So I tried to get an idea of how far those draw distance numbers might equal in terms of in-game visualization.
I used the grass...
These were the default settings in my .ini:
fGrassStartFadeDistance=7000.0000
fGrassMaxStartFadeDistance=7000.0000
Which produces this: (look at lower left cornerish)

I changed them to 100000 and this is the result from same spot:

Not exactly a huge visual difference from that height. So if anyone finds the settings, they'd have to be changed a whole lot. Saw one .ini setting with a 1,000,000 number.

Otherwise just need better drawn textures etc.
