Are there any benefits at all to plugging in my Xbox 360 into my Xbox One? Like does it make the Xbox 360 graphics look better, or is just using the Xbox One as an addition hdmi input the only benefit?
I don't pick sides. I play on both and I watch from the sidelines. Xbox360/One + PS3/4 + Wii U + PC = Awesomeness!!!
It's well known that it will cause lag that makes some games unplayable. Some people have said it doesn't bother them. You will have to try it for yourself to see if it is ok for you. I didn't bother but how hard is it to plug an hdmi cable in and find out for yourself?
