Well I reinstalled it & looks fantastic in 4K ! However , the only setting I can't max out is the AA . I normally don't use it in 4K , but my gpu usage needed a "kick" & was greeted with the game freezing up . Tried it again & it locked up the pc . So back to no AA ... still looks good . Might even play Far Cry 3 that's been sitting on my desktop since ... last year I thinks ....
