Yeah you need LLVM 3.9 not just for this game, but also for many other
games to work correctly. It's due to the fact that some games require
GL 4.3, which is only supported with LLVM 3.9. Some games don't even
report an error when they don't get GL 4.3, they just run broken.
(like Alien Isolation)

This is unrelated to the graphics driver. The driver has no control
over what the window manager does.
