Nvidia follows Amazon down the path of least resistance to get its cloud-gaming service onto your iOS device. Like , Nvidia GeForce Now has come to the iPhone and iPad by way of Apple's Safari browser, now in beta. The company has also updated its roadmap for the service, promising the ability to run in the Chrome browser on Linux, PC, Mac and Android devices starting early next year, and that it will support GOG games at some unspecific point in the future, likely beginning with The Witcher 3: Wild Hunt and the eagerly anticipated Cyberpunk 2077. Both of those games come from GOG's sister company, CD Projekt Red.
Apple requires afor these services to meet Apple's policies in order to be sold in the App Store (imagine if every movie and show on had to be in a separate app and approved independently), so services like GeForce Now and need to resort to operating within Safari. Safari provides the most app-like experience because it's the only browser Apple allows to add shortcuts to your home screen in iOS.
One big caveat for GeForce Now on iOS is you can only play games with a controller -- no keyboard and mouse or touch -- and that will cut a chunk out of your selection of playable games. But the company is specifically working on a touch version of Fortnite in conjunction with Epic.
