I'll spare you guys the need to watch that one guy's video that people keep linking to: you need to add "-force -dx11" (minus the quotes, and mind the dashes and the space) in the game's launch options. Without those arguments, mine was still getting stuck on a black screen after launching.
I'd like to add that linking a damn video when the instructions are so simple is a waste of everyone's time. It's even worse considering that the actual launch option only appears on-screen for about 2-3 seconds before he moves on to showing in-game footage. He doesn't even stop to address it other than saying "it works with only one tweak".
