For some reason Batman AC steam version stutters like crazy and causes my gtx 680 4GB ftw to use like 19 percent of the gpu when it does(I thought the Patch corrected dx11 issues a while back.) I am trying to play in dx11. I have an i7 2600k cpu overclocked to 4.5GHZ,8 GB RAM,1TB HDD,Win 7 x64 Ultimate. Please someone help me get to the bottom of this. Thanks guys
