I have a GTX 1080 and a Core i7 5960x (Haswell-e), which means I should be getting good fps at 1440p, Ultra settings based on the official recommended specs. But I cannot even break 30fps on Medium at 1080p. In fact, there is literally no difference when I turn every settings to Low. Before anyone ask, of course I am running the latest Nvidia driver and with all the hotfixes installed.
So the problem is not with your hardware. It's just a sh*tty game.
