I've used Steam and PS4 Remote Play fairly extensively in my home so I have some experience with the concept. I think it really it depends on the game.

Fallout 4: Works great.

Dark Souls 3: The latency is immediately obvious. You might as well be torturing yourself, the game is already hard enough.

God of War: somewhere in the middle. It's playable, but it feels crisper without the extra latency.

I don't see how this product will be any different.
