Destiny actually scales pretty damn well. Ur not gonna get 4k, but Jayz2Cents tested at minimum specs, and it actually ran pretty well, right around 50-60 fps on low settings, if i remember correctly.
one thing very few have ever bitched about for lack of material; Destiny's PC optimization was top-notch. and that surprised the fuck out of me, since Bungo hadn't made a PC game in decades. maybe Activision sent some Blizzard employees to make sure everything went as smooth as possible for the port, or maybe Activision-Blizzard are one of the few companies out there who give a fuck about how well a game runs on PC. maybe they let a few CoDs be shit on PC and learned that lesson the hard way...I wouldn't know, i dont play that.
