Last year, Nvidia released RTX Voice, a pretty good GPU-driven noise-cancellation technology that could be hacked to run on non-RTX graphics cards. Since then, it turns out that Nvidia has quietly and officially unlocked the ability to reduce outside noise when using a microphone on systems with lower-powered GTX-level graphics cards as well.
A quick hat tip to Tom’s Hardware, which recently noticed an extant version of Nvidia’s RTX Voice Setup Guide. It currently notes that “to use RTX Voice, you must be using an NVIDIA GTX or RTX graphics card, update to Driver 410.18 or newer, and be on Windows 10 [emphasis added].”
The addition of GTX cards to the “requirements” section of the guide was made around the end of October 2020, according to a quick perusal of the Internet Archive. About a month before that, Nvidia added an update to the page noting that “RTX Voice is now enabled for any NVIDIA GeForce, Quadro or TITAN GPU [emphasis added].”
