At first run I couldn't click on any main menu options with a controller or keyboard. Once I shut everything down (thinking that it just didn't work) and came back to it a few hours later, this issue was gone. The game mostly runs fine. I had to turn off SSAO to get it to run somewhat smoothly. Even after that, it suffers from intermittent "micro" stutters -- bouncing back and forth between smooth gameplay and slight stuttering.
