Searching on web I know this is a problem for some people,I just can't find a solution!
I've forced the ambient occlusion with nVidia inspector,Diablo III compability, but nothing changes.Anyone unlucky guy like me find a way? With 2k13 I had no problem (but I had a gtx560ti),now with a palit gtx780,latest drver 331.82,windows7 64,no shadows!
