Graphic Bug -- Checkerboard Black Squares

[Dreamer87]

Any help on getting this to go away is appreciated.

 

I'm getting this weird graphic glitch while playing Warframe.  I thought it might have something to do with lens flares or something, but I'm not sure.

 

Quite often I'll be playing and the lighting effects will cause me to get a strange overlay of black squares in a checkerboard over parts of my screen.  My FPS stays around 100 while playing, and 60 while recording.

 

My specs include an i5 3450 quad core, Radeon 7870 2gig, and 8gig of ram.

 

EDIT:  Forgot to mention that it happens most often when fighting Corpus.

 

And here is a link to a short clip of whats happening in case I didnt explain it correctly:  http://www.youtube.com/watch?v=n9sg2qmOuYk

 

Here are my graphic settings in the game:

Either a driver issue or GPU may be overheating.

My drivers are up to date, and I don't have any graphical problems running any other modern games.  Perhaps a lack of optimization is causing undue stress on my GPU and causing it to overheat?  What can I do to lessen the effect until the optimization gets an overhaul, just lower resolution?
