Nvidia’s AI assistant is here to optimize your gaming PC

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.
