Oculus Air Link allows you to stream your VR games to your headset wirelessly
When it comes to the Oculus Quest 2, you can either play your games while wired in to your PC, or you can experience games in a slightly scaled-down form natively on the headset itself, without any wires. This new update, though, lets you play your PC-powered games, wirelessly. Facebook teased the Oculus Air Link, which works similarly to in-home streaming, as you'll be using your computer to run the game, but it'll be streamed directly to the Quest 2 over WiFi. Right now, Air Link is in an experimental form, and will available soon, through the Oculus application.
It's recommended that you have a 5Ghz wireless network, in addition to being within around 20 feet of your router, in order to get the best possible quality. This feature will be added in the v28 update for both the Oculus Quest 2's software and the Oculus PC program, which currently has no set release date beyond "soon". A more solid timeframe will likely be revealed in the Oculus Gaming Showcase next week. That same update will also add 120Hz support for the Quest 2 headset, an increase from the current 90Hz, allowing you to play games at a higher refresh rate, when plugged into your PC through Oculus Link.
