blurry distance ground texture

Hi all,
I know i fixed this by changing some thing in fs9.cfg but can't remember where i saw it or what the fix was.. whats happening is you can see a line of sharp to blurry ground texture in the distance... i remember it being something like the amount of ground blocks that are loaded at the same time.?? any one know what I need to change to get all ground texture sharp however far away they are?
Thanks
