to adjust display scaling and color settings. You can download Nvidia’s app right here.
