MacOS and Windows users can now enjoy the full GeForce Now! It is now available to use the service using the Chrome browser.
You can head over to play.geforcenow.com and begin to play as long as you want, so long as you are a subscriber. But be reminded, Nvidia will still require you to use the appropriate application rather than the web app to reap the full optimal experience without the hassle of downloading the software online or trying it out before extending your subscription.
