Downloading digital deluxe edition (very slow)


So I’m somewhere where the Internet speed is absolutely abysmal and I’m trying to download the digital deluxe version of evolve. It’s at 16.03GB/26.10GB and when I look at the main menu of evolve it says the game is installed at 51% so halfway there. but it’s taking over an hour just to download 1gig on this terrible Internet.

My brother owns the physical copy of the game so my question is if I put his disc in will it install everything I need at a way faster pace? Although I’m scared it will leave out the extras that come with the deluxe version if I were to do that? I’m not even sure if this is possible just an idea. Been downloading this game since 6pm the other day -_- I’ll be lucky if I get to play it by tomorrow night with these speeds.
