Basically it lets you fire up & use the Edge Browser directly from the Game Bar. If you Alt + Tab out of a game it doesn't always survive, but by being part of the Game Bar, Edge in this case can sort of coexist.
We know that staying focused on your game is important, yet you also need to look up game guides, connect with friends, or even listen to music if you want while you play. Alt-Tabbing from the game to the desktop is common practice, but it takes you out of your immersive experience. Depending on the game, it can also be quite slow or may even cause issues with the game. Today, we’re excited to announce that Microsoft Edge Game Assist is available worldwide1, allowing you to quickly access the web without leaving your game. Say goodbye to Alt-Tab and simply press Win+G to open Game Bar and start using Microsoft Edge for a more seamless and immersive experience.Game Assist is the first in-game browser built specifically with PC players in mind, featuring tips and guides for many of the top PC games, easy access to essential sites like Discord, Spotify, and Twitch, and more — all right in your game. Everything you need is on one screen so you can stay focused on the action without interruption. You can also pin Game Assist above your game to reference guides or watch videos while you play. And because it’s connected to your Edge browser, you’ll have instant access to your favorites, passwords, history, and more – ensuring everything you need is always within reach.
