Requiem - Graphics glitching

[AMV Ph34r]

I just started playing Requiem the other day, and immediately noticed this really weird graphical glitch. When playing the game normally, if there is a light source on the screen (normally near the center), it replicates it, magnified, at the bottom of the screen, like so:

In addition, all light sources that I am standing near, present anywhere on the screen are replicated slightly above the original source:

Finally, whenever I right-click to inspect something, it does some really weird image replication/overlap that I can't quite describe:

I have no idea what's causing these problems, and it might even be as simple as my game's graphics settings, though I haven't had time to mess around with them yet. Any help is greatly appreciated!
