Unfortunate noob question

[MasterTonberry]

Right, this has been bugging me for about 2 years so i'm just gonna ask.

What does 'Use High Detail Terrain' in the options menu do? It makes no difference to the terrain.....so can someone enlighten me?

No Idea..Maybe when zoomed in? I use blue marble anyways

I don't know either but Genv's idea about zooming in sounds good. I play with it off because I didn't see anything different either.
