DX11 comes with unique features not present in DX9 that require more processing power to render. Try turning off all the DX11-specific features in the DX11 version and compare scores to DX9.

One of the biggest framerate killers I found was Highest SSAO--I turned it to High, barely noticed the difference, and managed to get Extremely rating with a 660Ti.

I still go full PS3 during the first field sequence and the fishing bit, though.
