I don't understand how you guys are getting such bad fps.  I have an old  i7 3770k, 16GM RAM, a 970 and run on a SSD.  I get between 45-90 fps all the time.  I barely ever see it drop under 45.  I have most tings set to High.  MSAA off and AF set to 2x.  Pixel Density I change depending on what I am flying.  If I had a newer i7 and better graphics card like most of you I would assume I would get much better.
