I downloaded the demo and have noticed some strange graphics behavior.

In the first scene, the post effects being turned on creates a weird split screen zoomed in effect, but is fine with post effects turned off. In the second scene, it actually looks like with post effects turned on, but notice the black bar at the top when post effects are turned off. I noticed that the scene in general seems to be zoomed in a bit when post effects are turned on. Also, the resolution in the settings is at 1280x720, but when I take screenshots, they come out at 1440x900. The 'zoomed in' effect I mentioned could be the game using the correct setting of 1280x720, while when post effects are off it uses 1440x900, just an idea.
