My gaming rig does not have wireless capability, so I currently have it plugged in via ethernet. If I were to purchase a NVIDIA Shield tablet, would it still be able to stream games if it is connected to wifi and the PC is connected through ethernet? (They will still be on the same network). Also, if it can work, is the Shield able to stream from anywhere with a wifi connection? For example, could I stream games from my home PC while connected to wifi at a coffee shop? Does this require port forwarding? Thanks!
