Increasing Autogen draw distance?

ok im trying to make fs9 look as good as possible, without having to step up to fsx, because for whatever the reason my computer won't handle that game.. But FS9 I am getting very stable 40-50fps.
Ive installed all the reccomended things, and the autogen tree booster, so it actually looks like a forest :p lol I love that one :p
but anyways.. how can I increase the draw distance of autogen, and/or the general draw distance..
Ive maxed all the settings, and in the fs9.cfg, ive set the terrain as follows:
[TERRAIN]
TERRAIN_ERROR_FACTOR=100.000000
TERRAIN_MIN_DEM_AREA=10.000000
TERRAIN_MAX_DEM_AREA=100.000000
TERRAIN_MAX_VERTEX_LEVEL=19
TERRAIN_TEXTURE_SIZE_EXP=8
TERRAIN_AUTOGEN_DENSITY=5
TERRAIN_USE_GRADIENT_MAP=1
TERRAIN_EXTENDED_TEXTURES=1
TERRAIN_DEFAULT_RADIUS=50
TERRAIN_EXTENDED_RADIUS=50
TERRAIN_EXTENDED_LEVELS=50
what more can I do to increase the graphics, and get a usless 40fps down to 25 usuable awsome looking fps
thanks a lot guys!
