Sorry that I'm unable to attach an image to give you a better understanding of what the heck I'm talking about, but is anyone experiencing large blocky artifacts around every explosion in Bad Company 2. It  primarily occurs when rockets/grenades hit and break apart buildings. Once again I apologize for the vague description of my issue. 

I've tried re-installing the game, and have updated drivers, even gone as far as to go back to previous drivers prior to 12.8, but issue still occurs.
