Inconsistent gamestream input lag (Xbone & PS4)

I'm able to stream my PS4 very well to my iPhone at 720p, but streamed to my gaming laptop, it has a half-a-second (sometimes more) input lag at the same resolution. The weird thing is: even if I go through an ethernet cable, the delay is unchanged. And it's not the controller to the laptop, cause I can play games that are rendered locally with no perceivable input lag with the same controller. I don't understand what's going on. The Xbox One's stream has slightly better input lag (still awful), but suffers from severe screen tearing. It's not always like this, however. A couple days earlier things were working flawlessly. It's just the luck of the draw if I want to stream my consoles to my laptop.

Any ideas?

Thanks.
