So there are programs like GeForce Now which DE have opted into. There's also Steam Link and some other ones. Some use your own network. Others use a datacenter to host the game and it streams your inputs onto their hardware. As far as the game is concerned your IP is where ever say Nvidia has their closest data center.
The ability to use Nvidia's hardware is great for seeing if a bug is your hardware or a recent update. It's also great for people who lack the ability to update their hardware.
So it'd be nice to have clarification if we risk getting banned now if we use Geforce Now, Steam Link, Xbox Cloud Gaming, Shadow Play, Playstation Now, Luna, etc.
I doubt it but it's nice to have a reference to point have. Considering in Geforce Now's case as I stated games aren't automatically added to their service. Dev's need to give the go ahead. But it's still technically a VPN.
