I just dropped 60 dollars to install Far Cry 4, so excited may i mention by how great Far Cry 3 was. Far Cry 3 was amazing and ran so smooth. With FC4 I can't play more than 2 minutes due to crazy lag. The mouse movement just doesn't feel like FC3 either and rough. It seems anytime i depart i just lag and lag and freeze. Even with my setting on my 3500 dollar computer down to medium. How to fix? Thanks
