Ultimate Terrain setup help needed

I have finally decided to give UT a try and downloaded it tonight. I have not installed it yet but I remember seeing threads awhile back about how to set it up as far as what settings to use ect. I am currently using GEXn and FEX if that makes any difference in the setup and you can see my system in my sig. Does anyone have a link to how to setup UTX or have a list of the best settings to use?
Thanks, Jim
