Is there a way to reduce view distance to increase performance?

I am creating a large landscape and I was wondering how I would I go about reducing the view distance to increase my frame rate? I was doing great and then I started adding foliage and my frames dropped quite a bit, unless I was looking at the sky. I try adding fog but that didn’t help much. My frames atm are around 20 - 25.

I figured out that you can adjust the Cull Distance for your foliage in the foliage settings. This help my frames go back in the 100’s while keeping a great look. link text
