I hear this a lot, and this is typically a network optimization problem. Networking is hard, and "a cable with enough bandwidth" is only part of the issue. How many hops between devices? Are any devices in the chain wireless? What router are you using? How many other devices are connected to it, and what kind of load are they putting on it? FWIW, I frequently stream PS4 and PC games, wirelessly, over 802.11ac and it's more than playable. Dark Souls III, and even Overwatch, is playable over my network.
