Hey there! I'm led to believe this might be related to any overlays you could be using, bad video card driver that needs to be reinstalled, or corrupted files within the game folder. Let's see if these steps below help out.
Feel free to include a DxDiag if you need more help so we know what system specifications you have. Good luck and thanks for the report!
How to gather DxDiag information
Have you tried setting your graphical settings to default from the Nvidia Control Panel and in-game? It leads me to believe it's artifacts showing up from the video card. Do you use other type of software for your graphical settings?
Can you disable ambient occlusion in video options and advise if any change.
