When my camera looks off into the distance, the fps drop from 66 to 40-45.

I was debugging using the statistics panel, and noticed that when this happens, In the Geometry section "ent: time for entity rendering" raises from 5.0 - 20.0

Why is this? How can I fix it? Is this the problem that causes my games Fps to drop when There is a distance / two layers of map..?
