One thing is for certain watching IGN's Battlefield 1 graphical comparison video, this game is gorgeous no matter how you play it! Truthfully, the game looks just as good on low as it does on high! I notice a couple objects missing on the low setting but it appears the important stuff is there in both versions.
I wonder if that means the game takes some power to run at minimum or it's just really efficient? I'm guessing it's the former. See the video below.
