MY friend says it is "artifacts" but whenever I update my drivers it fucks up my whole surround and I have to redo my surround and rearrange my icons and my 4th monitor position.
He says It will damage my video card but I only bought BF4 really just to test it in surround on my 660 TI SLI and it works pretty good
and yeah it looks like crap I am holding my iphone recording it
