GeForce Now is a great way to game on a handheld gaming PC, such as a Steam Deck. You can play games that aren't available on that Linux-powered handheld.
For example, Destiny 2. And usually you'll save heaps of battery by streaming rather than playing locally. What's not been so great is trying to install GeForce Now as something akin to an easy-to-use app.
It's traditionally required a good deal of tweaking, and I've long wished for a GeForce Now app on Steam Deck. Thankfully, Nvidia is now going to do the brunt of that fiddling with the settings for you.
New GeForce Now installation files are now available for Steam Deck, ROG Ally, Legion Go, and the MSI Claw. These include a script that will effectively install Google Chrome, the web browser of choice for running GeForce Now, and tweak its launch options to optimise for each handheld.
You might be wondering why you need to install a browser-based game streaming service at all, but, on the Steam Deck at least, it's not possible to use the Steam Deck's many controller configurations through Google Chrome (and therefore while playing games on GeForce Now) without some further tweaks to the browser.
