Hi, I tried to play streams games on iPad Pro via jump-desktop and a PC in another room. The performance for even 2D game is not so good. Then I read that one could use Steam Link. What are the advantages doing it that way? I tried to try it but my MS Xbox Controller cannot be paired with my iPad via Bluetooth. Perhaps it does not have Bluetooth as I think I have a receiver on my PC. In case of needing to buy a new controller, which is the recommended one to buy?
