Wondering if anyone else is running a intel 2700k cpu or a 2600k cpu as I'm starting to see it bottle neck , I have it over clocked to 5.0 ghz doesn't run hot and have 2 rog gtx 780ti in sli and run 1440p ultra hbao god rays low with shadow boost app ,I don't drop below 63 fps in have cities but even on max 1440p in cities the gpu ussage drops down . Wondering if any one else has saw the cpu bottle neck in this game and would a newer cpu such as a 5930k 6 core or a 6700k make that much of a difence ?

Did you enable V-sync or cap framerate?

The CPU really isn't used that heavily, at least on my setup.
