Likewise with vegetations, in ge3.ini they are high, but in my useroptions.ini they are the correct, medium. (Use medium cause its easire to forsee a Boar attack coming).
Maybe that has something to do with the used shader model or you need a restart.
I had shaders on 1.4 (I was too lazy to restart the game to set it too 3.0) and set the grass from low to high, but nothing changed. Then I switched too shaders 3.0 and let the game restart. All of a sudden the grass displayed correctly.
