It’s great because you’re using the virtual machine to do all the heavy lifting. The Steam Deck streams the video output from the internet. I’m seeing big improvements to battery life. I can game this way for 6+ hours if I wanted.
It uses around 6GB of data per hour of streaming so you need good network speed.
It synchronises your game libraries from Steam, GOG and Game Pass. It also can access your Epic library but doesn’t know what games you have.
It does not support every game. There are 1884 games playable on GeForce NOW so you need to check what you want to play is there.
Anyone play hell on earth? Think it's a great game although I never know what I'm doing on it.
Last game I played all the way through and enjoyed was halo infinite.
